Technical details
Ground Station versions before 0.6.0 contain an unauthenticated server-side request forgery (SSRF) vulnerability in the orbital-source configuration handling. The root cause is that Socket.IO authentication is disabled and the application accepts unauthenticated data_submission events with submit-orbital-sources actions that store arbitrary URLs in the database without validation (no scheme allowlist, host validation, or rejection of loopback/RFC1918/link-local addresses). An unauthenticated network attacker can persist a malicious URL in the database by connecting to port 7000, then trigger orbital sync via background_task:start to cause the backend to issue requests.get() calls to attacker-chosen destinations in backend/tlesync/source_adapters.py (_fetch_http_3le and _fetch_http_omm). HTTP status codes and error messages are leaked via orbital_sync_state Socket.IO events to all clients, providing an oracle for interpreting responses from internal services and cloud metadata endpoints (e.g., 169.254.169.254). Because the malicious source persists across restarts and re-fires every 24 hours, the attacker achieves durable SSRF without maintaining a connection. The vulnerability is fixed in version 0.6.0 or later.
