Prior to 1.6.8, fromJSON and fromCrossJSON do not validate a sequence node's done index. A crafted done index can create an iterator that never finishes when application code consumes it to completion. An unauthenticated request to a service that deserializes untrusted input can therefore block the event loop, exhaust process memory, or make the service unavailable. This issue is fixed in version 1.6.8.","severity":"high","score":7.5,"published":"2026-10-26T20:41:52.905Z","modified":"2026-10-26T20:41:52.905Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-97r2-qh9m-474h","https://github.com/lxsmnsyc/seroval/commit/e176f9267e59ddd6c9de89cc9fe85c5b37a5b728","https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8"],"sources":[{"name":"CVE","id":"CVE-2026-116581","modified":"2026-10-26T20:41:52.905Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-116581"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T21:00:33.596Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
