Subject: Django: CVE-2022-34265: Potential SQL injection via Trunc(kind) and
 Extract(lookup_name) arguments.

In accordance with `our security release policy
<>`_, the 
Django team
is issuing
`Django 4.0.6 <>`_ and
`Django 3.2.14 <>`_.
These release addresses the security issue detailed below. We encourage all
users of Django to upgrade as soon as possible.

CVE-2022-34265: Potential SQL injection via ``Trunc(kind)`` and 
``Extract(lookup_name)`` arguments

``Trunc()`` and ``Extract()`` database functions were
subject to SQL injection if untrusted data was used as a
``kind``/``lookup_name`` value.

Applications that constrain the lookup name and kind choice to a known safe
list are unaffected.

This security release mitigates the issue, but we have identified 
to the Database API methods related to date extract and truncate that 
would be
beneficial to add to Django 4.1 before it's final release. This will 
impact 3rd
party database backends using Django 4.1 release candidate 1 or newer, 
until they
are able to update to the API changes. We apologize for the inconvenience.

Thanks Takuto Yoshikai (Aeye Security Lab) for the report.

This issue has severity "high" according to the Django security policy.
