Danny Avila	530b401e7b	📜 feat: Implement System Grants for Capability-Based Authorization (#11896) ... * feat: Implement System Grants for Role-Based Capabilities - Added a new `systemGrant` model and associated methods to manage role-based capabilities within the application. - Introduced middleware functions `hasCapability` and `requireCapability` to check user permissions based on their roles. - Updated the database seeding process to include system grants for the ADMIN role, ensuring all necessary capabilities are assigned on startup. - Enhanced type definitions and schemas to support the new system grant functionality, improving overall type safety and clarity in the codebase. * test: Add unit tests for capabilities middleware and system grant methods - Introduced comprehensive unit tests for the capabilities middleware, including `hasCapability` and `requireCapability`, ensuring proper permission checks based on user roles. - Added tests for the `SystemGrant` methods, verifying the seeding of system grants, capability granting, and revocation processes. - Enhanced test coverage for edge cases, including idempotency of grant operations and handling of unexpected errors in middleware. - Utilized mocks for database interactions to isolate tests and improve reliability. * refactor: Transition to Capability-Based Access Control - Replaced role-based access checks with capability-based checks across various middleware and routes, enhancing permission management. - Introduced `hasCapability` and `requireCapability` functions to streamline capability verification for user actions. - Updated relevant routes and middleware to utilize the new capability system, ensuring consistent permission enforcement. - Enhanced type definitions and added tests for the new capability functions, improving overall code reliability and maintainability. * test: Enhance capability-based access tests for ADMIN role - Updated tests to reflect the new capability-based access control, specifically for the ADMIN role. - Modified test descriptions to clarify that users with the MANAGE_AGENTS capability can bypass permission checks. - Seeded capabilities for the ADMIN role in multiple test files to ensure consistent permission checks across different routes and middleware. - Improved overall test coverage for capability verification, ensuring robust permission management. * test: Update capability tests for MCP server access - Renamed test to reflect the correct capability for bypassing permission checks, changing from MANAGE_AGENTS to MANAGE_MCP_SERVERS. - Updated seeding of capabilities for the ADMIN role to align with the new capability structure. - Ensured consistency in capability definitions across tests and middleware for improved permission management. * feat: Add hasConfigCapability for enhanced config access control - Introduced `hasConfigCapability` function to check user permissions for managing or reading specific config sections. - Updated middleware to export the new capability function, ensuring consistent access control across the application. - Enhanced unit tests to cover various scenarios for the new capability, improving overall test coverage and reliability. * fix: Update tenantId filter in createSystemGrantMethods - Added a condition to set tenantId filter to { $exists: false } when tenantId is null, ensuring proper handling of cases where tenantId is not provided. - This change improves the robustness of the system grant methods by explicitly managing the absence of tenantId in the filter logic. * fix: account deletion capability check - Updated the `canDeleteAccount` middleware to ensure that the `hasManageUsers` capability check only occurs if a user is present, preventing potential errors when the user object is undefined. - This change improves the robustness of the account deletion logic by ensuring proper handling of user permissions. * refactor: Optimize seeding of system grants for ADMIN role - Replaced sequential capability granting with parallel execution using Promise.all in the seedSystemGrants function. - This change improves performance and efficiency during the initialization of system grants, ensuring all capabilities are granted concurrently. * refactor: Simplify systemGrantSchema index definition - Removed the sparse option from the unique index on principalType, principalId, capability, and tenantId in the systemGrantSchema. - This change streamlines the index definition, potentially improving query performance and clarity in the schema design. * refactor: Reorganize role capability check in roles route - Moved the capability check for reading roles to occur after parsing the roleName, improving code clarity and structure. - This change ensures that the authorization logic is consistently applied before fetching role details, enhancing overall permission management. * refactor: Remove unused ISystemGrant interface from systemCapabilities.ts - Deleted the ISystemGrant interface as it was no longer needed, streamlining the code and improving clarity. - This change helps reduce clutter