Short explanation

CVE-2026-110851 in n8n involves an authorization bypass in the Agents create endpoint. Authenticated users can supply an existing Agent ID to transfer Agent ownership to their own project and modify its configuration.

Why does it matter?

This vulnerability allows authenticated users to compromise cross-project data integrity and alter Agent ownership without proper authorization.

What should be done?

  • Follow vendor security advisories
  • Keep n8n installations up to date
  • Review access controls

Show the technical text from the sources

n8n before 2.41.4 and 2.42.x before 2.42.1 contains an authorization bypass in the Agents create endpoint, which accepts a caller-supplied Agent ID, checks permissions only against the requested project, and updates an existing Agent without verifying which project owns it. An authenticated user with read-only Agent access to another project can supply an existing Agent ID to move that Agent into their own project and rewrite its name, schema and version.
