Django 3.0.1 release notes
|
|
==========================
|
|
|
|
*December 18, 2019*
|
|
|
|
Django 3.0.1 fixes a security issue and several bugs in 3.0.
|
|
|
|
CVE-2019-19844: Potential account hijack via password reset form
|
|
================================================================
|
|
|
|
By submitting a suitably crafted email address making use of Unicode
|
|
characters, that compared equal to an existing user email when lower-cased for
|
|
comparison, an attacker could be sent a password reset token for the matched
|
|
account.
|
|
|
|
In order to avoid this vulnerability, password reset requests now compare the
|
|
submitted email using the stricter, recommended algorithm for case-insensitive
|
|
comparison of two identifiers from `Unicode Technical Report 36, section
|
|
2.11.2(B)(2)`__. Upon a match, the email containing the reset token will be
|
|
sent to the email address on record rather than the submitted address.

Bugfixes
|
|
========
|
|
|
|
* Fixed a regression in Django 3.0 by restoring the ability to use Django
|
|
inside Jupyter and other environments that force an async context, by adding
|
|
an option to disable :ref:`async-safety` mechanism with
|
|
:envvar:`DJANGO_ALLOW_ASYNC_UNSAFE` environment variable (:ticket:`31056`).
|
|
|
|
* Fixed a regression in Django 3.0 where ``RegexPattern``, used by
|
|
:func:`~django.urls.re_path`, returned positional arguments to be passed to
|
|
the view when all optional named groups were missing (:ticket:`31061`).
|
|
|
|
* Reallowed, following a regression in Django 3.0,
|
|
:class:`~django.db.models.expressions.Window` expressions to be used in
|
|
conditions outside of queryset filters, e.g. in
|
|
:class:`~django.db.models.expressions.When` conditions (:ticket:`31060`).
|
|
|
|
* Fixed a data loss possibility in
|
|
:class:`~django.contrib.postgres.forms.SplitArrayField`. When using with
|
|
``ArrayField(BooleanField())``, all values after the first ``True`` value
|
|
were marked as checked instead of preserving passed values (:ticket:`31073`).
