Django Uses Persistent Cookies Containing Sensitive Information

CVE-2026-35192 / GHSA-7h2m-m8vj-598h

More information

Details

An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. Response headers do not vary on cookies if a session is not modified, but SESSION_SAVE_EVERY_REQUEST is True. A remote attacker can steal a user's session after that user visits a cached public page. 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 Cantina for reporting this issue.

Django Uses Cache Containing Sensitive Information

CVE-2026-6907 / GHSA-5hrc-gvxj-w55p

More information

Details

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.

Django has an Improper Handling of Length Parameter Inconsistency

CVE-2026-5766 / GHSA-w26r-rmm8-9c29

More information

Details

An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. ASGI requests with a missing or understated Content-Length header can bypass the FILE_UPLOAD_MAX_MEMORY_SIZE limit, potentially loading large files into memory and causing service degradation.

As a reminder, Django expects a limit to be configured at the web server level rather than solely relying on FILE_UPLOAD_MAX_MEMORY_SIZE. 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 Kyle Agronick for reporting this issue.

Django fails to prevent reuse of a partially-initialized connection after a failed STARTTLS handshake

CVE-2026-7666 / GHSA-mm6v-q8q9-pgcf

More information

Details

An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15.

django.core.mail.backends.smtp.EmailBackend in Django fails to prevent reuse of a partially-initialized connection after a failed STARTTLS handshake when fail_silently=True, which allows on-path network attackers to read email content via cleartext interception.

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 Kasper Dupont for reporting this issue.
