NVD Description

Note: Versions mentioned in the description apply only to the upstream py3.13-django-bin package and not the py3.13-django-bin package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6. django.middleware.cache.UpdateCacheMiddleware in Django does not match Cache-Control response directives case-insensitively, which allows remote attackers to read responses that were incorrectly cached because their Cache-Control directives used uppercase or mixed-case values. 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 Ahmed Badawe for reporting this issue.
