CVE-2026-6907CVE-2026-5766CVE-2026-35192

Summary

Several security issues were fixed in Django.

Details

It was discovered that Django did not vary cached response headers on cookies when sessions were not modified while SESSION_SAVE_EVERY_REQUEST was enabled. A remote attacker could possibly use this issue to steal a user's session. (CVE-2026-35192) Kyle Agronick and Jacob Walls discovered that Django incorrectly handled ASGI requests with missing or understated Content-Length header values. A remote attacker could possibly use this issue to cause Django to use excessive resources, leading to a denial of service. (CVE-2026-5766) Ahmad Sadeddin discovered that Django UpdateCacheMiddleware incorrectly cached requests where the Vary header contained an asterisk. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-6907)
