How to fix?

Upgrade Ubuntu:22.04 python-django to version 2:3.2.12-2ubuntu1.27 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-django package and not the python-django package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 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.
