Descrição
n8n is a workflow automation platform. In versions prior to 1.123.69, 2.33.4, and 2.34.1, the JavaScript Code node-s VM sandbox did not freeze the sandbox-s Function.prototype, allowing an authenticated user with the ability to create and execute workflows to pollute it from within a Code node execution and recover a reference to the host-s globalThis, resulting in a sandbox escape. The full exploit chain additionally depends on specific modules being available as allowlisted imports in the deployment-s configuration. The issue is fixed in versions 1.123.69, 2.33.4, and 2.34.1.
