GHSA-4rrr-2h4v-f3j9 Django has Inefficient Algorithmic Complexity

• PyPI Django: >= 6.0a1, < 6.0.2 → fixed in 6.0.2 • PyPI Django: >= 5.2a1, < 5.2.11 → fixed in 5.2.11 • PyPI Django: >= 4.2a1, < 4.2.28 → fixed in 4.2.28

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. `django.utils.text.Truncator.chars()` and `Truncator.words()` methods (with `html=True`) and the `truncatechars_html` and `truncatewords_html` template filters allow a remote attacker to cause a potential denial-of-service via crafted inputs containing a large number of unmatched HTML end tags. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Seokchan Yoon for reporting this issue.
