How to fix?

Upgrade Alpine:3.24 py3-django to version 4.2.28-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-django package and not the py3-django package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

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.
