CVE-2026-44009 Details
Description
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.2, This vulnerability is fixed in 3.11.2.
A sandbox breakout vulnerability allowing remote code execution has been identified in vm2 versions through 3.11.1. This issue arises in the 'handleException' method, where exceptions with a null prototype are incorrectly assumed to be proxied from the other side. Exploiting this flaw allows an attacker to access both the proxied and unproxied versions of a sandbox object, ultimately leading to execution of arbitrary commands on the host system.
Users should upgrade to vm2 version 3.11.2 or later.
