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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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","score":5.3,"severity":null}],"references":["https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-f86p-h4j2-7qgj","https://github.com/lxsmnsyc/seroval/commit/1313ebbad9687bc0245e08bfd576376e57e0e5c1","https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.11"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-110462","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 26, 2026, 8:49:35 PM","dateUpdated":"Oct 27, 2026, 2:18:01 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