in the file and focuses on relevant capabilities for the system. * refactor: Migrate SystemCapabilities to data-schemas - Replaced imports of SystemCapabilities from 'librechat-data-provider' with imports from '@librechat/data-schemas' across multiple files. - This change centralizes the management of system capabilities, improving code organization and maintainability. * refactor: Update account deletion middleware and capability checks - Modified the `canDeleteAccount` middleware to ensure that the account deletion permission is only granted to users with the `MANAGE_USERS` capability, improving security and clarity in permission management. - Enhanced error logging for unauthorized account deletion attempts, providing better insights into permission issues. - Updated the `capabilities.ts` file to ensure consistent handling of user authentication checks, improving robustness in capability verification. - Refined type definitions in `systemGrant.ts` and `systemGrantMethods.ts` to utilize the `PrincipalType` enum, enhancing type safety and code clarity. * refactor: Extract principal ID normalization into a separate function - Introduced `normalizePrincipalId` function to streamline the normalization of principal IDs based on their type, enhancing code clarity and reusability. - Updated references in `createSystemGrantMethods` to utilize the new normalization function, improving maintainability and reducing code duplication. * test: Add unit tests for principalId normalization in systemGrant - Introduced tests for the `grantCapability`, `revokeCapability`, and `getCapabilitiesForPrincipal` methods to verify correct handling of principalId normalization between string and ObjectId formats. - Enhanced the `capabilities.ts` middleware to utilize the `PrincipalType` enum for improved type safety. - Added a new utility function `normalizePrincipalId` to streamline principal ID normalization logic, ensuring consistent behavior across the application. * feat: Introduce capability implications and enhance system grant methods - Added `CapabilityImplications` to define relationships between broader and implied capabilities, allowing for more intuitive permission checks. - Updated `createSystemGrantMethods` to expand capability queries to include implied capabilities, improving authorization logic. - Enhanced `systemGrantSchema` to include an `expiresAt` field for future TTL enforcement of grants, and added validation to ensure `tenantId` is not set to null. - Documented authorization requirements for prompt group and prompt deletion methods to clarify access control expectations. * test: Add unit tests for canDeleteAccount middleware - Introduced unit tests for the `canDeleteAccount` middleware to verify account deletion permissions based on user roles and capabilities. - Covered scenarios for both allowed and blocked account deletions, including checks for ADMIN users with the `MANAGE_USERS` capability and handling of undefined user cases. - Enhanced test structure to ensure clarity and maintainability of permission checks in the middleware. * fix: Add principalType enum validation to SystemGrant schema Without enum validation, any string value was accepted for principalType and silently stored. Invalid documents would never match capability queries, creating phantom grants impossible to diagnose without raw DB inspection. All other ACL models in the codebase validate this field. * fix: Replace seedSystemGrants Promise.all with bulkWrite for concurrency safety When two server instances start simultaneously (K8s rolling deploy, PM2 cluster), both call seedSystemGrants. With Promise.all + findOneAndUpdate upsert, both instances may attempt to insert the same documents, causing E11000 duplicate key errors that crash server startup. bulkWrite with ordered:false handles concurrent upserts gracefully and reduces 17 individual round trips to a single network call. The returned documents (previously discarded) are no longer fetched. * perf: Add AsyncLocalStorage per-request cache for capability checks Every hasCapability call previously required 2 DB round trips (getUserPrincipals + SystemGrant.exists) — replacing what were O(1) string comparisons. Routes like patchPromptGroup triggered this twice, and hasConfigCapability's fallback path resolved principals twice. This adds a per-request AsyncLocalStorage cache that: - Caches resolved principals (same for all checks within one request) - Caches capability check results (same user+cap = same answer) - Automatically scoped to request lifetime (no stale grants) - Falls through to DB when no store exists (background jobs, tests) - Requires no signature changes to hasCapability The capabilityContextMiddleware is registered at the app level before all routes, initializing a fresh store per request. * fix: Add error handling for inline hasCapability calls canDeleteAccount, fetchAssistants, and validateAuthor all call hasCapability without try-catch. These were previously O(1) string comparisons that could never throw. Now they hit the database and can fail on connection