CVE-2025-7106

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.

Summary		(es) danny-avila/librechat está afectado por una vulnerabilidad de omisión de autorización debido a comprobaciones de control de acceso inadecuadas. La función 'checkAccess' en 'api/server/middleware/roles/access.js' usa 'permissions.some()' para validar permisos, lo que concede acceso incorrectamente si solo uno de los múltiples permisos requeridos está presente. Esto permite a los usuarios con el rol 'USER' crear agentes a pesar de tener el permiso 'CREATE: false', ya que la comprobación para '[\'USE\', \'CREATE\']' pasa con solo 'USE: true'. Esta vulnerabilidad afecta también a otras comprobaciones de permisos, como 'PROMPTS'. El problema está presente en todas las versiones anteriores a la corrección.
