CVE-2026-92951
validatedZero produced an exploit or a check.GHSA-6fvh-fgmg-3x7v ↗EUVD-2026-81600 ↗
description
vm2 before 3.11.7 can let sandboxed NodeVM code evade an external-package allowlist by requesting a similarly named package. This can cause unauthorized package code to run in the host process when the application uses a custom resolver and that resolver can find a colliding package in an attacker-influenced location.
mitigation
Upgrade the npm vm2 package to version 3.11.7 or later. Until upgraded, do not use custom resolvers that search attacker-writable package locations, and restrict such resolver paths to trusted dependencies.
fixed in 3.11.7
outcome
Mechanism verified: the exploit fired on the vulnerable build and stayed silent on the patched one, but the server it ran against was ours, so no check ships for it.