timeout or transient errors. Wrap each call in try-catch, defaulting to deny (false) on error. This ensures a DB hiccup returns a clean 403 instead of an unhandled 500 with a stack trace. * test: Add canDeleteAccount DB-error resilience test Tests that hasCapability rejection (e.g., DB timeout) results in a clean 403 rather than an unhandled exception. Validates the error handling added in the previous commit. * refactor: Use barrel import for hasCapability in validateAuthor Import from ~/server/middleware barrel instead of directly from ~/server/middleware/roles/capabilities for consistency with other non-middleware consumers. Files within the middleware barrel itself must continue using direct imports to avoid circular requires. * refactor: Remove misleading pre('save') hook from SystemGrant schema The pre('save') hook normalized principalId for USER/GROUP principals, but the primary write path (grantCapability) uses findOneAndUpdate — which does not trigger save hooks. The normalization was already handled explicitly in grantCapability itself. The hook created a false impression of schema-level enforcement that only covered save()/create() paths. Replace with a comment documenting that all writes must go through grantCapability. * feat: Add READ_ASSISTANTS capability to complete manage/read pair Every other managed resource had a paired READ_X / MANAGE_X capability except assistants. This adds READ_ASSISTANTS and registers the MANAGE_ASSISTANTS → READ_ASSISTANTS implication in CapabilityImplications, enabling future read-only assistant visibility grants. * chore: Reorder systemGrant methods for clarity Moved hasCapabilityForPrincipals to a more logical position in the returned object of createSystemGrantMethods, improving code readability. This change also maintains the inclusion of seedSystemGrants in the export, ensuring all necessary methods are available. * fix: Wrap seedSystemGrants in try-catch to avoid blocking startup Seeding capabilities is idempotent and will succeed on the next restart. A transient DB error during seeding should not prevent the server from starting — log the error and continue. * refactor: Improve capability check efficiency and add audit logging Move hasCapability calls after cheap early-exits in validateAuthor and fetchAssistants so the DB check only runs when its result matters. Add logger.debug on every capability bypass grant across all 7 call sites for auditability, and log errors in catch blocks instead of silently swallowing them. * test: Add integration tests for AsyncLocalStorage capability caching Exercises the full vertical — ALS context, generateCapabilityCheck, real getUserPrincipals, real hasCapabilityForPrincipals, real MongoDB via MongoMemoryServer. Covers per-request caching, cross-context isolation, concurrent request isolation, negative caching, capability implications, tenant scoping, group-based grants, and requireCapability middleware. * test: Add systemGrant data-layer and ALS edge-case integration tests systemGrant.spec.ts (51 tests): Full integration tests for all systemGrant methods against real MongoDB — grant/revoke lifecycle, principalId normalization (string→ObjectId for USER/GROUP, string for ROLE), capability implications (both directions), tenant scoping, schema validation (null tenantId, invalid enum, required fields, unique compound index). capabilities.integration.spec.ts (27 tests): Adds ALS edge cases — missing context degrades gracefully with no caching (background jobs, child processes), nested middleware creates independent inner context, optional-chaining safety when store is undefined, mid-request grant changes are invisible due to result caching, requireCapability works without ALS, and interleaved concurrent contexts maintain isolation. * fix: Add worker thread guards to capability ALS usage Detect when hasCapability or capabilityContextMiddleware is called from a worker thread (where ALS context does not propagate from the parent). hasCapability logs a warn-once per factory instance; the middleware logs an error since mounting Express middleware in a worker is likely a misconfiguration. Both continue to function correctly — the guard is observability, not a hard block. * fix: Include tenantId in ALS principal cache key for tenant isolation The principal cache key was user.id:user.role, which would reuse cached principals across tenants for the same user within a request. When getUserPrincipals gains tenant-scoped group resolution, principals from tenant-a would incorrectly serve tenant-b checks. Changed to user.id:user.role:user.tenantId to prevent cross-tenant cache hits. Adds integration test proving separate principal lookups per tenantId. * test: Remove redundant mocked capabilities.spec.js The JS wrapper test (7 tests, all mocked) is a strict subset of capabilities.integration.spec.ts (28 tests, real MongoDB). Every scenario it covered — hasCapability true/false, tenantId passthrough, requireCapability 403/500, error handling — is tested with higher fidelity in the integration suite. * test: Replace mocked