Danny Avila	a26eeea592	🔏 fix: Enforce MCP Server Authorization on Agent Tool Persistence (#12250) ... * 🛡️ fix: Validate MCP tool authorization on agent create/update Agent creation and update accepted arbitrary MCP tool strings without verifying the user has access to the referenced MCP servers. This allowed a user to embed unauthorized server names in tool identifiers (e.g. "anything_mcp_<victimServer>"), causing mcpServerNames to be stored on the agent and granting consumeOnly access via hasAccessViaAgent(). Adds filterAuthorizedTools() that checks MCP tool strings against the user's accessible server configs (via getAllServerConfigs) before persisting. Applied to create, update, and duplicate agent paths. * 🛡️ fix: Harden MCP tool authorization and add test coverage Addresses review findings on the MCP agent tool authorization fix: - Wrap getMCPServersRegistry() in try/catch so uninitialized registry gracefully filters all MCP tools instead of causing a 500 (DoS risk) - Guard revertAgentVersionHandler: filter unauthorized MCP tools after reverting to a previous version snapshot - Preserve existing MCP tools on collaborative updates: only validate newly added tools, preventing silent stripping of tools the editing user lacks direct access to - Add audit logging (logger.warn) when MCP tools are rejected - Refactor to single-pass lazy-fetch (registry queried only on first MCP tool encountered) - Export filterAuthorizedTools for direct unit testing - Add 18 tests covering: authorized/unauthorized/mixed tools, registry unavailable fallback, create/update/duplicate/revert handler paths, collaborative update preservation, and mcpServerNames persistence * test: Add duplicate handler test, use Constants.mcp_delimiter, DB assertions - N1: Add duplicateAgentHandler integration test verifying unauthorized MCP tools are stripped from the cloned agent and mcpServerNames are correctly persisted in the database - N2: Replace all hardcoded '_mcp_' delimiter literals with Constants.mcp_delimiter to prevent silent false-positive tests if the delimiter value ever changes - N3: Add DB state assertion to the revert-with-strip test confirming persisted tools match the response after unauthorized tools are removed * fix: Enforce exact 2-segment format for MCP tool keys Reject MCP tool keys with multiple delimiters to prevent authorization/execution mismatch when `.pop()` vs `split[1]` extract different server names from the same key. * fix: Preserve existing MCP tools when registry is unavailable When the MCP registry is uninitialized (e.g. server restart), existing tools already persisted on the agent are preserved instead of silently stripped. New MCP tools are still rejected when the registry cannot verify them. Applies to duplicate and revert handlers via existingTools param; update handler already preserves existing tools via its diff logic.	2026-03-15 20:08:34 -04:00
Airam Hernández Hernández	aee1ced817	🪙 fix: Resolve Azure AD Group Overage via OBO Token Exchange for OpenID (#12187) ... When Azure AD users belong to 200+ groups, group claims are moved out of the ID token (overage). The existing resolveGroupsFromOverage() called Microsoft Graph directly with the app-audience access token, which Graph rejected (401/403). Changes: - Add exchangeTokenForOverage() dedicated OBO exchange with User.Read scope - Update resolveGroupsFromOverage() to exchange token before Graph call - Add overage handling to OPENID_ADMIN_ROLE block (was silently failing) - Share resolved overage groups between required role and admin role checks - Always resolve via Graph when overage detected (even with partial groups) - Remove debug-only bypass that forced Graph resolution - Add tests for OBO exchange, caching, and admin role overage scenarios Co-authored-by: Airam Hernández Hernández <airam.hernandez@intelequia.com>	2026-03-15 19:09:53 -04:00
Danny Avila	ad08df4db6	🔏 fix: Scope Agent-Author File Access to Attached Files Only (#12251) ... * 🛡️ fix: Scope agent-author file access to attached files only The hasAccessToFilesViaAgent helper short-circuited for agent authors, granting access to all requested file IDs without verifying they were attached to the agent's tool_resources. This enabled an IDOR where any agent author could delete arbitrary files by supplying their agent_id alongside unrelated file IDs. Now both the author and non-author paths check file IDs against the agent's tool_resources before granting access. * chore: Use Object.values/for...of and add JSDoc in getAttachedFileIds * test: Add boundary cases for agent file access authorization - Agent with no tool_resources denies all access (fail-closed) - Files across multiple resource types are all reachable - Author + isDelete: true still scopes to attached files only	2026-03-15 18:54:34 -04:00
Danny Avila	bcf45519bd	🪪 fix: Enforce VIEW ACL on Agent Edge References at Write and Runtime (#12246) ... * 🛡️ fix: Enforce ACL checks on handoff edge and added-convo agent loading Edge-linked agents and added-convo agents were fetched by ID via getAgent without verifying the requesting user's access permissions. This allowed an authenticated user to reference another user's private agent in edges or addedConvo and have it initialized at runtime. Add checkPermission(VIEW) gate in processAgent before initializing any handoff agent, and in processAddedConvo for non-ephemeral added agents. Unauthorized agents are logged and added to skippedAgentIds so orphaned-edge filtering removes them cleanly. * 🛡️ fix: Validate edge agent access at agent create/update time Reject agent create/update requests that reference agents in edges the requesting user cannot VIEW. This provides early feedback and prevents storing unauthorized agent references as defense-in-depth alongside the runtime ACL gate in processAgent. Add collectEdgeAgentIds utility to extract all unique agent IDs from an edge array, and validateEdgeAgentAccess helper in the v1 handler. * 🧪 test: Improve ACL gate test coverage and correctness - Add processAgent ACL gate tests for initializeClient (skip/allow handoff agents) - Fix addedConvo.spec.js to mock loadAddedAgent directly instead of getAgent - Seed permMap with ownedAgent VIEW bits in v1.spec.js update-403 test * 🧹 chore: Remove redundant addedConvo ACL gate (now in middleware) PR #12243 moved the addedConvo agent ACL check upstream into canAccessAgentFromBody middleware, making the runtime check in processAddedConvo and its spec redundant. * 🧪 test: Rewrite processAgent ACL test with real DB and minimal mocking Replace heavy mock-based test (12 mocks, Providers.XAI crash) with MongoMemoryServer-backed integration test that exercises real getAgent, checkPermission, and AclEntry — only external I/O (initializeAgent, ToolService, AgentClient) remains mocked. Load edge utilities directly from packages/api/src/agents/edges to sidestep the config.ts barrel. * 🧪 fix: Use requireActual spread for @librechat/agents and @librechat/api mocks The Providers.XAI crash was caused by mocking @librechat/agents with a minimal replacement object, breaking the @librechat/api initialization chain. Match the established pattern from client.test.js and recordCollectedUsage.spec.js: spread jest.requireActual for both packages, overriding only the functions under test.	2026-03-15 18:08:57 -04:00
