CVE-2025-32873: Djangoproject Django

Medium severity, CVSS 5.3. EPSS: 14.2% chance of exploitation in the next 30 days.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

Affected products

• Djangoproject Django: from 4.2.0, before 4.2.21 (fixed in 4.2.21); from 5.1, before 5.1.9 (fixed in 5.1.9); version 5.2 only
