**Name of the Vulnerable Software and Affected Versions** n8n versions 1.0.0 through less than 2.0.0 **Description** n8n is an open source workflow automation platform. A sandbox bypass vulnerability exists in the Python Code Node that uses Pyodide, affecting versions from 1.0.0 up to, but not including, 2.0.0. An authenticated user with permission to create or modify workflows can exploit this issue to execute arbitrary commands on the host system running n8n, with the same privileges as the n8n process. This vulnerability, tracked as CVE-2025-68668, has a CVSS score of 9.9 (Critical). Workarounds include disabling the Code Node by setting the environment variable `NODES EXCLUDE` to "["n8n-nodes-base.code"]", disabling Python support in the Code node by setting the environment variable `N8N PYTHON ENABLED` to false (available 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. The task runner-based Python implementation became the default starting with n8n version 2.0.0. **Recommendations** Upgrade to n8n version 2.0.0 or later. As a temporary workaround, disable the Code Node by setting the environment variable `NODES EXCLUDE` to "["n8n-nodes-base.code"]". As a temporary workaround, disable Python support in the Code node by setting the environment variable `N8N PYTHON ENABLED` to false. As a temporary workaround, configure n8n to use the task runner based Python sandbox via the `N8N RUNNERS ENABLED` and `N8N NATIVE PYTHON RUNNER` environment variables.
