NVD description
n8n is an open source workflow automation platform. Prior to versions 1.123.17 and 2.5.2, an authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n. This issue has been patched in versions 1.123.17 and 2.5.2.
What to do
- Upgrade n8n to
1.123.17or later (or the patched release of your branch: 2.5.2). - Do not expose the component's API or UI to the internet without authentication in front of it.
