+# 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.
+
+### 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.
+
+### For more information
+
+If you have any questions or comments about this advisory:
