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...

vm2: Host Promise rejection from an exposed constructor can terminate the vm2 host process

Summary An untrusted script run by VM.run can construct an embedder-exposed host function that returns a rejected native Promise and ignore the result. The sandbox-to-host construct trap forwards that Promise without applying the host-side rejection handling already used by the neighboring apply...

vm2: `allowAsync: false` can be bypassed through Promise thenable assimilation in VM and NodeVM

Summary When allowAsync is set to false, vm2 is expected to reject attempts to run asynchronous code. Direct use of Promise.prototype.then is blocked, but Promise static methods still assimilate attacker-controlled thenables. Promise.resolvethenable, Promise.allthenable, Promise.racethenable,...
