CVE-2023-43665

7.5 highEPSS 1.5%

High (7.5). EPSS 1.5% chance of exploitation in the next 30 days. Fixed in django 3.2.22, 4.1.12, 4.2.6.

In Django 3.2 before 3.2.22, 4.1 before 4.1.12, and 4.2 before 4.2.6, the django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.
