  "title": "python3-django: An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6",
  "description": "An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6. \u0060django.middleware.cache.UpdateCacheMiddleware\u0060 in Django does not match \u0060Cache-Control\u0060 response directives case-insensitively, which allows remote attackers to read responses that were incorrectly cached because their \u0060Cache-Control\u0060 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.",
