Django 5.1.9 release notes
|
|
==========================
|
|
|
|
*Expected May 7, 2025*
|
|
|
|
Django 5.1.9 fixes a security issue with severity "moderate", a data loss bug,
|
|
and a regression in 5.1.8.
|
|
|
|
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 5.1.8, introduced when fixing :cve:`2025-26699`,
|
|
where the :tfilter:`wordwrap` template filter did not preserve empty lines
|
|
between paragraphs after wrapping text (:ticket:`36341`).
