UTMStack before 11.2.16 contains a missing authorization vulnerability in UTMIncidentCommandWebsocket.processCommand(), the handler mapped to the /command/{hostname} STOMP destination, where no role check or command allowlist is applied before forwarding supplied commands. Any authenticated user, regardless of role, can send arbitrary operating-system commands over gRPC to any connected agent, resulting in command execution on monitored endpoints where agent processes commonly run as root or SYSTEM.
