{"id":"DEBIAN-CVE-2026-97711","details":"Serialize JavaScript serializes JavaScript values to a superset of JSON that includes regular expressions and functions. From 7.1.1 until 7.1.2, function values serialized by serialize-javascript are not fully protected against script-closing tags in attacker-influenced function source because SCRIPT_CLOSE_REGEXP can consume a second closing tag inside one match. When the serialized function is embedded in a script element, the surviving closing tag terminates the element early and causes the remaining output to be parsed as HTML, enabling cross-site scripting in the page origin. Only function values are affected; ordinary data values and options.isJSON output are unaffected. This issue is fixed in version 7.1.2.","modified":"2026-10-01T10:00:10.322958468Z","published":"2026-09-29T16:17:19Z","upstream":["CVE-2026-97711"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-97711"}],"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-2026-97711.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-2026-97711.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"},{"fixed":"7.1.2+~5.0.4-1"}]}],"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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-97711.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"}]}
