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":"2026-10-26T20:35:49.975+00:00","modifiedAt":"2026-10-26T20:35:49.975+00:00","affected":[{"ecosystem":"Vendor product","name":"seroval","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"lxsmnsyc\",\n                    \"product\": \"seroval\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.6.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-7rv5-mrxv-xcr9","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116580","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116580","identifiers":["CVE-2026-116580"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
