Django 5.0.7 release notes
|
|
==========================
|
|
|
|
*July 9, 2024*
|
|
|
|
Django 5.0.7 fixes two security issues with severity "moderate", two security
|
|
issues with severity "low", and one bug in 5.0.6.
|
|
|
|
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.
|
|
|
|
CVE-2024-39614: Potential denial-of-service vulnerability in ``get_supported_language_variant()``
|
|
=================================================================================================
|
|
|
|
:meth:`~django.utils.translation.get_supported_language_variant` was subject to
|
|
a potential denial-of-service attack when used with very long strings
|
|
containing specific characters.
|
|
|
|
To mitigate this vulnerability, the language code provided to
|
|
:meth:`~django.utils.translation.get_supported_language_variant` is now parsed
|
|
up to a maximum length of 500 characters.
|
|
|
|
When the language code is over 500 characters, a :exc:`ValueError` will now be
|
|
raised if ``strict`` is ``True``, or if there is no generic variant and
|
|
``strict`` is ``False``.
|
|
|
|
Bugfixes
|
|
========
|
|
|
|
* Fixed a bug in Django 5.0 that caused a crash of ``Model.full_clean()`` on
|
|
unsaved model instances with a ``GeneratedField`` and certain defined
|
|
:attr:`Meta.constraints <django.db.models.Options.constraints>`
|
|
(:ticket:`35560`).
