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 is an open source workflow automation platform. Prior to 2.27.4 and 2.28.1, the AI Agents feature did not enforce the Allowed HTTP Request Domains restriction configured on credentials when an MCP tool was pointed at an arbitrary URL, allowing a member-level user with use-only access to a shared credential to send its secret to an external server they control. This issue is fixed in versions 2.27.4 and 2.28.1.
