Why mikrotik_update_bridge is rated Medium
Updating bridge settings is a write operation that modifies network infrastructure configuration. While reversible (can be undone by further updates), it has high blast radius as misconfiguration could disrupt network connectivity for many users. Not destructive (no irreversible deletion), not execute (no arbitrary code execution), not financial.
