{"id":"DEBIAN-CVE-2025-32873","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().","modified":"2026-09-01T20:05:46.038305457Z","published":"2025-05-08T04:17:18.157Z","upstream":["CVE-2025-32873"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-32873"}],"affected":[{"package":{"name":"python-django","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-django?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3:3.2.25-0+deb12u1"}]}],"versions":["3:3.2.19-1","3:3.2.19-1+deb12u1","3:3.2.19-1+deb12u1~bpo11+1","3:3.2.19-1+deb12u2","3:3.2.20-1","3:3.2.20-1.1","3:3.2.21-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32873.json"}},{"package":{"name":"python-django","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-django?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3:4.2.21-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32873.json"}},{"package":{"name":"python-django","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-django?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3:4.2.21-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32873.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
