GHSA-8j24-cjrq-gr2m Django has a denial-of-service possibility in strip_tags()

• PyPI Django: >= 4.2, < 4.2.21 → fixed in 4.2.21 • PyPI Django: >= 5.1, < 5.1.9 → fixed in 5.1.9 • PyPI Django: >= 5.2, < 5.2.1 → fixed in 5.2.1

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().
