This tool modifies DNS records, which is a reversible write operation.

The severity is medium because misconfigured DNS could disrupt services, but the operation itself is reversible.

From the tool's own definition: "Tool name and description: 'unifi_update_dns_record' - 'Update an existing DNS record.' The verb 'Update' indicates modification of existing data."
