Django Uses Cache Containing Sensitive Information
🔗 CVE IDs covered (1)
📋 Description
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 ('*'). 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 thanks Ahmad Sadeddin for reporting this issue.
