An access control vulnerability in the mobile app (APK v5.5.0) for Ghost Robotics' Vision 60 robot allows multiple simultaneous sessions to run without proper client validation or session integrity checks. An attacker with a modified version of the app can connect to the robot during an active, legitimate session. This allows the attacker to bypass control restrictions, intercept sensitive information (such as real-time video), and partially interact with the system unnoticed and without disconnecting the legitimate user, compromising confidentiality and operational security.