Danny Avila	8dc6d60750	🛡️ fix: Enforce MULTI_CONVO and agent ACL checks on addedConvo (#12243) ... * 🛡️ fix: Enforce MULTI_CONVO and agent ACL checks on addedConvo addedConvo.agent_id was passed through to loadAddedAgent without any permission check, enabling an authenticated user to load and execute another user's private agent via the parallel multi-convo feature. The middleware now chains a checkAddedConvoAccess gate after the primary agent check: when req.body.addedConvo is present it verifies the user has MULTI_CONVO:USE role permission, and when the addedConvo agent_id is a real (non-ephemeral) agent it runs the same canAccessResource ACL check used for the primary agent. * refactor: Harden addedConvo middleware and avoid duplicate agent fetch - Convert checkAddedConvoAccess to curried factory matching Express middleware signature: (requiredPermission) => (req, res, next) - Call checkPermission directly for the addedConvo agent instead of routing through canAccessResource's tempReq pattern; this avoids orphaning the resolved agent document and enables caching it on req.resolvedAddedAgent for downstream loadAddedAgent - Update loadAddedAgent to use req.resolvedAddedAgent when available, eliminating a duplicate getAgent DB call per chat request - Validate addedConvo is a plain object and agent_id is a string before passing to isEphemeralAgentId (prevents TypeError on object injection, returns 400-equivalent early exit instead of 500) - Fix JSDoc: "VIEW access" → "same permission as primary agent", add @param/@returns to helpers, restore @example on factory - Fix redundant return await in resolveAgentIdFromBody * test: Add canAccessAgentFromBody spec covering IDOR fix 26 integration tests using MongoMemoryServer with real models, ACL entries, and PermissionService — no mocks for core logic. Covered paths: - Factory validation (requiredPermission type check) - Primary agent: missing agent_id, ephemeral, non-agents endpoint - addedConvo absent / invalid shape (string, array, object injection) - MULTI_CONVO:USE gate: denied, missing role, ADMIN bypass - Agent resource ACL: no ACL → 403, insufficient bits → 403, nonexistent agent → 404, valid ACL → next + cached on req - End-to-end: both real agents, primary denied short-circuits, ephemeral primary + real addedConvo	2026-03-15 17:12:45 -04:00
Danny Avila	0c27ad2d55	🛡️ refactor: Scope Action Mutations by Parent Resource Ownership (#12237) ... * 🛡️ fix: Scope action mutations by parent resource ownership Prevent cross-tenant action overwrites by validating that an existing action's agent_id/assistant_id matches the URL parameter before allowing updates or deletes. Without this, a user with EDIT access on their own agent could reference a foreign action_id to hijack another agent's action record. * 🛡️ fix: Harden action ownership checks and scope write filters - Remove && short-circuit that bypassed the guard when agent_id or assistant_id was falsy (e.g. assistant-owned actions have no agent_id, so the check was skipped entirely on the agents route). - Include agent_id / assistant_id in the updateAction and deleteAction query filters so the DB write itself enforces ownership atomically. - Log a warning when deleteAction returns null (silent no-op from data-integrity mismatch). * 📝 docs: Update Action model JSDoc to reflect scoped query params * ✅ test: Add Action ownership scoping tests Cover update, delete, and cross-type protection scenarios using MongoMemoryServer to verify that scoped query filters (agent_id, assistant_id) prevent cross-tenant overwrites and deletions at the database level. * 🛡️ fix: Scope updateAction filter in agent duplication handler * 🐛 fix: Use action metadata domain instead of action_id when duplicating agent actions The duplicate handler was splitting `action.action_id` by `actionDelimiter` to extract the domain, but `action_id` is a bare nanoid that doesn't contain the delimiter. This produced malformed entries in the duplicated agent's actions array (nanoid_action_newNanoid instead of domain_action_newNanoid). The domain is available on `action.metadata.domain`. * ✅ test: Add integration tests for agent duplication action handling Uses MongoMemoryServer with real Agent and Action models to verify: - Duplicated actions use metadata.domain (not action_id) for the agent actions array entries - Sensitive metadata fields are stripped from duplicated actions - Original action documents are not modified	2026-03-15 10:19:29 -04:00
Danny Avila	7bc793b18d	🌊 fix: Prevent Buffered Event Duplication on SSE Resume Connections (#12225) ... * fix: skipBufferReplay for job resume connections - Introduced a new option `skipBufferReplay` in the `subscribe` method of `GenerationJobManagerClass` to prevent duplication of events when resuming a connection. - Updated the logic to conditionally skip replaying buffered events if a sync event has already been sent, enhancing the efficiency of event handling during reconnections. - Added integration tests to verify the correct behavior of the new option, ensuring that no buffered events are replayed when `skipBufferReplay` is true, while still allowing for normal replay behavior when false. * refactor: Update GenerationJobManager to handle sync events more efficiently - Modified the `subscribe` method to utilize a new `skipBufferReplay` option, allowing for the prevention of duplicate events during resume connections. - Enhanced the logic in the `chat/stream` route to conditionally skip replaying buffered events if a sync event has already been sent, improving event handling efficiency. - Updated integration tests to verify the correct behavior of the new option, ensuring that no buffered events are replayed when `skipBufferReplay` is true, while maintaining normal replay behavior when false. * test: Enhance GenerationJobManager integration tests for Redis mode - Updated integration tests to conditionally run based on the USE_REDIS environment variable, allowing for better control over Redis-related tests. - Refactored test descriptions to utilize a dynamic `describeRedis` function, improving clarity and organization of tests related to Redis functionality. - Removed redundant checks for Redis availability within individual tests, streamlining the test logic and enhancing readability. * fix: sync handler state for new messages on resume The sync event's else branch (new response message) was missing resetContentHandler() and