# Django 6.0.4 release notes

April 7, 2026

Django 6.0.4 fixes one security issue with severity "moderate", four security issues with severity "low", and several bugs in 6.0.3.

## CVE-2026-3902: ASGI header spoofing via underscore/hyphen conflation

`ASGIRequest` normalizes header names following WSGI conventions, mapping hyphens to underscores. As a result, even in configurations where reverse proxies carefully strip security-sensitive headers named with hyphens, such a header could be spoofed by supplying a header named with underscores.

Under WSGI, it is the responsibility of the server or proxy to avoid ambiguous mappings. (Django's `runserver` was patched in CVE 2015-0219.) But under ASGI, there is not the same uniform expectation, even if many proxies protect against this under default configuration (including `nginx` via `underscores_in_headers off;`).

Headers containing underscores are now ignored by `ASGIRequest`, matching the behavior of Daphne, the reference server for ASGI.

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

## CVE-2026-4277: Privilege abuse in `GenericInlineModelAdmin`

Add permissions on inline model instances were not validated on submission of forged `POST` data in `GenericInlineModelAdmin`.

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

## CVE-2026-4292: Privilege abuse in `ModelAdmin.list_editable`

Admin changelist forms using `list_editable` incorrectly allowed new instances to be created via forged `POST` data.

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

## CVE-2026-33033: Potential denial-of-service vulnerability in `MultiPartParser` via base64-encoded file upload

When using `django.http.multipartparser.MultiPartParser`, multipart uploads with `Content-Transfer-Encoding: base64` that include excessive whitespace may trigger repeated memory copying, potentially degrading performance.

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

## CVE-2026-33034: Potential denial-of-service vulnerability in ASGI requests via memory upload limit bypass

ASGI requests with a missing or understated `Content-Length` header could bypass the `DATA_UPLOAD_MAX_MEMORY_SIZE` limit when reading `HttpRequest.body`, potentially loading an unbounded request body into memory and causing service degradation.

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

## Perbaikan kesalahan

- Fixed a regression in Django 6.0 where `alogin()` and `alogout()` did not respectively set or clear `request.user` if it had already been materialized (e.g., by sync middleware) (#37017).

- Fixed a regression in Django 6.0 in admin forms where `RelatedFieldWidgetWrapper` incorrectly wrapped all widgets in a `<fieldset>` (#36949).

- Fixed a bug in Django 6.0 where the `fields.E348` system check did not detect name clashes between model managers and `related_name`s for non-self-referential relationships (#36973).
