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.","state":0,"publishedAt":"2026-09-29T16:00:33.534+00:00","modifiedAt":"2026-09-29T16:53:35.013+00:00","affected":[{"ecosystem":"Vendor product","name":"serialize-javascript","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"yahoo\",\n                    \"product\": \"serialize-javascript\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 7.1.1, < 7.1.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":2.3,"severity":"LOW"}],"references":["https://github.com/yahoo/serialize-javascript/security/advisories/GHSA-gfhx-hw2g-v5hg","https://github.com/yahoo/serialize-javascript/commit/2bdbaaff9cb8a4639135eb24cfcd383d3fefb534","https://github.com/yahoo/serialize-javascript/releases/tag/v7.1.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97711","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97711","identifiers":["CVE-2026-97711"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
