{"id":"DEBIAN-CVE-2024-34078","details":"html-sanitizer is an allowlist-based HTML cleaner. If using `keep_typographic_whitespace=False` (which is the default), the sanitizer normalizes unicode to the NFKC form at the end. Some unicode characters normalize to chevrons; this allows specially crafted HTML to escape sanitization. The problem has been fixed in 2.4.2.","modified":"2026-08-27T23:05:04.482352495Z","published":"2024-05-06T15:15:24.187Z","upstream":["CVE-2024-34078"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-34078"}],"affected":[{"package":{"name":"python-html-sanitizer","ecosystem":"Debian:11","purl":"pkg:deb/debian/python-html-sanitizer?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.1-2+deb11u1"}]}],"versions":["1.9.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-34078.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
