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. django.middleware.cache.UpdateCacheMiddleware erroneously caches requests where the Vary header contained an asterisk (&#39;*&#39;). This can lead to private data being stored and served. 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 Ahmad Sadeddin for reporting this issue.
