Django security releases issued: 4.0.6 and 3.2.14
Posted by Mariusz Felisiak on July 4, 2022


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 
improvements 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.
