## Why mail_webhooks_update is rated Medium

This tool modifies webhook configuration, which controls how email systems receive event notifications. Misuse could redirect sensitive email notifications to attacker-controlled endpoints, intercept credentials, or disrupt email delivery workflows. This is reversible (Write, not Destructive), but the high impact on email security and potential for data exfiltration justifies 'high' severity.

From the tool's own definition: "mail_webhooks_update with description 'Update a webhook.' - the 'update' verb indicates modification of existing webhook configuration data."

## Use case

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