# Django 3.2.5 release notes

July 1, 2021

Django 3.2.5 fixes a security issue with severity „high” and several bugs in 3.2.4. Also, the latest string translations from Transifex are incorporated.

## 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.
