Auth bypass in Efstratios Goudelis Ground Station
CVE-2026-53984
Ground Station prior to 0.6.0 contains an unauthenticated database-destruction and arbitrary-data-injection vulnerability in the Socket.IO server's database_backup event handler that allows any unauthenticated network peer to wipe or replace the entire SQLite database by sending a single full_restore command with a caller-supplied SQL blob. 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 database_backup event to drop every existing table and recreate the database from attacker-controlled CREATE TABLE and INSERT INTO statements executed via raw exec_driver_sql, permanently destroying all satellite records, orbital sources, hardware configurations, and observation schedules, or planting fabricated orbital-source URLs and observation entries that redirect the ground station to attacker-controlled servers on the next scheduled sync.