syncStepMessage() calls, leaving stale handler state that caused subsequent deltas to build on partial content instead of the synced aggregatedContent. * feat: atomic subscribeWithResume to close resume event gap Replaces separate getResumeState() + subscribe() calls with a single subscribeWithResume() that atomically drains earlyEventBuffer between the resume snapshot and the subscribe. In in-memory mode, drained events are returned as pendingEvents for the client to replay after sync. In Redis mode, pendingEvents is empty since chunks are already persisted. The route handler now uses the atomic method for resume connections and extracted shared SSE write helpers to reduce duplication. The client replays any pendingEvents through the existing step/content handlers after applying aggregatedContent from the sync payload. * fix: only capture gap events in subscribeWithResume, not pre-snapshot buffer The previous implementation drained the entire earlyEventBuffer into pendingEvents, but pre-snapshot events are already reflected in aggregatedContent. Replaying them re-introduced the duplication bug through a different vector. Now records buffer length before getResumeState() and slices from that index, so only events arriving during the async gap are returned as pendingEvents. Also: - Handle pendingEvents when resumeState is null (replay directly) - Hoist duplicate test helpers to shared scope - Remove redundant writableEnded guard in onDone	2026-03-14 10:54:26 -04:00
Danny Avila	cbdc6f6060	📦 chore: Bump NPM Audit Packages (#12227) ... * 🔧 chore: Update file-type dependency to version 21.3.2 in package-lock.json and package.json - Upgraded the "file-type" package from version 18.7.0 to 21.3.2 to ensure compatibility with the latest features and security updates. - Added new dependencies related to the updated "file-type" package, enhancing functionality and performance. * 🔧 chore: Upgrade undici dependency to version 7.24.1 in package-lock.json and package.json - Updated the "undici" package from version 7.18.2 to 7.24.1 across multiple package files to ensure compatibility with the latest features and security updates. * 🔧 chore: Upgrade yauzl dependency to version 3.2.1 in package-lock.json - Updated the "yauzl" package from version 3.2.0 to 3.2.1 to incorporate the latest features and security updates. * 🔧 chore: Upgrade hono dependency to version 4.12.7 in package-lock.json - Updated the "hono" package from version 4.12.5 to 4.12.7 to incorporate the latest features and security updates.	2026-03-14 03:36:03 -04:00
Danny Avila	f67bbb2bc5	🧹 fix: Sanitize Artifact Filenames in Code Execution Output (#12222) ... * fix: sanitize artifact filenames to prevent path traversal in code output * test: Mock sanitizeFilename function in process.spec.js to return the original filename - Added a mock implementation for the `sanitizeFilename` function in the `process.spec.js` test file to return the original filename, ensuring that tests can run without altering the filename during the testing process. * fix: use path.relative for traversal check, sanitize all filenames, add security logging - Replace startsWith with path.relative pattern in saveLocalBuffer, consistent with deleteLocalFile and getLocalFileStream in the same file - Hoist sanitizeFilename call before the image/non-image branch so both code paths store the sanitized name in MongoDB - Log a warning when sanitizeFilename mutates a filename (potential traversal) - Log a specific warning when saveLocalBuffer throws a traversal error, so security events are distinguishable from generic network errors in the catch * test: improve traversal test coverage and remove mock reimplementation - Remove partial sanitizeFilename reimplementation from process-traversal tests; use controlled mock returns to verify processCodeOutput wiring instead - Add test for image branch sanitization - Use mkdtempSync for test isolation in crud-traversal to avoid parallel worker collisions - Add prefix-collision bypass test case (../user10/evil vs user1 directory) * fix: use path.relative in isValidPath to prevent prefix-collision bypass Pre-existing startsWith check without path separator had the same class of prefix-collision vulnerability fixed in saveLocalBuffer.	2026-03-14 03:09:26 -04:00
Danny Avila	35a35dc2e9	📏 refactor: Add File Size Limits to Conversation Imports (#12221) ... * fix: add file size limits to conversation import multer instance * fix: address review findings for conversation import file size limits * fix: use local jest.mock for data-schemas instead of global moduleNameMapper The global @librechat/data-schemas mock in jest.config.js only provided logger, breaking all tests that depend on createModels from the same package. Replace with a virtual jest.mock scoped to the import spec file. * fix: move import to top of file, pre-compute upload middleware, assert logger.warn in tests * refactor: move resolveImportMaxFileSize to packages/api New backend logic belongs in packages/api as TypeScript. Delete the api/server/utils/import/limits.js wrapper and import directly from @librechat/api in convos.js and importConversations.js. Resolver unit tests move to packages/api; the api/ spec retains only multer behavior tests. * chore: rename importLimits to import * fix: stale type reference and mock isolation in import tests Update typeof import path from '../importLimits' to '../import' after the rename. Clear mockLogger.warn in beforeEach to prevent cross-test accumulation. * fix: add resolveImportMaxFileSize to @librechat/api mock in convos.spec.js * fix: resolve jest.mock hoisting issue in import tests jest.mock factories are hoisted above const declarations, so the mockLogger reference was undefined at factory evaluation time. Use a direct import of the mocked logger module instead. * fix: remove virtual flag from data-schemas mock for CI compatibility virtual: true prevents the mock from intercepting the real module in CI where @librechat/data-schemas is built, causing import.ts to use the real logger while the test asserts against the mock.	2026-03-14 03:06:29 -04:00
