How to fix?

Upgrade Debian:12 python-django to version 2:3.2.11-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-django package and not the python-django package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1. UserAttributeSimilarityValidator incurred significant overhead in evaluating a submitted password that was artificially large in relation to the comparison values. In a situation where access to user registration was unrestricted, this provided a potential vector for a denial-of-service attack.
