{"id":"CVE-2026-116581","published":"2026-10-26T21:18:15.903","lastModified":"2026-10-26T21:18:16.233","description":"Seroval facilitates JavaScript value stringification, including complex structures beyond JSON.stringify capabilities. 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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-835","CWE-1284"],"vendors":[],"products":[],"references":[{"url":"https://github.com/lxsmnsyc/seroval/commit/e176f9267e59ddd6c9de89cc9fe85c5b37a5b728","tags":[]},{"url":"https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8","tags":[]},{"url":"https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-97r2-qh9m-474h","tags":[]}],"exploitRefs":[{"url":"https://github.com/lxsmnsyc/seroval/commit/e176f9267e59ddd6c9de89cc9fe85c5b37a5b728","tags":[]},{"url":"https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8","tags":[]},{"url":"https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-97r2-qh9m-474h","tags":[]}],"hasPoc":true,"ai":null}