Danny Avila	c6982dc180	🛡️ fix: Agent Permission Check on Image Upload Route (#12219) ... * fix: add agent permission check to image upload route * refactor: remove unused SystemRoles import and format test file for clarity * fix: address review findings for image upload agent permission check * refactor: move agent upload auth logic to TypeScript in packages/api Extract pure authorization logic from agentPermCheck.js into checkAgentUploadAuth() in packages/api/src/files/agentUploadAuth.ts. The function returns a structured result ({ allowed, status, error }) instead of writing HTTP responses directly, eliminating the dual responsibility and confusing sentinel return value. The JS wrapper in /api is now a thin adapter that translates the result to HTTP. * test: rewrite image upload permission tests as integration tests Replace mock-heavy images-agent-perm.spec.js with integration tests using MongoMemoryServer, real models, and real PermissionService. Follows the established pattern in files.agents.test.js. Moves test to sibling location (images.agents.test.js) matching backend convention. Adds temp file cleanup assertions on 403/404 responses and covers message_file exemption paths (boolean true, string "true", false). * fix: widen AgentUploadAuthDeps types to accept ObjectId from Mongoose The injected getAgent returns Mongoose documents where _id and author are Types.ObjectId at runtime, not string. Widen the DI interface to accept string | Types.ObjectId for _id, author, and resourceId so the contract accurately reflects real callers. * chore: move agent upload auth into files/agents/ subdirectory * refactor: delete agentPermCheck.js wrapper, move verifyAgentUploadPermission to packages/api The /api-only dependencies (getAgent, checkPermission) are now passed as object-field params from the route call sites. Both images.js and files.js import verifyAgentUploadPermission from @librechat/api and inject the deps directly, eliminating the intermediate JS wrapper. * style: fix import type ordering in agent upload auth * fix: prevent token TTL race in MCPTokenStorage.storeTokens When expires_in is provided, use it directly instead of round-tripping through Date arithmetic. The previous code computed accessTokenExpiry as a Date, then after an async encryptV2 call, recomputed expiresIn by subtracting Date.now(). On loaded CI runners the elapsed time caused Math.floor to truncate to 0, triggering the 1-year fallback and making the token appear permanently valid — so refresh never fired.	2026-03-14 02:57:56 -04:00
Danny Avila	71a3b48504	🔑 fix: Require OTP Verification for 2FA Re-Enrollment and Backup Code Regeneration (#12223) ... * fix: require OTP verification for 2FA re-enrollment and backup code regeneration * fix: require OTP verification for account deletion when 2FA is enabled * refactor: Improve code formatting and readability in TwoFactorController and UserController - Reformatted code in TwoFactorController and UserController for better readability by aligning parameters and breaking long lines. - Updated test cases in deleteUser.spec.js and TwoFactorController.spec.js to enhance clarity by formatting object parameters consistently. * refactor: Consolidate OTP and backup code verification logic in TwoFactorController and UserController - Introduced a new `verifyOTPOrBackupCode` function to streamline the verification process for TOTP tokens and backup codes across multiple controllers. - Updated the `enable2FA`, `disable2FA`, and `deleteUserController` methods to utilize the new verification function, enhancing code reusability and readability. - Adjusted related tests to reflect the changes in verification logic, ensuring consistent behavior across different scenarios. - Improved error handling and response messages for verification failures, providing clearer feedback to users. * chore: linting * refactor: Update BackupCodesItem component to enhance OTP verification logic - Consolidated OTP input handling by moving the 2FA verification UI logic to a more consistent location within the component. - Improved the state management for OTP readiness, ensuring the regenerate button is only enabled when the OTP is ready. - Cleaned up imports by removing redundant type imports, enhancing code clarity and maintainability. * chore: lint * fix: stage 2FA re-enrollment in pending fields to prevent disarmament window enable2FA now writes to pendingTotpSecret/pendingBackupCodes instead of overwriting the live fields. confirm2FA performs the atomic swap only after the new TOTP code is verified. If the user abandons mid-flow, their existing 2FA remains active and intact.	2026-03-14 01:51:31 -04:00
Danny Avila	189cdf581d	🔐 fix: Add User Filter to Message Deletion (#12220) ... * fix: add user filter to message deletion to prevent IDOR * refactor: streamline DELETE request syntax in messages-delete test - Simplified the DELETE request syntax in the messages-delete.spec.js test file by combining multiple lines into a single line for improved readability. This change enhances the clarity of the test code without altering its functionality. * fix: address review findings for message deletion IDOR fix * fix: add user filter to message deletion in conversation tests - Included a user filter in the message deletion test to ensure proper handling of user-specific deletions, enhancing the accuracy of the test case and preventing potential IDOR vulnerabilities. * chore: lint	2026-03-13 23:42:37 -04:00

Danny Avila	fa9e1b228a	🪪 fix: MCP API Responses and OAuth Validation (#12217) ... * 🔒 fix: Validate MCP Configs in Server Responses * 🔒 fix: Enhance OAuth URL Validation in MCPOAuthHandler - Introduced validation for OAuth URLs to ensure they do not target private or internal addresses, enhancing security against SSRF attacks. - Updated the OAuth flow to validate both authorization and token URLs before use, ensuring compliance with security standards. - Refactored redirect URI handling to streamline the OAuth client registration process. - Added comprehensive error handling for invalid URLs, improving robustness in OAuth interactions. * 🔒 feat: Implement Permission Checks for MCP Server Management - Added permission checkers for MCP server usage and creation, enhancing access control. - Updated routes for reinitializing MCP servers and retrieving authentication values to include these permission checks, ensuring only authorized users can access these functionalities. - Refactored existing permission logic to improve clarity and maintainability. * 🔒 fix: Enhance MCP Server Response Validation and Redaction - Updated MCP route tests to use `toMatchObject` for better validation of server response structures, ensuring consistency in expected properties. - Refactored the `redactServerSecrets` function to streamline the removal of sensitive information, ensuring that user-sourced API keys are properly redacted while retaining their source. - Improved OAuth security tests to validate rejection of private URLs across multiple endpoints, enhancing protection against SSRF vulnerabilities. - Added comprehensive tests for the `redactServerSecrets` function to ensure proper handling of various server configurations, reinforcing security measures. * chore: eslint * 🔒 fix: Enhance OAuth Server URL Validation in MCPOAuthHandler - Added validation for discovered authorization server URLs to ensure they meet security standards. - Improved logging to provide clearer insights when an authorization server is found from resource metadata. - Refactored the handling of authorization server URLs to enhance robustness against potential security vulnerabilities. * 🔒 test: Bypass