{"id":"PYSEC-2025-37","details":"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().","aliases":["BIT-django-2025-32873","CVE-2025-32873","GHSA-8j24-cjrq-gr2m"],"modified":"2025-06-18T15:41:59.060544Z","published":"2025-05-08T04:17:18Z","references":[{"type":"ARTICLE","url":"https://www.djangoproject.com/weblog/2025/may/07/security-releases/"},{"type":"WEB","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"WEB","url":"https://groups.google.com/g/django-announce"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/05/07/1"}],"affected":[{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2"},{"fixed":"4.2.21"},{"introduced":"5.1"},{"fixed":"5.1.9"},{"introduced":"5.2"},{"fixed":"5.2.1"}]}],"versions":["4.2","4.2.1","4.2.10","4.2.11","4.2.12","4.2.13","4.2.14","4.2.15","4.2.16","4.2.17","4.2.18","4.2.19","4.2.2","4.2.20","4.2.3","4.2.4","4.2.5","4.2.6","4.2.7","4.2.8","4.2.9","5.1","5.1.1","5.1.2","5.1.3","5.1.4","5.1.5","5.1.6","5.1.7","5.1.8","5.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/django/PYSEC-2025-37.yaml"}}],"schema_version":"1.7.3"}
