CVE-2025-29928
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedauthentik is an open-source identity provider. Prior to versions 2024.12.4 and 2025.2.3, 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. authentik 2025.2.3 and 2024.12.4 fix this issue. 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.

2024.12.4 or 2025.2.3
- 1. Identify the current Authentik version by checking the running container or installation
- 2. If running a version < 2024.12.4 or >= 2025.2.0 but < 2025.2.3, plan for upgrade
- 3. Before upgrading, check the current session storage configuration in authentik (look for `AUTHENTIK_SESSION_DB` or similar configuration)
- 4. Create a backup of the current Authentik instance and database
- 5. Upgrade Authentik to version 2024.12.4 (for the 2024.x branch) OR version 2025.2.3 (for the 2025.x branch)
- 6. After upgrade, verify that session deletion now properly revokes sessions
- 7. As an alternative mitigation (if upgrade is not immediately possible): switch session storage from database to cache-based storage in the configuration, then restart Authentik - note this will invalidate all existing sessions and require users to re-authenticate