SSRF validation for MCP OAuth Flow tests - Mocked SSRF validation functions to allow tests to use real local HTTP servers, facilitating more accurate testing of the MCP OAuth flow. - Updated test setup to ensure compatibility with the new mocking strategy, enhancing the reliability of the tests. * 🔒 fix: Add Validation for OAuth Metadata Endpoints in MCPOAuthHandler - Implemented checks for the presence and validity of registration and token endpoints in the OAuth metadata, enhancing security by ensuring that these URLs are properly validated before use. - Improved error handling and logging to provide better insights during the OAuth metadata processing, reinforcing the robustness of the OAuth flow. * 🔒 refactor: Simplify MCP Auth Values Endpoint Logic - Removed redundant permission checks for accessing the MCP server resource in the auth-values endpoint, streamlining the request handling process. - Consolidated error handling and response structure for improved clarity and maintainability. - Enhanced logging for better insights during the authentication value checks, reinforcing the robustness of the endpoint. * 🔒 test: Refactor LeaderElection Integration Tests for Improved Cleanup - Moved Redis key cleanup to the beforeEach hook to ensure a clean state before each test. - Enhanced afterEach logic to handle instance resignations and Redis key deletion more robustly, improving test reliability and maintainability.	2026-03-13 23:18:56 -04:00
Danny Avila	f32907cd36	🔏 fix: MCP Server URL Schema Validation (#12204) ... * fix: MCP server configuration validation and schema - Added tests to reject URLs containing environment variable references for SSE, streamable-http, and websocket types in the MCP routes. - Introduced a new schema in the data provider to ensure user input URLs do not resolve environment variables, enhancing security against potential leaks. - Updated existing MCP server user input schema to utilize the new validation logic, ensuring consistent handling of user-supplied URLs across the application. * fix: MCP URL validation to reject env variable references - Updated tests to ensure that URLs for SSE, streamable-http, and websocket types containing environment variable patterns are rejected, improving security against potential leaks. - Refactored the MCP server user input schema to enforce stricter validation rules, preventing the resolution of environment variables in user-supplied URLs. - Introduced new test cases for various URL types to validate the rejection logic, ensuring consistent handling across the application. * test: Enhance MCPServerUserInputSchema tests for environment variable handling - Introduced new test cases to validate the prevention of environment variable exfiltration through user input URLs in the MCPServerUserInputSchema. - Updated existing tests to confirm that URLs containing environment variable patterns are correctly resolved or rejected, improving security against potential leaks. - Refactored test structure to better organize environment variable handling scenarios, ensuring comprehensive coverage of edge cases.	2026-03-12 23:19:31 -04:00
Danny Avila	3ddf62c8e5	🫙 fix: Force MeiliSearch Full Sync on Empty Index State (#12202) ... * fix: meili index sync with unindexed documents - Updated `performSync` function to force a full sync when a fresh MeiliSearch index is detected, even if the number of unindexed messages or convos is below the sync threshold. - Added logging to indicate when a fresh index is detected and a full sync is initiated. - Introduced new tests to validate the behavior of the sync logic under various conditions, ensuring proper handling of fresh indexes and threshold scenarios. This change improves the reliability of the synchronization process, ensuring that all documents are indexed correctly when starting with a fresh index. * refactor: update sync logic for unindexed documents in MeiliSearch - Renamed variables in `performSync` to improve clarity, changing `freshIndex` to `noneIndexed` for better understanding of the sync condition. - Adjusted the logic to ensure a full sync is forced when no messages or conversations are marked as indexed, even if below the sync threshold. - Updated related tests to reflect the new logging messages and conditions, enhancing the accuracy of the sync threshold logic. This change improves the readability and reliability of the synchronization process, ensuring all documents are indexed correctly when starting with a fresh index. * fix: enhance MeiliSearch index creation error handling - Updated the `mongoMeili` function to improve logging and error handling during index creation in MeiliSearch. - Added handling for `MeiliSearchTimeOutError` to log a warning when index creation times out. - Enhanced logging to differentiate between successful index creation and specific failure reasons, including cases where the index already exists. - Improved debug logging for index creation tasks to provide clearer insights into the process.

Danny Avila	fcb344da47	🛂 fix: MCP OAuth Race Conditions, CSRF Fallback, and Token Expiry Handling (#12171) ... * fix: Implement race conditions in MCP OAuth flow - Added connection mutex to coalesce concurrent `getUserConnection` calls, preventing multiple simultaneous attempts. - Enhanced flow state management to retry once when a flow state is missing, improving resilience against race conditions. - Introduced `ReauthenticationRequiredError` for better error handling when access tokens are expired or missing. - Updated tests to cover new race condition scenarios and ensure proper handling of OAuth flows. * fix: Stale PENDING flow detection and OAuth URL re-issuance PENDING flows in handleOAuthRequired now check createdAt age — flows older than 2 minutes are treated as stale and replaced instead of joined. Fixes the case where a leftover PENDING flow from a previous session blocks new OAuth initiation. authorizationUrl is now stored in MCPOAuthFlowMetadata so that when a second caller joins an active PENDING flow (e.g., the SSE-emitting path in ToolService), it can re-issue the URL to the user via oauthStart. * fix: CSRF fallback via active PENDING flow in OAuth callback When the OAuth callback arrives without CSRF or session cookies (common in the chat/SSE flow where cookies can't be set on streaming responses), fall back to validating that a PENDING flow exists for the flowId. This is safe because the flow was created server-side after JWT authentication and the authorization code is PKCE-protected. * test: Extract shared OAuth test server helpers Move MockKeyv, getFreePort, trackSockets, and createOAuthMCPServer into a shared helpers/oauthTestServer module. Enhance the test server with refresh token support, token rotation, metadata discovery, and dynamic client registration endpoints. Add InMemoryTokenStore for token storage tests.

