CVE-2026-71289Network attack vectorHinoki check available

Unauthenticated agent command execution via exposed REST API

Published Aug 5, 2026 · Updated Aug 5, 2026

Missing authentication in NASA AMMOS ANMS allows remote attackers to issue commands to registered DTNMA agents through port 8089. The default Compose file exposes AMP Manager, while its CivetWeb setup disables domain checks and registers command and report routes without authentication. Network access to port 8089 is sufficient to enumerate agents, dispatch EXECSET commands, read reports, or clear stored reports without credentials.
