The custom reviver passes the constructor name directly to new Function() without sanitization when recreating object prototypes, enabling attackers to inject arbitrary JavaScript through vectors such as postMessage in cross-frame communication contexts to achieve script execution within the application.","state":0,"publishedAt":"2026-05-20T20:16:41.063+00:00","modifiedAt":"2026-10-08T16:17:16.807+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/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","score":2.1,"severity":"LOW"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/Niccolo10/Security-Advisories/blob/main/CVE-2026-47099/cve-2026-47099.md","https://github.com/storybookjs/telejson/security/advisories/GHSA-ccgf-5rwj-j3hv","https://www.vulncheck.com/advisories/telejson-dom-based-xss-via-parse-function"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47099","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-05-20T20:16:41.063","lastModified":"2026-10-08T16:17:16.807"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
