Prior to 1.6.8, fromJSON rebuilds an AsyncIteratorFactoryInstance by calling source.on(listener) without requiring source to be a genuine internal stream. With untrusted Seroval input and an application plugin that returns a callable value or an object exposing an on method, a crafted node can reuse an identifier so the deserializer invokes the plugin-produced value. This is an incomplete-fix variant of CVE-2026-59940. The resulting confidentiality, integrity, or availability impact depends on the behavior exposed by the application plugin. This issue is fixed in version 1.6.8.","state":0,"publishedAt":"2026-10-26T21:18:15.523+00:00","modifiedAt":"2026-10-26T21:18:15.87+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3,"severity":"HIGH"}],"references":["https://github.com/lxsmnsyc/seroval/commit/3edc78b495ea0d6bd498143e5b3e56996607c5f2","https://github.com/lxsmnsyc/seroval/commit/50926b3ee198fb757e6ce3aa70efeed38d931c8d","https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8","https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-7rv5-mrxv-xcr9"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-116580","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-502"],"productCriteria":[],"sourceDates":{"published":"2026-10-26T21:18:15.523","lastModified":"2026-10-26T21:18:15.870"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
