CVSS 3.1 Score 7.5 of 10 (high)
Details
Summary
CVE-2023-43665 is a denial-of-service vulnerability affecting Django versions 3.2 before 3.2.22, 4.1 before 4.1.12, and 4.2 before 4.2.6. The issue lies in the django.utils.text.Truncator chars() and words() methods, which are used to implement the truncatechars_html and truncatewords_html template filters. If these methods are used with html=True and receive certain inputs containing very long, potentially malformed HTML text, they may become unresponsive, leading to a denial-of-service condition. This vulnerability is a result of an incomplete fix for the previously reported CVE-2019-14232.
