Django 4.2.21 release notes
|
|
===========================
|
|
|
|
*May 7, 2025*
|
|
|
|
Django 4.2.21 fixes a security issue with severity "moderate", a data loss bug,
|
|
and a regression in 4.2.20.
|
|
|
|
This release was built using an upgraded :pypi:`setuptools`, producing
|
|
filenames compliant with :pep:`491` and :pep:`625` and thus addressing a PyPI
|
|
warning about non-compliant distribution filenames. This change only affects
|
|
the Django packaging process and does not impact Django's behavior.
|
|
|
|
CVE-2025-32873: Denial-of-service possibility in ``strip_tags()``
|
|
=================================================================
|
|
|
|
:func:`~django.utils.html.strip_tags` would be slow to evaluate certain inputs
|
|
containing large sequences of incomplete HTML tags. This function is used to
|
|
implement the :tfilter:`striptags` template filter, which was thus also
|
|
vulnerable.
|
|
|
|
:func:`~django.utils.html.strip_tags` now raises a :exc:`.SuspiciousOperation`
|
|
exception if it encounters an unusually large number of unclosed opening tags.
|
|
|
|
Bugfixes
|
|
========
|
|
|
|
* Fixed a data corruption possibility in ``file_move_safe()`` when
|
|
``allow_overwrite=True``, where leftover content from a previously larger
|
|
file could remain after overwriting with a smaller one due to lack of
|
|
truncation (:ticket:`36298`).
|
|
|
|
* Fixed a regression in Django 4.2.20, introduced when fixing
|
|
:cve:`2025-26699`, where the :tfilter:`wordwrap` template filter did not
|
|
preserve empty lines between paragraphs after wrapping text
|
|
(:ticket:`36341`).
