RISK

Why caddy_add_matrix_federation_port is rated Medium

This tool creates or modifies Caddy web server configuration by adding a new site block for Matrix federation on port 8448. While reversible (can be undone via caddy_remove_site), it represents a Write action that modifies system configuration state. Severity is medium because misconfiguration could expose services or create security misalignment, but it doesn't irreversibly delete data or execute arbitrary code.
