CVE-2023-43665:
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.

CVE-2023-46695:
An issue was discovered in Django 3.2 before 3.2.23, 4.1 before 4.1.13, and
4.2 before 4.2.7. The NFKC normalization is slow on Windows. As a consequence,
django.contrib.auth.forms.UsernameField is subject to a potential DoS (denial of
service) attack via certain inputs with a very large number of Unicode characters.
