Django 5.2.8 release notes
|
|
==========================
|
|
|
|
*November 5, 2025*
|
|
|
|
Django 5.2.8 fixes one security issue with severity "high", one security issue
|
|
with severity "moderate", and several bugs in 5.2.7. It also adds compatibility
|
|
with Python 3.14.
|
|
|
|
CVE-2025-64458: Potential denial-of-service vulnerability in ``HttpResponseRedirect`` and ``HttpResponsePermanentRedirect`` on Windows
|
|
======================================================================================================================================
|
|
|
|
Python's :func:`NFKC normalization <python:unicodedata.normalize>` is slow on
|
|
Windows. As a consequence, :class:`~django.http.HttpResponseRedirect`,
|
|
:class:`~django.http.HttpResponsePermanentRedirect`, and the shortcut
|
|
:func:`redirect() <django.shortcuts.redirect>` were subject to a potential
|
|
denial-of-service attack via certain inputs with a very large number of Unicode
|
|
characters (follow up to :cve:`2025-27556`).
|
|
|
|
CVE-2025-64459: Potential SQL injection via ``_connector`` keyword argument
|
|
===========================================================================
|
|
|
|
:meth:`.QuerySet.filter`, :meth:`~.QuerySet.exclude`, :meth:`~.QuerySet.get`,
|
|
and :class:`~.Q` were subject to SQL injection using a suitably crafted
|
|
dictionary, with dictionary expansion, as the ``_connector`` argument.
|
|
|
|
Bugfixes
|
|
========
|
|
|
|
* Added compatibility for ``oracledb`` 3.4.0 (:ticket:`36646`).
|
|
|
|
* Fixed a bug in Django 5.2 where ``QuerySet.first()`` and ``QuerySet.last()``
|
|
raised an error on querysets performing aggregation that selected all fields
|
|
of a composite primary key.
|
|
|
|
* Fixed a bug in Django 5.2 where proxy models having a ``CompositePrimaryKey``
|
|
incorrectly raised a ``models.E042`` system check error.