Refactored token expiration checks in `MCPConnectionFactory` to utilize the new normalization function, ensuring consistent behavior. - Added a comprehensive test suite for OAuth callback CSRF fallback logic, validating the handling of PENDING flows and their staleness. - Enhanced existing tests to cover new expiration normalization logic and ensure robust flow state management. * test: Add CSRF fallback tests for active PENDING flows in MCP OAuth - Introduced new tests to validate CSRF fallback behavior when a fresh PENDING flow exists without cookies, ensuring successful OAuth callback handling. - Added scenarios to reject requests when no PENDING flow exists, when only a COMPLETED flow is present, and when a PENDING flow is stale, enhancing the robustness of flow state management. - Improved overall test coverage for OAuth callback logic, reinforcing the handling of CSRF validation failures. * chore: imports order * refactor: Update UserConnectionManager to conditionally manage pending connections - Modified the logic in `UserConnectionManager` to only set pending connections if `forceNew` is false, preventing unnecessary overwrites. - Adjusted the cleanup process to ensure pending connections are only deleted when not forced, enhancing connection management efficiency. * refactor: MCP OAuth flow state management - Introduced a new method `storeStateMapping` in `MCPOAuthHandler` to securely map the OAuth state parameter to the flow ID, improving callback resolution and security against forgery. - Updated the OAuth initiation and callback handling in `mcp.js` to utilize the new state mapping functionality, ensuring robust flow management. - Refactored `MCPConnectionFactory` to store state mappings during flow initialization, enhancing the integrity of the OAuth process. - Adjusted comments to clarify the purpose of state parameters in authorization URLs, reinforcing code readability. * refactor: MCPConnection with OAuth recovery handling - Added `oauthRecovery` flag to manage OAuth recovery state during connection attempts. - Introduced `decrementCycleCount` method to reduce the circuit breaker's cycle count upon successful reconnection after OAuth recovery. - Updated connection logic to reset the `oauthRecovery` flag after handling OAuth, improving state management and connection reliability. * chore: Add debug logging for OAuth recovery cycle count decrement - Introduced a debug log statement in the `MCPConnection` class to track the decrement of the cycle count after a successful reconnection during OAuth recovery. - This enhancement improves observability and aids in troubleshooting connection issues related to OAuth recovery. * test: Add OAuth recovery cycle management tests -

Improved test coverage for OAuth reconnect scenarios, ensuring reliable behavior under various conditions. * feat: Implement circuit breaker configuration in MCP - Added circuit breaker settings to `.env.example` for max cycles, cycle window, and cooldown duration. - Refactored `MCPConnection` to utilize the new configuration values from `mcpConfig`, enhancing circuit breaker management. - Improved code maintainability by centralizing circuit breaker parameters in the configuration file. * refactor: Update decrementCycleCount method for circuit breaker management - Changed the visibility of the `decrementCycleCount` method in `MCPConnection` from private to public static, allowing it to be called with a server name parameter. - Updated calls to `decrementCycleCount` in `MCPConnectionFactory` to use the new static method, improving clarity and consistency in circuit breaker management during connection failures and OAuth recovery. - Enhanced the handling of circuit breaker state by ensuring the method checks for the existence of the circuit breaker before decrementing the cycle count. * refactor: cycle count decrement on tool listing failure - Added a call to `MCPConnection.decrementCycleCount` in the `MCPConnectionFactory` to handle cases where unauthenticated tool listing fails, improving circuit breaker management. - This change ensures that the cycle count is decremented appropriately, maintaining the integrity of the connection recovery process. * refactor: Update circuit breaker configuration and logic - Enhanced circuit breaker settings in `.env.example` to include new parameters for failed rounds and backoff strategies. - Refactored `MCPConnection` to utilize the updated configuration values from `mcpConfig`, improving circuit breaker management. - Updated tests to reflect changes in circuit breaker logic, ensuring accurate validation of connection behavior under rapid reconnect scenarios. * feat: Implement state mapping deletion in MCP flow management -

This adds toolkit expansion so child tools are included in definitions, and resolves child tool names to their parent toolkit constructor at runtime. * chore: Remove toolkit flag from gemini_image_gen gemini_image_gen only has a single tool, so it is not a true toolkit. * refactor: Address review findings for toolkit expansion - Guard against duplicate constructor calls when parent and child tools are both in the tools array (Finding 2) - Consolidate image tool descriptions/schemas — registry now derives from toolkit objects (oaiToolkit, geminiToolkit) instead of duplicating them, so env var overrides are respected everywhere (Finding 5) - Move toolkitExpansion/toolkitParent to toolkits/mapping.ts with immutable types (Findings 6, 9) - Add tests for toolkit expansion, deduplication, and mapping invariants (Finding 1) - Fix log format to quote each tool individually (Finding 8) * fix: Correct toolkit constructor lookup to store under requested tool name The previous dedup guard stored the factory under toolKey (parent name) instead of tool (requested name), causing the promise loop to miss child tools like image_edit_oai. Now stores under both the parent key (for dedup) and the requested name (for lookup), with a memoized factory to ensure the constructor runs only once.	2026-03-04 09:28:20 -05:00

