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,...
vm2 Library VM NodeVM Compromise
The vulnerability of the VM and NodeVM classes in the vm2 library of the NPM package manager is related to a flaw in the data protection mechanism during the processing of the allowAsync: false parameter. Exploiting this vulnerability allows an attacker to compromise the integrity and accessibili...
Protection Mechanism Failure
Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Protection Mechanism Failure through improper enforcement of the allowAsync option in the VM and NodeVM. An attacker can execute code asynchronously...

CVE-2026-92959
CVE-2026-92959 affects vm2 (a Node.js sandboxing library) versions prior to 3.11.8 . The vulnerability lies in the incomplete enforcement of the allowAsync: false option in VM and NodeVM. Although localPromise.prototype.then is patched to throw 'Async not available', the sandbox's Promise static ...
