CVE-2026-8404

A flaw was found in Django. The django.middleware.cache.UpdateCacheMiddleware component does not correctly process Cache-Control response directives when they use uppercase or mixed-case values. This vulnerability allows a remote attacker to read responses that should not have been cached, leadin...

CVE-2026-35193
