From 1.6.0 until 1.6.11, the JavaScript-output APIs derive a typed array's constructor name from a property on the value that can be replaced by an own constructor property. When application code copies untrusted properties onto a typed array and then passes it to serialize, serializeAsync, crossSerialize, crossSerializeAsync, crossSerializeStream, Serializer, or compileJSON, the attacker-controlled name is written as executable JavaScript and can run in the page receiving the output. This issue is fixed in version 1.6.11.","state":0,"publishedAt":"2026-10-26T21:18:16.653+00:00","modifiedAt":"2026-10-27T15:16:40+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/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":5.3,"severity":"MEDIUM"}],"references":["https://github.com/lxsmnsyc/seroval/commit/1313ebbad9687bc0245e08bfd576376e57e0e5c1","https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.11","https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-f86p-h4j2-7qgj"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-116583","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-79","CWE-94"],"productCriteria":[],"sourceDates":{"published":"2026-10-26T21:18:16.653","lastModified":"2026-10-27T15:16:40.000"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
