## Overview

n8n before 2.41.4 and 2.42.0 before 2.42.1 does not validate credential ids stored in agent node parameters when an editor saves a shared workflow, because the check inspects only a node's credentials field. An editor can configure a Message an Agent node in inline mode with tools they control to resolve the owner's credentials and send decrypted secrets to an attacker-chosen destination.
