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...

GHSA-F8GF-W286-FMQ2 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,...

CVE-2026-104846 Seroval: `fromJSON()` Promise thenable assimilation invokes plugin-produced callables (bypass of CVE-2026-59940)

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. From 0.12.0 until 1.6.2, fromJSON deserialization of a fulfilled Promise control node can pass a plugin-produced callable-bearing thenable to a native Promise resolver. ECMAScript thenab...
