CVE-2026-41133 PUBLISHED

pyLoad has Stale Session Privilege After Role/Permission Change (Privilege Revocation Bypass)

Assigner: GitHub_M
Reserved: 17.04.2026 Published: 21.04.2026 Updated: 21.04.2026

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.
