CVE-2025-29928

Deletion of sessions did not revoke sessions when using database session storage​

Summary​

When authentik was configured to use the database for session storage (which is a non-default setting), deleting sessions via the Web Interface or the API would not revoke the session and the session holder would continue to have access to authentik.

This also affects automatic session deletion when a user is set to inactive or a user is deleted.

The session backend is configured via this setting; if this settings isn't set the sessions are stored in the cache (Redis), which is not affected by this.

Patches​

authentik 2025.2.3 and 2024.12.4 fix this issue.

Workarounds​

Switching to the cache-based session storage until the authentik instance can be upgraded is recommended. This will however also delete all existing sessions and users will have to re-authenticate.
