python3-django: An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6
CVE-2026-8404 is fixed in 3 products on 1 platform, first by python3-django 2:2.2.12-1ubuntu0.29+esm10, released June 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
