Summary

Duplicate Advisory: NodeVM nesting guard accepts array-shaped require and permits host RCE

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-8hr7-r645-pc6w. This link is maintained to preserve external references.

Original Description

vm2 is a sandbox for running untrusted Node.js code. In versions >= 3.11.4 and <= 3.11.6, the NodeVM constructor computes hasRealRequireConfig with typeof requireOpts === 'object' && requireOpts !== null, so an array-shaped require value (for example require: []) satisfies the guard that is meant to reject nesting without an explicit require configuration. makeResolverFromLegacyOptions() then destructures the array into undefined option fields and returns a resolver containing only NESTING_OVERRIDE.vm2. As a result, an attacker who can supply JavaScript executed by a NodeVM configured with truthy nesting and an array-shaped require (e.g. new NodeVM({nesting: true, require: []})) can require the host vm2 module, create an inner NodeVM with an attacker-chosen builtin allowlist (such as child_process), and execute arbitrary commands with the privileges of the host Node.js process, escaping the sandbox. Outer builtin restrictions do not constrain the attacker-created inner NodeVM. This issue is fixed in vm2 3.11.7.
