Description Gianluca Gabrielli 2021-06-28 14:54:45 UTC
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.

This issue has High severity, according to the Django security policy [1].

Hi @Gianluca
based on the analysis from Keith, from SOC side there is nothing to be done, thus I'm assign it back to Security team.

Hi Gianluca,

I could not find info to confirm or deny that SOC is the maintainer of python-django in OBS. For the python-django versions that are used by SOC products there is no doubt, however for other versions I'm afraid SOC might not be the maintainer.
I'm still checking, but it might take time to get to a conclusive answer.

Cheers,
Christian
