## Why update_visitor is rated Medium

This tool modifies visitor account records reversibly. It is a Write operation because it changes data that can be undone or modified again. Severity is medium due to potential for misconfiguration or unauthorized access grants affecting network guest access policies, though the blast radius is limited to visitor accounts rather than critical infrastructure or financial systems.

From the tool's own definition: "Tool name is 'update_visitor' and description states 'Update an existing visitor account', indicating modification of existing data."

## Use case

AI agents use update_visitor to create or update resources in API-Central, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API-Central environment.
