That fix covered the promise and stream control nodes but not the async iterator node.\n\n### Impact\n\nAn application that passes untrusted input to `fromJSON` with plugins that return callable values can have those callables invoked during deserialization. What this allows depends on what the plugin's values do.\n\n### Affected versions\n\n- Versions up to 1.6.3 accept any value as the source.\n- 1.6.4 rejects the reported payload.\n- 1.6.5 to 1.6.7 check the source by node type, which a payload can get around by reusing a node id.\n- All versions up to 1.6.7 should be treated as affected.\n\n### Patches\n\nFixed in `seroval@1.6.8`. Streams and sequences are now internal class instances. The deserializer checks the source value with `instanceof`, so plain data and plugin values are rejected no matter which node id they use.\n\n### Workaroun","public_affected_ranges":["SEMVER: introduced 0; fixed 1.6.8"]}],"null_published_at":"2026-11-01T14:34:14.081Z","source_updated_at":"2026-10-28T21:17:15.000Z","source_disclosed_at":"2026-10-28T21:17:15.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"Source facts changed; compare the preserved prior revision.","null_first_observed_at":"2026-10-31T21:56:08.420Z"},{"id":"NVI-00009077","kind":"vulnerability","title":"Seroval: Deserialization invokes attacker-chosen callables: AsyncIteratorFactoryInstance calls source.on(listener) without type check","revision":1,"unknowns":["Customer inventory, deployment, reachability and exploitation have not been inspected."],"lifecycle":"active","identifiers":["GHSA-7rv5-mrxv-xcr9","CVE-2026-116580"],"plain_summary":"GitHub lists this reviewed advisory for seroval.
