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":"2026-10-26T20:49:35.952+00:00","modifiedAt":"2026-10-27T14:18:01.418+00:00","affected":[{"ecosystem":"Vendor product","name":"seroval","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"lxsmnsyc\",\n                    \"product\": \"seroval\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.6.0, < 1.6.11\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"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":"MEDIUM"}],"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://www.cve.org/CVERecord?id=CVE-2026-116583","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116583","identifiers":["CVE-2026-116583"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
