{"id":"DEBIAN-CVE-2026-115754","details":"serialize-javascript from 7.0.1 before 7.1.3 contains a cross-site scripting vulnerability that allows attackers to break out of HTML script elements by ending serialized function source text with an unescaped \u003c/script. Attackers controlling a function's source via a spoofed toString() can combine surrounding output delimiters and later values to inject live markup such as img onerror handlers.","modified":"2026-10-24T14:00:06.641531819Z","published":"2026-10-23T14:17:52.590Z","upstream":["CVE-2026-115754"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-115754"}],"affected":[{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.0-2","6.0.0-2+deb12u1","6.0.1-1","6.0.2-1","7.0.4+~5.0.4-1","7.0.5+~5.0.4-1","7.0.7+~5.0.4-1","7.1.2+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115754.json"}},{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.2-1","7.0.4+~5.0.4-1","7.0.5+~5.0.4-1","7.0.7+~5.0.4-1","7.1.2+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115754.json"}},{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.2-1","7.0.4+~5.0.4-1","7.0.5+~5.0.4-1","7.0.7+~5.0.4-1","7.1.2+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115754.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
