NVD description
n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could bypass the patch for CVE-2026-42232 in the XML node. When combined with other nodes, this could lead to RCE on the n8n host. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.
What to do
- Upgrade n8n to
1.123.43or later (or the patched release of your branch: 2.20.7, 2.22.1). - Do not expose the component's API or UI to the internet without authentication in front of it.
