## Why unifi_unblock_client is rated Medium

This tool reverses a block state on a network client/device, which is a reversible write/modify operation (toggling access control state). It does not delete data, execute arbitrary code, or involve financial transactions. Misuse could allow unauthorized devices back onto the network, hence medium severity.

From the tool's own definition: "Unblock a previously blocked client/device by MAC address"