canDeleteAccount tests with real MongoDB integration Remove hasCapability mock — tests now exercise the full capability chain against real MongoDB (getUserPrincipals, hasCapabilityForPrincipals, SystemGrant collection). Only mocks remaining are logger and cache. Adds new coverage: admin role without grant is blocked, user-level grant bypasses deletion restriction, null user handling. * test: Add comprehensive tests for ACL entry management and user group methods Introduces new tests for `deleteAclEntries`, `bulkWriteAclEntries`, and `findPublicResourceIds` in `aclEntry.spec.ts`, ensuring proper functionality for deleting and bulk managing ACL entries. Additionally, enhances `userGroup.spec.ts` with tests for finding groups by ID and name pattern, including external ID matching and source filtering. These changes improve coverage and validate the integrity of ACL and user group operations against real MongoDB interactions. * refactor: Update capability checks and logging for better clarity and error handling Replaced `MANAGE_USERS` with `ACCESS_ADMIN` in the `canDeleteAccount` middleware and related tests to align with updated permission structure. Enhanced logging in various middleware functions to use `logger.warn` for capability check failures, providing clearer error messages. Additionally, refactored capability checks in the `patchPromptGroup` and `validateAuthor` functions to improve readability and maintainability. This commit also includes adjustments to the `systemGrant` methods to implement retry logic for transient failures during capability seeding, ensuring robustness in the face of database errors. * refactor: Enhance logging and retry logic in seedSystemGrants method Updated the logging format in the seedSystemGrants method to include error messages for better clarity. Improved the retry mechanism by explicitly mocking multiple failures in tests, ensuring robust error handling during transient database issues. Additionally, refined imports in the systemGrant schema for better type management. * refactor: Consolidate imports in canDeleteAccount middleware Merged logger and SystemCapabilities imports from the data-schemas module into a single line for improved readability and maintainability of the code. This change streamlines the import statements in the canDeleteAccount middleware. * test: Enhance systemGrant tests for error handling and capability validation Added tests to the systemGrant methods to handle various error scenarios, including E11000 race conditions, invalid ObjectId strings for USER and GROUP principals, and invalid capability strings. These enhancements improve the robustness of the capability granting and revoking logic, ensuring proper error propagation and validation of inputs. * fix: Wrap hasCapability calls in deny-by-default try-catch at remaining sites canAccessResource, files.js, and roles.js all had hasCapability inside outer try-catch blocks that returned 500 on DB failure instead of falling through to the regular ACL check. This contradicts the deny-by-default pattern used everywhere else. Also removes raw error.message from the roles.js 500 response to prevent internal host/connection info leaking to clients. * fix: Normalize user ID in canDeleteAccount before passing to hasCapability requireCapability normalizes req.user.id via _id?.toString() fallback, but canDeleteAccount passed raw req.user directly. If req.user.id is absent (some auth layers only populate _id), getUserPrincipals received undefined, silently returning empty principals and blocking the bypass. * fix: Harden systemGrant schema and type safety - Reject empty string tenantId in schema validator (was only blocking null; empty string silently orphaned documents) - Fix reverseImplications to use BaseSystemCapability[] instead of string[], preserving the narrow discriminated type - Document READ_ASSISTANTS as reserved/unenforced * test: Use fake timers for seedSystemGrants retry tests and add tenantId validation - Switch retry tests to jest.useFakeTimers() to eliminate 3+ seconds of real setTimeout delays per test run - Add regression test for empty-string tenantId rejection * docs: Add TODO(#12091) comments for tenant-scoped capability gaps In multi-tenant mode, platform-level grants (no tenantId) won't match tenant-scoped queries, breaking admin access. getUserPrincipals also returns cross-tenant group memberships. Both need fixes in #12091.	2026-03-10 23:15:54 -04:00

