Description
A fulfilled Promise node deserialized by `fromJSON()` can trigger unintended invocation of a plugin-produced callable through native ECMAScript thenable assimilation. This bypasses the type-confusion fix in `seroval@1.5.3` (GHSA-mv8w-475r-vwqw / CVE-2026-59940) and affects every plugin-capable release from `0.12.0` through the current `1.6.0`.
