CVE-2026-53985: Missing authentication for critical function vulnerability

Ground Station prior to 0.6.0 contains an unauthenticated denial-of-service vulnerability in the Socket.IO server's service_control event handler that allows any unauthenticated network peer to forcibly terminate the ground-station process by sending a single restart_service command. Attackers can connect to the Socket.IO server on port 7000 without credentials due to disabled authentication enforcement and a wildcard CORS policy, then emit the service_control event to terminate all active satellite-tracking sessions, SDR recording pipelines, demodulators, decoders, and rotator controllers, with repeated triggering possible in Docker deployments to create a persistent denial-of-service condition.
