# Django 6.0.5 release notes

May 5, 2026

Django 6.0.5 fixes three security issues with severity "low" and several bugs in 6.0.4.

## CVE-2026-5766: Potential denial-of-service vulnerability in ASGI requests via file upload limit bypass

ASGI requests with a missing or understated `Content-Length` header could 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`.

This issue has severity "low" according to the Django security policy.

## CVE-2026-35192: Session fixation via public cached pages and `SESSION_SAVE_EVERY_REQUEST`

Response headers did not vary on cookies if a session was not modified, but `SESSION_SAVE_EVERY_REQUEST` was `True`. A remote attacker could steal a user's session after that user visits a cached public page.

This issue has severity "low" according to the Django security policy.

## CVE-2026-6907: Potential exposure of private data due to incorrect handling of `Vary: *` in `UpdateCacheMiddleware`

Previously, `UpdateCacheMiddleware` would erroneously cache requests where the `Vary` header contained an asterisk (`'*'`). This could lead to private data being stored and served.

This issue has severity "low" according to the Django security policy.

## 漏洞修复

- Fixed a misplaced `</div>` in the `django/contrib/admin/templates/admin/change_list.html` template added in Django 6.0 that could be problematic when overriding the `pagination` block (#37029).

- Fixed a bug in Django 6.0 where deprecation warnings incorrectly skipped lines from third-party packages prefixed with "django" (#37067).
