Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for n8n-io/n8n, n8n-io/n8n, n8n-io/n8n.
  2. 2Review the reported fix. Update n8n-io/n8n to 2.34.1; n8n-io/n8n to 2.33.4; n8n-io/n8n to 2.34.1; n8n-io/n8n to 2.33.4 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

n8n before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability in the @n8n/workflow-sdk node-schema loader used for MCP node-schema loading. The loader derives a node's schema module path directly from the attacker-supplied node type string without validating path-traversal sequences. An authenticated user with global:member privileges can reference malicious files via path traversal, causing code execution in the n8n main process.
