Django 6.0.2 release notes
==========================

*February 3, 2026*

Django 6.0.2 fixes three security issues with severity "high", two security
issues with severity "moderate", one security issue with severity "low", and
several bugs in 6.0.1.

CVE-2025-13473: Username enumeration through timing difference in mod_wsgi authentication handler
=================================================================================================

The ``django.contrib.auth.handlers.modwsgi.check_password()`` function for
:doc:`authentication via mod_wsgi</howto/deployment/wsgi/apache-auth>`
allowed remote attackers to enumerate users via a timing attack.

This issue has severity "low" according to the :ref:`Django security policy
<severity-levels>`.

CVE-2025-14550: Potential denial-of-service vulnerability via repeated headers when using ASGI
==============================================================================================

When receiving duplicates of a single header, ``ASGIRequest`` allowed a remote
attacker to cause a potential denial-of-service via a specifically created
request with multiple duplicate headers. The vulnerability resulted from
repeated string concatenation while combining repeated headers, which
produced super-linear computation resulting in service degradation or outage.

This issue has severity "moderate" according to the :ref:`Django security
policy <severity-levels>`.

CVE-2026-1207: Potential SQL injection via raster lookups on PostGIS
====================================================================

:ref:`Raster lookups <spatial-lookup-raster>` on GIS fields (only implemented
on PostGIS) were subject to SQL injection if untrusted data was used as a band
index.

As a reminder, all untrusted user input should be validated before use.

This issue has severity "high" according to the :ref:`Django security policy
<severity-levels>`.

CVE-2026-1285: Potential denial-of-service vulnerability in ``django.utils.text.Truncator`` HTML methods
========================================================================================================

``django.utils.text.Truncator.chars()`` and ``Truncator.words()`` methods (with
``html=True``) and the :tfilter:`truncatechars_html` and
:tfilter:`truncatewords_html` template filters were subject to a potential
denial-of-service attack via certain inputs with a large number of unmatched
HTML end tags, which could cause quadratic time complexity during HTML parsing.

This issue has severity "moderate" according to the :ref:`Django security
policy <severity-levels>`.

CVE-2026-1287: Potential SQL injection in column aliases via control characters
===============================================================================

:class:`.FilteredRelation` was subject to SQL injection in column aliases via
control characters, using a suitably crafted dictionary, with dictionary
expansion, as the ``**kwargs`` passed to :meth:`.QuerySet.annotate`,
:meth:`~.QuerySet.aggregate`, :meth:`~.QuerySet.extra`,
:meth:`~.QuerySet.values`, :meth:`~.QuerySet.values_list`, and
:meth:`~.QuerySet.alias`.

This issue has severity "high" according to the :ref:`Django security policy
<severity-levels>`.

CVE-2026-1312: Potential SQL injection via ``QuerySet.order_by`` and ``FilteredRelation``
=========================================================================================

:meth:`.QuerySet.order_by` was subject to SQL injection in column aliases
containing periods when the same alias was, using a suitably crafted
dictionary, with dictionary expansion, used in :class:`.FilteredRelation`.

This issue has severity "high" according to the :ref:`Django security policy
<severity-levels>`.

Bugfixes
========

* Fixed a visual regression in Django 6.0 that caused the admin filter sidebar
  to wrap below the changelist when filter elements contained long text
  (:ticket:`36850`).

* Fixed a visual regression in Django 6.0 for admin form fields grouped under a
  ``<fieldset>`` aligned horizontally (:ticket:`36788`).

* Fixed a regression in Django 6.0 where ``auto_now_add`` field values were not
  populated during ``INSERT`` operations, due to incorrect parameters passed to
  ``field.pre_save()`` (:ticket:`36847`).
