Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-jxxv-8r27-vm4p. This link is maintained to preserve external references.

Original Description

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.
