Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: CLI commands lacked RPC auth token support, allowing unauthenticated RPC access when auth was enabled.

Auth Bypass: IPC layer processed commands without mandatory authentication, enabling unauthorized control.

Privilege Escalation: Clients could trigger internal Serf functionality by using the internal query prefix, escalating privileges.
