CVE-2025-68668

Critical

Published: 26/12/2025(UTC)Translated: 05/08/2026(UTC)NVD NIST

Summary

n8n from version 1.0.0 to before 2.0.0 has a sandbox bypass vulnerability in the Python Code Node that uses Pyodide. An authenticated user with permission to create or modify workflows can exploit this to execute arbitrary commands on the host system running n8n, using the same privileges as the n8n process.

Risk Assessment

An attacker can execute arbitrary commands on the server, potentially leading to full compromise of the system and data.

Recommendation

Update n8n to version 2.0.0 or later, or if not possible, apply workarounds such as disabling the Code Node or Python support.

Original NVD description (English source)

n8n is an open source workflow automation platform. From version 1.0.0 to before 2.0.0, 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. This issue has been patched in version 2.0.0. Workarounds for this issue involve disabling the Code Node by setting the environment variable NODES_EXCLUDE: "[\"n8n-nodes-base.code\"]", disabling Python support in the Code node by setting the environment variable N8N_PYTHON_ENABLED=false, which was introduced in n8n version 1.104.0, and configuring n8n to use the task runner based Python sandbox via the N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER environment variables.
