NVD description
n8n is an open source workflow automation platform. Prior to 1.123.48, 2.21.8, and 2.22.4, 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 vulnerability is fixed in 1.123.48, 2.21.8, and 2.22.4.
What to do
- Upgrade n8n to
1.123.48or later (or the patched release of your branch: 2.21.8, 2.22.4). - Do not expose the component's API or UI to the internet without authentication in front of it.
