Prior to 7.1.3, the function-source escaping logic does not neutralize a bare closing-script prefix when attacker-influenced function source text ends exactly at that prefix. Because each function body is escaped independently, a delimiter supplied by surrounding serialized output can terminate an HTML script element, and a later serialized value supplies injected markup that becomes a live element in the page. Exploitation requires control of a serialized function's source text, such as through a spoofed toString(). This issue is fixed in version 7.1.3.","state":0,"publishedAt":"2026-10-23T22:16:59.153+00:00","modifiedAt":"2026-10-23T22:16:59.153+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:L/VI:L/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","score":2.1,"severity":"LOW"}],"references":["https://github.com/yahoo/serialize-javascript/commit/2864b3c6260a3bfd52d2db3e70d1a079de108a61","https://github.com/yahoo/serialize-javascript/pull/235","https://github.com/yahoo/serialize-javascript/releases/tag/v7.1.3","https://github.com/yahoo/serialize-javascript/security/advisories/GHSA-m5mm-p8h7-m29v"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-115897","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Received","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-10-23T22:16:59.153","lastModified":"2026-10-23T22:16:59.153"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
