Why track_entity_changes is rated Low
This tool queries or retrieves change history for an entity—a read-only operation with no side effects. It detects and reports what changed, similar to viewing a changelog or audit log. No data is created, modified, deleted, or financial transaction executed. The low severity reflects minimal risk even if misused, as it only exposes historical information.
