SCA: security update for vm2 (GHSA-f8gf-w286-fmq2)
high Tenable Self-Hosted Container Security Plugin ID 473016
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- vm2 before 3.11.8 does not fully enforce the allowAsync: false option in VM and NodeVM. While
localPromise.prototype.then is replaced with a handler that throws 'Async not available', the sandbox's
Promise static methods (Promise.resolve, Promise.all, Promise.race, Promise.any, and Promise.allSettled)
still assimilate attacker-supplied thenables: native promise resolution performs PromiseResolveThenableJob
and invokes the sandboxed code's then method in a microtask without passing through the patched then, so
the async restriction is never applied. As a result, sandboxed script can schedule work that runs after
VM.run() or NodeVM.run() has returned and outside the configured timeout, continuing to execute after the
host believes execution is complete. (CVE-2026-92959)
Solution
Update the vm2 library and its related packages to version 3.11.8 or later.See Also
