Impact An authenticated user with permission to create or modify workflows could bypass the patch for GHSA-hqr4-h3xv-9m3r in the XML node. When combined with other nodes, this could lead to RCE on the n8n host. Patches The issue has been fixed in n8n versions 1.123.43, 2.20.7, and 2.22.1. Users should upgrade to one of these versions or later to remediate the vulnerability. Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Limit workflow creation and editing permissions to fully trusted users only. - Disable the XML node by adding "n8n-nodes-base.xml" to the "NODES_EXCLUDE" environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures. *** n8n has adopted CVSS 4.0 as primary score for all security advisories.
