GHSA-53qw-q765-4fww Denial-of-service in Django

• PyPI Django: >= 2.2a1, < 2.2.26 → fixed in 2.2.26 • PyPI Django: >= 3.2a1, < 3.2.11 → fixed in 3.2.11 • PyPI Django: >= 4.0a1, < 4.0.1 → fixed in 4.0.1

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.
