CVE-2023-43665 is fixed in 3 products on 1 platform, first by python-django 1:1.11.11-1ubuntu1.21+esm2, released October 4, 2023. It is not reported as exploited. Patch Radar priority: High.
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.
