Django 4.2.14 release notes
===========================

*July 9, 2024*

Django 4.2.14 fixes two security issues with severity "moderate" and two
security issues with severity "low" in 4.2.13.

CVE-2024-38875: Potential denial-of-service vulnerability in ``django.utils.html.urlize()``
===========================================================================================

:tfilter:`urlize` and :tfilter:`urlizetrunc` were subject to a potential
denial-of-service attack via certain inputs with a very large number of
brackets.

CVE-2024-39329: Username enumeration through timing difference for users with unusable passwords
================================================================================================

The :meth:`~django.contrib.auth.backends.ModelBackend.authenticate()` method
allowed remote attackers to enumerate users via a timing attack involving login
requests for users with unusable passwords.

CVE-2024-39330: Potential directory-traversal via ``Storage.save()``
====================================================================

Derived classes of the :class:`~django.core.files.storage.Storage` base class
which override :meth:`generate_filename()
<django.core.files.storage.Storage.generate_filename()>` without replicating
the file path validations existing in the parent class, allowed for potential
directory-traversal via certain inputs when calling :meth:`save()
<django.core.files.storage.Storage.save()>`.

Built-in ``Storage`` sub-classes were not affected by this vulnerability.
