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.","epss":{"date":"2026-11-02","percentile":0.27703,"score":0.00342},"exploits":[],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"}],"modifiedAt":1793643109130,"publishedAt":1793046949975,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-7rv5-mrxv-xcr9"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/lxsmnsyc/seroval/commit/3edc78b495ea0d6bd498143e5b3e56996607c5f2"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/lxsmnsyc/seroval/commit/50926b3ee198fb757e6ce3aa70efeed38d931c8d"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8"},{"source":"OSV / GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/advisories/GHSA-7rv5-mrxv-xcr9"},{"source":"OSV / GitHub Security Advisories","tags":["osv"],"url":"https://osv.dev/vulnerability/GHSA-7rv5-mrxv-xcr9"}],"remediation":[{"kind":"fix","source":"OSV GHSA-7rv5-mrxv-xcr9","text":"seroval (npm): OSV reports a fixed version 1.6.8.
