What is CVE-2026-1285?

A vulnerability has been identified in multiple versions of the Django framework, which allows remote attackers to exploit the django.utils.text.Truncator.chars() and Truncator.words() methods, particularly when using the html=True configuration. This exploitation can potentially lead to a denial-of-service condition by providing crafted input filled with unmatched HTML end tags. It's important to note that previous unsupported versions of Django, such as 5.0.x, 4.1.x, and 3.2.x, may also be susceptible to similar threats.
