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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-97711)\n\nAffected packages:\n\n- `serialize-javascript >= 7.1.1, < 7.1.2`\n\nPatched in:\n\n- `serialize-javascript 7.1.2`\n\nSource: https://github.com/advisories/GHSA-gfhx-hw2g-v5hg\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-30 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-97711.json)","depth":"sunlit","depthScore":13,"depthScoreParts":{"impact":12.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
