NVD Description

Note: Versions mentioned in the description apply only to the upstream n8n-oci-entrypoint package and not the n8n-oci-entrypoint package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

n8n versions before 2.34.1 contain a credential validation bypass in the MCP create_workflow_from_code tool when authentication type is set to an expression. Attackers with a valid MCP Bearer API key and knowledge of a target credential ID can persist unauthorized cross-project credential references on workflows in different projects.
