CVE-2026-44007 · vm2: nesting: true bypasses require: false, allowing sandbox escape to arbitrary OS command execution

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.1, when a NodeVM is created with nesting: true, sandbox code can unconditionally require('vm2') regardless of the outer VM's require configuration — including require: false. With access to vm2, the sandbox constructs a new inner NodeVM with its own unrestricted require settings and executes arbitrary OS commands on the host. Any application that runs untrusted code inside a NodeVM with nesting: true is fully compromised. This vulnerability is fixed in 3.11.1.