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. Refactor MCPOAuthRaceCondition.test.ts to import from shared helpers. * test: Add comprehensive MCP OAuth test modules MCPOAuthTokenStorage — 21 tests for storeTokens/getTokens with InMemoryTokenStore: encrypt/decrypt round-trips, expiry calculation, refresh callback wiring, ReauthenticationRequiredError paths. MCPOAuthFlow — 10 tests against real HTTP server: token refresh with stored client info, refresh token rotation, metadata discovery, dynamic client registration, full store/retrieve/expire/refresh lifecycle. MCPOAuthConnectionEvents — 5 tests for MCPConnection OAuth event cycle with real OAuth-gated MCP server: oauthRequired emission on 401, oauthHandled reconnection, oauthFailed rejection, token expiry detection. MCPOAuthTokenExpiry — 12 tests for the token expiry edge case: refresh success/failure paths, ReauthenticationRequiredError, PENDING flow CSRF fallback, authorizationUrl metadata storage, full re-auth cycle after refresh failure, concurrent expired token coalescing, stale PENDING flow detection. * test: Enhance MCP OAuth connection tests with cooldown reset Added a `beforeEach` hook to clear the cooldown for `MCPConnection` before each test, ensuring a clean state. Updated the race condition handling in the tests to properly clear the timeout, improving reliability in the event data retrieval process. * refactor: PENDING flow management and state recovery in MCP OAuth - Introduced a constant `PENDING_STALE_MS` to define the age threshold for PENDING flows, improving the handling of stale flows. - Updated the logic in `MCPConnectionFactory` and `FlowStateManager` to check the age of PENDING flows before joining or reusing them. - Modified the `completeFlow` method to return false when the flow state is deleted, ensuring graceful handling of race conditions. - Enhanced tests to validate the new behavior and ensure robustness against state recovery issues. * refactor: MCP OAuth flow management and testing - Updated the `completeFlow` method to log warnings when a tool flow state is not found during completion, improving error handling. - Introduced a new `normalizeExpiresAt` function to standardize expiration timestamp handling across the application. -

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

Juri Kuehn	13df8ed67c	🪪 feat: Add OPENID_EMAIL_CLAIM for Configurable OpenID User Identifier (#11699) ... * Allow setting the claim field to be used when OpenID login is configured * fix(openid): harden getOpenIdEmail and expand test coverage Guard against non-string claim values in getOpenIdEmail to prevent a TypeError crash in isEmailDomainAllowed when domain restrictions are configured. 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. Expanded the openIdJwtStrategy tests to include assertions for the updateUser function, ensuring that the correct parameters are passed when a user is found with a legacy email. This improves test coverage for OpenID-related functionality. --------- Co-authored-by: Danny Avila <danny@librechat.ai>	2026-02-25 22:31:03 -05:00

Danny Avila	b349f2f876	🪣 fix: Serve Fresh Presigned URLs on Agent List Cache Hits (#11902) ... * fix: serve cached presigned URLs on agent list cache hits On a cache hit the list endpoint was skipping the S3 refresh and returning whatever presigned URL was stored in MongoDB, which could be expired if the S3 URL TTL is shorter than the 30-minute cache window. refreshListAvatars now collects a urlCache map (agentId -> refreshed filepath) alongside its existing stats. The controller stores this map in the cache instead of a plain boolean and re-applies it to every paginated response, guaranteeing clients always receive a URL that was valid as of the last refresh rather than a potentially stale DB value. * fix: improve avatar refresh cache handling and logging Updated the avatar refresh logic to validate cached refresh data before proceeding with S3 URL updates. Enhanced logging to exclude sensitive `urlCache` details while still providing relevant statistics. Added error handling for cache invalidation during avatar updates to ensure robustness. * fix: update avatar refresh logic to clear urlCache on no change Modified the avatar refresh function to clear the urlCache when no new path is generated, ensuring that stale URLs are not retained. This change improves cache handling and aligns with the updated logic for avatar updates. * fix: enhance avatar refresh logic to handle legacy cache entries Updated the avatar refresh logic to accommodate legacy boolean cache entries, ensuring they are treated as cache misses and triggering a refresh. The cache now stores a structured `urlCache` map instead of a boolean, improving cache handling. Added tests to verify correct behavior for cache hits and misses, ensuring clients receive valid URLs based on the latest refresh.	2026-02-22 18:29:31 -05:00
Danny Avila	7ce898d6a0	📄 feat: Local Text Extraction for PDF, DOCX, and XLS/XLSX (#11900) ... * feat: Added "document parser" OCR strategy The document parser uses libraries to parse the text out of known document types. This lets LibreChat handle some complex document types without having to use a secondary service (like Mistral or standing up a RAG API server). To enable the document parser, set the ocr strategy to "document_parser" in librechat.yaml. We now support: - PDFs using pdfjs - DOCX using mammoth - XLS/XLSX using SheetJS (The associated packages were also added to the project.) * fix: applied Copilot code review suggestions - Properly calculate length of text based on UTF8. - Avoid issues with loading / blocking PDF parsing. * fix: improved docs on parseDocument() * chore: move to packages/api