GHSA-P6VX-979V-RG4C Seroval: `fromJSON()` Promise thenable assimilation invokes plugin-produced callables (bypass of GHSA-mv8w-475r-vwqw)

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 [email protected] GHSA-mv8w-475r-vwqw / CVE-2026-59940 and affects every plugin-capable release fr...
