Summary

n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node

Details

Impact

A sandbox bypass vulnerability exists in the Python Code Node that uses Pyodide.

An authenticated user with permission to create or modify workflows can exploit this vulnerability to execute arbitrary commands on the host system running n8n, using the same privileges as the n8n process.

Patches

In n8n version 1.111.0, a task-runner-based native Python implementation was introduced as an optional feature, providing a more secure isolation model.

To enable it, you need to configure the N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER environment variables.

This implementation became the default starting with n8n version 2.0.0.

Workarounds

Disable the Code Node by setting the environment variable NODES_EXCLUDE: "[\"n8n-nodes-base.code\"]" (Docs)
Disable Python support in the Code node by setting the environment variable N8N_PYTHON_ENABLED=false, which was introduced in n8n version 1.104.0.
Configure n8n to use the task runner based Python sandbox via the N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER environment variables. (Docs)
