Django 5.0.10 release notes
===========================

*December 4, 2024*

Django 5.0.10 fixes one security issue with severity "high" and one security
issue with severity "moderate" in 5.0.9.

CVE-2024-53907: Denial-of-service possibility in ``strip_tags()``
=================================================================

:func:`~django.utils.html.strip_tags` would be extremely slow to evaluate
certain inputs containing large sequences of nested incomplete HTML entities.
The ``strip_tags()`` method is used to implement the corresponding
:tfilter:`striptags` template filter, which was thus also vulnerable.

``strip_tags()`` now has an upper limit of recursive calls to ``HTMLParser``
before raising a :exc:`.SuspiciousOperation` exception.

Remember that absolutely NO guarantee is provided about the results of
``strip_tags()`` being HTML safe. So NEVER mark safe the result of a
``strip_tags()`` call without escaping it first, for example with
:func:`django.utils.html.escape`.

CVE-2024-53908: Potential SQL injection via ``HasKey(lhs, rhs)`` on Oracle
==========================================================================

Direct usage of the ``django.db.models.fields.json.HasKey`` lookup on Oracle
was subject to SQL injection if untrusted data was used as a ``lhs`` value.

Applications that use the :lookup:`has_key <jsonfield.has_key>` lookup through
the ``__`` syntax are unaffected.
