CVE-2026-92950 Details
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.
A sandbox escape vulnerability has been identified in vm2 versions prior to 3.11.7. This vulnerability exists in the command-line interface (CLI) tool, where attackers can execute arbitrary code in the host Node.js process. The issue arises because the CLI runs scripts with `require` access to host modules, such as `fs` and `child_process`, without proper isolation. By supplying a malicious script that uses `require(__filename)`, an attacker can bypass the sandbox and execute code on the host system.
Users are advised to update vm2 to version 3.11.7 or later, where this vulnerability has been patched.