Danny Avila	b18915a96b	🚪 fix: Complete OIDC RP-Initiated Logout With id_token_hint and Redirect Race Fix (#12024) ... * fix: complete OIDC logout implementation The OIDC logout feature added in #5626 was incomplete: 1. Backend: Missing id_token_hint/client_id parameters required by the RP-Initiated Logout spec. Keycloak 18+ rejects logout without these. 2. Frontend: The logout redirect URL was passed through isSafeRedirect() which rejects all absolute URLs. The redirect was silently dropped. Backend: Add id_token_hint (preferred) or client_id (fallback) to the logout URL for OIDC spec compliance. Frontend: Use window.location.replace() for logout redirects from the backend, bypassing isSafeRedirect() which was designed for user-input validation. Fixes #5506 * fix: accept undefined in setTokenHeader to properly clear Authorization header When token is undefined, delete the Authorization header instead of setting it to "Bearer undefined". Removes the @ts-ignore workaround in AuthContext. * fix: skip axios 401 refresh when Authorization header is cleared When the Authorization header has been removed (e.g. during logout), the response interceptor now skips the token refresh flow. This prevents a successful refresh from canceling an in-progress OIDC external redirect via window.location.replace(). * fix: guard against undefined OPENID_CLIENT_ID in logout URL Prevent literal "client_id=undefined" in the OIDC end-session URL when OPENID_CLIENT_ID is not set. Log a warning when neither id_token_hint nor client_id is available. * fix: prevent race condition canceling OIDC logout redirect The logout mutation wrapper's cleanup (clearStates, removeQueries) triggers re-renders and 401s on in-flight requests. The axios interceptor would refresh the token successfully, firing dispatchTokenUpdatedEvent which cancels the window.location.replace() navigation to the IdP's end_session_endpoint. Fix: - Clear Authorization header synchronously before redirect so the axios interceptor skips refresh for post-logout 401s - Add isExternalRedirectRef to suppress silentRefresh and useEffect side effects during the redirect - Add JSDoc explaining why isSafeRedirect is bypassed * test: add LogoutController and AuthContext logout test coverage LogoutController.spec.js (13 tests): - id_token_hint from session and cookie fallback - client_id fallback, including undefined OPENID_CLIENT_ID guard - Disabled endpoint, missing issuer, non-OpenID user - post_logout_redirect_uri (custom and default) - Missing OpenID config and end_session_endpoint - Error handling and cookie clearing AuthContext.spec.tsx (3 tests): - OIDC redirect calls window.location.replace + setTokenHeader - Non-redirect logout path - Logout error handling * test: add coverage for setTokenHeader, axios interceptor guard, and silentRefresh suppression headers-helpers.spec.ts (3 tests): - Sets Authorization header with Bearer token - Deletes Authorization header when called with undefined - No-op when clearing an already absent header request-interceptor.spec.ts (2 tests): - Skips refresh when Authorization header is cleared (the race fix) - Attempts refresh when Authorization header is present AuthContext.spec.tsx (1 new test): - Verifies silentRefresh is not triggered after OIDC redirect * test: enhance request-interceptor tests with adapter restoration and refresh verification - Store the original axios adapter before tests and restore it after all tests to prevent side effects. - Add verification for the refresh endpoint call in the interceptor tests to ensure correct behavior during token refresh attempts. * test: enhance AuthContext tests with live rendering and improved logout error handling - Introduced a new `renderProviderLive` function to facilitate testing with silentRefresh. - Updated tests to use the live rendering function, ensuring accurate simulation of authentication behavior. - Enhanced logout error handling test to verify that auth state is cleared without external redirects. * test: update LogoutController tests for OpenID config error handling - Renamed test suite to clarify that it handles cases when OpenID config is not available. - Modified test to check for error thrown by getOpenIdConfig instead of returning null, ensuring proper logging of the error message. * refactor: improve OpenID config error handling in LogoutController - Simplified error handling for OpenID configuration retrieval by using a try-catch block. - Updated logging to provide clearer messages when the OpenID config is unavailable. - Ensured that the end session endpoint is only accessed if the OpenID config is successfully retrieved. --------- Co-authored-by: cloudspinner <stijn.tastenhoye@gmail.com>	2026-03-02 21:34:13 -05:00
Jón Levy	f7ac449ca4	🔌 fix: Resolve MCP OAuth flow state race condition (#11941) ... * 🔌 fix: Resolve MCP OAuth flow state race condition The OAuth callback arrives before the flow state is stored because `createFlow()` returns a long-running Promise that only resolves on flow COMPLETION, not when the initial PENDING state is persisted. Calling it fire-and-forget with `.catch(() => {})` meant the redirect happened before the state existed, causing "Flow state not found" errors. Changes: - Add `initFlow()` to FlowStateManager that stores PENDING state and returns immediately, decoupling state persistence from monitoring - Await `initFlow()` before emitting the OAuth redirect so the callback always finds existing state - Keep `createFlow()` in the background for monitoring, but log warnings instead of silently swallowing errors - Increase FLOWS cache TTL from 3 minutes to 10 minutes to give users more time to complete OAuth consent screens Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * 🔌 refactor: Revert FLOWS cache TTL change The race condition fix (initFlow) is sufficient on its own. TTL configurability should be a separate enhancement via librechat.yaml mcpSettings rather than a hardcoded increase. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * 🔌 fix: Address PR review — restore FLOWS TTL, fix blocking-path race, clean up dead args - Restore FLOWS cache TTL to 10 minutes (was silently dropped back to 3) - Add initFlow before oauthStart in blocking handleOAuthRequired path to guarantee state persistence before any redirect - Pass {} to createFlow metadata arg (dead after initFlow writes state) - Downgrade background monitor .catch from logger.warn to logger.debug - Replace process.nextTick with Promise.resolve in test (correct semantics) - Add initFlow TTL assertion test - Add blocking-path ordering test (initFlow → oauthStart → createFlow) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-02 19:27:36 -05:00

