Summary
Duplicate Advisory: vm2 sandbox escape on Node.js 26 through a stale PromiseThenLookupChain protector
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-27g9-p43v-cw3v. This link is maintained to preserve external references.

Original Description

vm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where Promise.prototype.finally() bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain protector in V8 14.6. Attackers can exploit this by creating an async function that returns a Promise with an attacker-controlled constructor Symbol.species, allowing them to reach the host Function constructor and process object for arbitrary code execution.
