## Why create_update_set is rated Medium

The severity is medium because misuse could propagate unwanted configurations across ServiceNow instances, but update sets are designed to be manageable and revertible.

From the tool's own definition: "Tool name 'create_update_set' indicates creation of update sets in ServiceNow, which are reversible configurations used to manage changes across instances."