Danny Avila	e1e204d6cf	🧮 refactor: Bulk Transactions & Balance Updates for Token Spending (#11996) ... * refactor: transaction handling by integrating pricing and bulk write operations - Updated `recordCollectedUsage` to accept pricing functions and bulk write operations, improving transaction management. - Refactored `AgentClient` and related controllers to utilize the new transaction handling capabilities, ensuring better performance and accuracy in token spending. - Added tests to validate the new functionality, ensuring correct behavior for both standard and bulk transaction paths. - Introduced a new `transactions.ts` file to encapsulate transaction-related logic and types, enhancing code organization and maintainability. * chore: reorganize imports in agents client controller - Moved `getMultiplier` and `getCacheMultiplier` imports to maintain consistency and clarity in the import structure. - Removed duplicate import of `updateBalance` and `bulkInsertTransactions`, streamlining the code for better readability. * refactor: add TransactionData type and CANCEL_RATE constant to data-schemas Establishes a single source of truth for the transaction document shape and the incomplete-context billing rate constant, both consumed by packages/api and api/. * refactor: use proper types in data-schemas transaction methods - Replace `as unknown as { tokenCredits }` with `lean<IBalance>()` - Use `TransactionData[]` instead of `Record<string, unknown>[]` for bulkInsertTransactions parameter - Add JSDoc noting insertMany bypasses document middleware - Remove orphan section comment in methods/index.ts * refactor: use shared types in transactions.ts, fix bulk write logic - Import CANCEL_RATE from data-schemas instead of local duplicate - Import TransactionData from data-schemas for PreparedEntry/BulkWriteDeps - Use tilde alias for EndpointTokenConfig import - Pass valueKey through to getMultiplier - Only sum tokenValue for balance-enabled docs in bulkWriteTransactions - Consolidate two loops into single-pass map * refactor: remove duplicate updateBalance from Transaction.js Import updateBalance from ~/models (sourced from data-schemas) instead of maintaining a second copy. Also import CANCEL_RATE from data-schemas and remove the Balance model import (no longer needed directly). * fix: test real spendCollectedUsage instead of IIFE replica Export spendCollectedUsage from abortMiddleware.js and rewrite the test file to import and test the actual function. Previously the tests ran against a hand-written replica that could silently diverge from the real implementation. * test: add transactions.spec.ts and restore regression comments Add 22 direct unit tests for transactions.ts financial logic covering prepareTokenSpend, prepareStructuredTokenSpend, bulkWriteTransactions, CANCEL_RATE paths, NaN guards, disabled transactions, zero tokens, cache multipliers, and balance-enabled filtering. Restore critical regression documentation comments in recordCollectedUsage.spec.js explaining which production bugs the tests guard against. * fix: widen setValues type to include lastRefill The UpdateBalanceParams.setValues type was Partial<Pick<IBalance, 'tokenCredits'>> which excluded lastRefill — used by createAutoRefillTransaction. Widen to also pick 'lastRefill'. * test: use real MongoDB for bulkWriteTransactions tests Replace mock-based bulkWriteTransactions tests with real DB tests using MongoMemoryServer. Pure function tests (prepareTokenSpend, prepareStructuredTokenSpend) remain mock-based since they don't touch DB. Add end-to-end integration tests that verify the full prepare → bulk write → DB state pipeline with real Transaction and Balance models. * chore: update @librechat/agents dependency to version 3.1.54 in package-lock.json and related package.json files * test: add bulk path parity tests proving identical DB outcomes Three test suites proving the bulk path (prepareTokenSpend/ prepareStructuredTokenSpend + bulkWriteTransactions) produces numerically identical results to the legacy path for all scenarios: - usage.bulk-parity.spec.ts: mirrors all legacy recordCollectedUsage tests; asserts same return values and verifies metadata fields on the insertMany docs match what spendTokens args would carry - transactions.bulk-parity.spec.ts: real-DB tests using actual getMultiplier/getCacheMultiplier pricing functions; asserts exact tokenValue, rate, rawAmount and balance deductions for standard tokens, structured/cache tokens, CANCEL_RATE, premium pricing, multi-entry batches, and edge cases (NaN, zero, disabled) - Transaction.spec.js: adds describe('Bulk path parity') that mirrors 7 key legacy tests via recordCollectedUsage + bulk deps against real MongoDB, asserting same balance deductions and doc counts * refactor: update llmConfig structure to use modelKwargs for reasoning effort Refactor the llmConfig in getOpenAILLMConfig to store reasoning effort within modelKwargs instead of directly on llmConfig. This change ensures consistency in the configuration structure and improves clarity in the handling of reasoning properties in the tests. * test: update performance checks in processAssistantMessage tests Revise the performance assertions in the processAssistantMessage tests to ensure that each message processing time remains under 100ms, addressing potential ReDoS vulnerabilities. This change enhances the reliability of the tests by focusing on maximum processing time rather than relative ratios. * test: fill parity test gaps — model fallback, abort context, structured edge cases - usage.bulk-parity: add undefined model fallback test - transactions.bulk-parity: add abort context test (txns inserted, balance unchanged when balance not passed), fix readTokens type cast - Transaction.spec: add 3 missing mirrors — balance disabled with transactions enabled, structured transactions disabled, structured balance disabled * fix: deduct balance before inserting transactions to prevent orphaned docs Swap the order in bulkWriteTransactions: updateBalance runs before insertMany. If updateBalance fails (after exhausting retries), no transaction documents are written — avoiding the inconsistent state where transactions exist in MongoDB with no corresponding balance deduction. * chore: import order * test: update config.spec.ts for OpenRouter reasoning in modelKwargs Same fix as llm.spec.ts — OpenRouter reasoning is now passed via modelKwargs instead of llmConfig.reasoning directly.	2026-03-01 12:26:36 -05:00

Improve warning messages to name the fallback chain explicitly and distinguish missing vs. non-string claim values. Fix the domain-block error log to record the resolved identifier rather than userinfo.email, which was misleading when OPENID_EMAIL_CLAIM resolved to a different field (e.g. upn). Fix a latent test defect in openIdJwtStrategy.spec.js where the ~/server/services/Config mock exported getCustomConfig instead of getAppConfig, the symbol actually consumed by openidStrategy.js. Add refreshController tests covering the OPENID_EMAIL_CLAIM paths, which were previously untested despite being a stated fix target. Expand JWT strategy tests with null-payload, empty/whitespace OPENID_EMAIL_CLAIM, migration-via-preferred_username, and call-order assertions for the findUser lookup sequence. * test(auth): enhance AuthController and openIdJwtStrategy tests for openidId updates Added a new test in AuthController to verify that the openidId is updated correctly when a migration is triggered during the refresh process.
