NVD description
n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, an authenticated user with permission to create or modify workflows containing a Python Code Node could escape the sandbox and achieve arbitrary code execution on the task runner container. This issue only affects instances where the Python Task Runner is enabled. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.
What to do
- Upgrade n8n to
1.123.32or later (or the patched release of your branch: 2.17.4). - Do not expose the component's API or UI to the internet without authentication in front of it.