for TS support * refactor: make document processing the default ocr strategy - Introduced support for additional document types in the OCR strategy, including PDF, DOCX, and XLS/XLSX. - Updated the file upload handling to dynamically select the appropriate parsing strategy based on the file type. - Refactored the document parsing functions to use asynchronous imports for improved performance and maintainability. * test: add unit tests for processAgentFileUpload functionality - Introduced a new test suite for the processAgentFileUpload function in process.spec.js. - Implemented various test cases to validate OCR strategy selection based on file types, including PDF, DOCX, XLSX, and XLS. - Mocked dependencies to ensure isolated testing of file upload handling and strategy selection logic. - Enhanced coverage for scenarios involving OCR capability checks and default strategy fallbacks. * chore: update pdfjs-dist version and enhance document parsing tests - Bumped pdfjs-dist dependency to version 5.4.624 in both api and packages/api. - Refactored document parsing tests to use 'originalname' instead of 'filename' for file objects. - Added a new test case for parsing XLS files to improve coverage of document types supported by the parser. - Introduced a sample XLS file for testing purposes. * feat: enforce text size limit and improve OCR fallback handling in processAgentFileUpload - Added a check to ensure extracted text does not exceed the 15MB storage limit, throwing an error if it does. - Refactored the OCR handling logic to improve fallback behavior when the configured OCR fails, ensuring a more robust document processing flow. - Enhanced unit tests to cover scenarios for oversized text and fallback mechanisms, ensuring proper error handling and functionality. * fix: correct OCR URL construction in performOCR function - Updated the OCR URL construction to ensure it correctly appends '/ocr' to the base URL if not already present, improving the reliability of the OCR request. --------- Co-authored-by: Dan Lew <daniel@mightyacorn.com>	2026-02-22 14:22:45 -05:00
Danny Avila	7692fa837e	🪣 fix: S3 path-style URL support for MinIO, R2, and custom endpoints (#11894) ... * 🪣 fix: S3 path-style URL support for MinIO, R2, and custom endpoints `extractKeyFromS3Url` now uses `AWS_BUCKET_NAME` to automatically detect and strip the bucket prefix from path-style URLs, fixing `NoSuchKey` errors on URL refresh for any S3-compatible provider using a custom endpoint (MinIO, Cloudflare R2, Hetzner, Backblaze B2, etc.). No additional configuration required — the bucket name is already a required env var for S3 to function. `initializeS3` now passes `forcePathStyle: true` to the S3Client constructor when `AWS_FORCE_PATH_STYLE=true` is set. Required for providers whose SSL certificates do not support virtual-hosted-style bucket subdomains (e.g. Hetzner Object Storage), which previously caused 401 / SignatureDoesNotMatch on upload. Additional fixes: - Suppress error log noise in `extractKeyFromS3Url` catch path: plain S3 keys no longer log as errors, only inputs that start with http(s):// do - Fix test env var ordering so module-level constants pick up `AWS_BUCKET_NAME` and `S3_URL_EXPIRY_SECONDS` correctly before the module is required - Add missing `deleteRagFile` mock and assertion in `deleteFileFromS3` tests - Add `AWS_BUCKET_NAME` cleanup to `afterEach` to prevent cross-test pollution - Add `initializeS3` unit tests covering endpoint, forcePathStyle, credentials, singleton, and IRSA code paths - Document `AWS_FORCE_PATH_STYLE` in `.env.example`, `dotenv.mdx`, and `s3.mdx` * 🪣 fix: Enhance S3 URL key extraction for custom endpoints Updated `extractKeyFromS3Url` to support precise key extraction when using custom endpoints with path-style URLs. The logic now accounts for the `AWS_ENDPOINT_URL` and `AWS_FORCE_PATH_STYLE` environment variables, ensuring correct key handling for various S3-compatible providers. Added unit tests to verify the new functionality, including scenarios for endpoints with base paths. This improves compatibility and reduces potential errors when interacting with S3-like services.	2026-02-21 18:36:48 -05:00
Danny Avila	b7bfdfa8b2	🪪 fix: Handle Delimited String Role Claims in OpenID Strategy (#11892) ... * fix: handle space/comma-separated string roles claim in OpenID strategy When an OpenID provider returns the roles claim as a delimited string (e.g. "role1 role2 admin"), the previous code wrapped the entire string as a single array element, causing role checks to always fail even for users with the required role. Split string claims on whitespace and commas before comparison so that both array and delimited-string formats are handled correctly. Adds regression tests for space-separated, comma-separated, mixed, and non-matching delimited string cases. * fix: enhance admin role handling in OpenID strategy Updated the OpenID strategy to correctly handle admin roles specified as space-separated or comma-separated strings. The logic now splits these strings into an array for accurate role checks.
