## Why mittwald_backup_schedule_update is rated Medium

This tool modifies existing backup schedule data reversibly (Write category), not destructively. However, severity is high because misuse could disable or alter backup protection for production systems, creating significant data loss risk if the backup schedule is misconfigured and actual backups fail. The OAuth-based execution model means the tool acts with user credentials and could affect critical infrastructure.

From the tool's own definition: "Tool performs 'Update a backup schedule' which modifies backup configuration settings via CLI command execution."
