{"id":"DEBIAN-CVE-2026-116802","details":"DOMPurify before 3.4.17 contains a cross-site scripting vulnerability that allows attackers to bypass the SMIL attributeName=href guard when PARSER_MEDIA_TYPE is application/xhtml+xml, because transformCaseFunc does not lowercase attribute names. Attackers can submit SVG with an animate or set element using attributeName=\"href\" and a javascript: entry in values to execute script when users click the sanitized link.","modified":"2026-10-27T20:00:07.757767110Z","published":"2026-10-27T00:17:11.637Z","upstream":["CVE-2026-116802"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-116802"}],"affected":[{"package":{"name":"node-dompurify","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-dompurify?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1+dfsg+~2.4.0-1","2.4.1+dfsg+~2.4.0-2","2.4.1+dfsg+~2.4.0-2+deb12u1","3.0.9+dfsg+~3.0.5-1","3.1.6+dfsg+~3.0.5-1","3.1.7+dfsg+~3.0.5-1","3.1.7+dfsg+~3.0.5-2","3.2.5+dfsg-1","3.3.2+dfsg-1","3.3.3+dfsg-1","3.3.3+dfsg-2","3.4.1+dfsg-1","3.4.12+dfsg-1","3.4.13+dfsg-1","3.4.13+dfsg-2","3.4.16+dfsg-1","3.4.2+dfsg-1","3.4.5+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116802.json"}},{"package":{"name":"node-dompurify","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-dompurify?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.7+dfsg+~3.0.5-2","3.2.5+dfsg-1","3.3.2+dfsg-1","3.3.3+dfsg-1","3.3.3+dfsg-2","3.4.1+dfsg-1","3.4.12+dfsg-1","3.4.13+dfsg-1","3.4.13+dfsg-2","3.4.16+dfsg-1","3.4.2+dfsg-1","3.4.5+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116802.json"}},{"package":{"name":"node-dompurify","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-dompurify?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.7+dfsg+~3.0.5-2","3.2.5+dfsg-1","3.3.2+dfsg-1","3.3.3+dfsg-1","3.3.3+dfsg-2","3.4.1+dfsg-1","3.4.12+dfsg-1","3.4.13+dfsg-1","3.4.13+dfsg-2","3.4.16+dfsg-1","3.4.2+dfsg-1","3.4.5+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116802.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
