NVD Description

Note: Versions mentioned in the description apply only to the upstream authentik-2026.2 package and not the authentik-2026.2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. Response headers do not vary on cookies if a session is not modified, but SESSION_SAVE_EVERY_REQUEST is True. A remote attacker can steal a user's session after that user visits a cached public page. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Cantina for reporting this issue.
