Title
Teable before 2026-10-12T12-45-53Z.3331 Authorization Bypass via Folder Rename Endpoint
Summary
Teable before 2026-10-12T12-45-53Z.3331 contains an authorization bypass vulnerability that allows authenticated users to rename folders in other bases by supplying a foreign folderId. The PATCH /api/base/:baseId/node/folder/:folderId endpoint checks base|update only against the URL baseId, so attackers can rename folders in bases where they lack membership.

Title
phpMyFAQ 4.0.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta BOLA in FAQ Update via REST API
Summary
phpMyFAQ 4.0.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains a broken object-level authorization vulnerability in the PUT /api/v3.1/faq/update endpoint, which checks only the global edit_faq permission and does not verify access to the target FAQ. Authenticated users with edit_faq permission can supply the ID of a restricted FAQ they cannot view to modify its content, bypass moderation, and change its publication state.

phpMyFAQ 3.2.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta IDOR Leaks TOTP Secret via /admin/api/user/data
Summary
phpMyFAQ 3.2.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an insecure direct object reference vulnerability in GET /admin/api/user/data/{userId}, which returns any user's full faquserdata row, including the live TOTP secret, without a SuperAdmin or protected-target check. Delegated administrators with user-management rights can read a SuperAdmin's TOTP secret and generate valid codes to bypass two-factor authentication.

Title
MCP TypeScript SDK: Experimental tasks were not tied to the session that created them
Summary
MCP TypeScript SDK is the official TypeScript SDK for Model Context Protocol servers and clients. From version 1.24.0 to before version 1.32.0, the experimental tasks feature (taskStore) did not check which session created a task. Clients sharing one InMemoryTaskStore could list, read and cancel each other's tasks. This issue has been patched in version 1.32.0.

LingGuo-Drama through commit 8a6924a IDOR via /admin/v1/projects/:id API
Summary
LingGuo-Drama through commit 8a6924a contains an insecure direct object reference vulnerability that allows registered users to access other users' projects because projects.Get lacks an owner check. Self-registered attackers can iterate numeric IDs via GET, PUT and DELETE /admin/v1/projects/:id to read, overwrite, reassign or delete any user's short-drama projects.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
