FKIE_CVE-2025-7106

Vulnerability from fkie_nvd - Published: 2025-09-23 10:15 - Updated: 2026-10-11 20:10
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
danny-avila/librechat is affected by an authorization bypass vulnerability due to improper access control checks. The `checkAccess` function in `api/server/middleware/roles/access.js` uses `permissions.some()` to validate permissions, which incorrectly grants access if only one of multiple required permissions is present. This allows users with the 'USER' role to create agents despite having `CREATE: false` permission, as the check for `['USE', 'CREATE']` passes with just `USE: true`. This vulnerability affects other permission checks as well, such as `PROMPTS`. The issue is present in all versions prior to the fix.
