Changelog

3.2.13

===========================

*April 11, 2022*

Django 3.2.13 fixes two security issues with severity "high" in
3.2.12 and a regression in 3.2.4.

CVE-2022-28346: Potential SQL injection in ``QuerySet.annotate()``, ``aggregate()``, and ``extra()``
====================================================================================================

:meth:`.QuerySet.annotate`, :meth:`~.QuerySet.aggregate`, and
:meth:`~.QuerySet.extra` methods were subject to SQL injection in column
aliases, using a suitably crafted dictionary, with dictionary expansion, as the
``**kwargs`` passed to these methods.

CVE-2022-28347: Potential SQL injection via ``QuerySet.explain(**options)`` on PostgreSQL
=========================================================================================

:meth:`.QuerySet.explain` method was subject to SQL injection in option names,
using a suitably crafted dictionary, with dictionary expansion, as the
``**options`` argument.

Bugfixes
========

* Fixed a regression in Django 3.2.4 that caused the auto-reloader to no longer
detect changes when the ``DIRS`` option of the ``TEMPLATES`` setting
contained an empty string (:ticket:`33628`).
