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.
