Description
A denial of service (DoS) vulnerability exists in Django versions prior to 3.2.22, 4.1.12, and 4.2.6 in the django.utils.text.Truncator chars() and words() methods when used with html=true. This affects the truncatechars_html and truncatewords_html template filters. The issue arises from an incomplete fix for a previous vulnerability (CVE-2019-14232).
