Django security releases issued: 3.2.5 and 3.1.13
In accordance with our security release policy, the Django team is issuing Django 3.2.5 and Django 3.1.13. These releases address the security issue with severity "high" detailed below. We encourage all users of Django to upgrade as soon as possible.
CVE-2021-35042: Potential SQL injection via unsanitized QuerySet.order_by() input
Unsanitized user input passed to QuerySet.order_by() could bypass intended column reference validation in path marked for deprecation resulting in a potential SQL injection even if a deprecation warning is emitted.
As a mitigation the strict column reference validation was restored for the duration of the deprecation period. This regression appeared in 3.1 as a side effect of fixing #31426.
The issue is not present in the main branch as the deprecated path has been removed.
Thanks to Joel Saunders for the report.
