  "details": "Ground Station prior to 0.6.0 contains an unauthenticated blind server-side request forgery vulnerability in the orbital-source configuration path that allows any unauthenticated Socket.IO client to cause the ground-station process to issue outbound HTTP requests to attacker-chosen destinations. Attackers can connect to the Socket.IO server on port 7000 without credentials due to disabled authentication enforcement and a wildcard CORS policy, then submit a data_submission event with submit-orbital-sources action to persist an attacker-supplied URL in the database, then trigger an orbital sync via the equally unauthenticated background_task:start event. The URL is stored with no scheme allowlist, no host validation, and no rejection of loopback, RFC1918, or link-local (cloud instance metadata at 169.254.169.254) addresses, and is passed directly to requests.get in _fetch_http_3le and _fetch_http_omm in backend/tlesync/source_adapters.py. HTTP status codes and error messages from the outbound request are emitted in the orbital_sync_state Socket.IO event to all connected clients, providing a serviceable oracle for interpreting internal-service and cloud-metadata responses even though the raw response body is not directly leaked. Because the malicious source persists in the database across restarts and re-fires every 24 hours on the scheduled sync cycle, the primitive gives durable long-term SSRF without the attacker needing to remain connected.",
