How to fix?

Upgrade Wolfi py3-django to version 6.0.5-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-django package and not the py3-django package as distributed by Wolfi. See How to fix? for Wolfi 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.
