CVE-2026-22709CVE-2026-22709

Description

vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, `Promise.prototype.then` `Promise.prototype.catch` callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code. In lib/setup-sandbox.js, the callback function of `localPromise.prototype.then` is sanitized, but `globalPromise.prototype.then` is not sanitized. The return value of async functions is `globalPromise` object. Version 3.10.2 fixes the issue.
