pyLoad has Stale Session Privilege After Role/Permission Change (Privilege Revocation Bypass)_CVE-2026-41133

{
    "lastseen": "",
    "description": "pyLoad is a free and open-source download manager written in Python. Versions up to and including 0.5.0b3.dev97 cache `role` and `permission` in the session at login and continues to authorize requests using these cached values, even after an admin changes the user's role/permissions in the database. As a result, an already logged-in user can keep old (revoked) privileges until logout/session expiry, enabling continued privileged actions. This is a core authorization/session-consistency issue and is not resolved by toggling an optional security feature. Commit e95804fb0d06cbb07d2ba380fc494d9ff89b68c1 contains a fix for the issue.",
