CVE-2025-29928Network attack vector

Continued access via cache-only session deletion

Published Mar 28, 2025 · Updated Mar 28, 2025

Session revocation failure in authentik before 2024.12.4 or 2025.2.3 allows remote authenticated users to retain deleted sessions. The AuthenticatedSession deletion signal and user-deactivation path always delete a cache key instead of invoking the configured database SessionStore. The flaw requires the non-default database session backend; deleting a session, deleting its user, or marking the user inactive leaves existing access intact.
