Django 4.0.2 release notes
|
|
==========================
|
|
|
|
*February 1, 2022*
|
|
|
|
Django 4.0.2 fixes two security issues with severity "medium" and several bugs
|
|
in 4.0.1. Also, the latest string translations from Transifex are incorporated,
|
|
with a special mention for Bulgarian (fully translated).
|
|
|
|
CVE-2022-22818: Possible XSS via ``{% debug %}`` template tag
|
|
=============================================================
|
|
|
|
The ``{% debug %}`` template tag didn't properly encode the current context,
|
|
posing an XSS attack vector.
|
|
|
|
In order to avoid this vulnerability, ``{% debug %}`` no longer outputs an
|
|
information when the ``DEBUG`` setting is ``False``, and it ensures all context
|
|
variables are correctly escaped when the ``DEBUG`` setting is ``True``.
|
|
|
|
CVE-2022-23833: Denial-of-service possibility in file uploads
|
|
=============================================================
|
|
|
|
Passing certain inputs to multipart forms could result in an infinite loop when
|
|
parsing files.
|
|
|
|
