Doc Text:	A flaw was found in vm2. An attacker can achieve arbitrary code execution on the host system by escaping sandbox isolation through the command-line interface (CLI) tool. By supplying a malicious script that uses the require() function to re-execute itself within the host environment, untrusted code can bypass security boundaries to access host modules and files.

Description OSIDB Bzimport 2026-09-17 14:09:21 UTC

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses require(__filename) to re-execute itself in the host realm, bypassing sandbox isolation and accessing host modules like fs and child_process.
