CVE-2026-7415
CriticalSummary
The MQTT broker in Yarbo firmware version 2.3.9 is configured to allow anonymous connections with no topic-level access control. Any host on the same network can subscribe to sensitive telemetry topics or publish control messages without any authentication.
Risk Assessment
The lack of authentication allows unauthorized users to access sensitive data and manipulate the robot, posing a significant security threat to the system.
Recommendation
It is recommended to configure MQTT brokers to enforce authentication and implement topic-level access control to mitigate the risk of unauthorized access.
Original NVD description (English source)
The MQTT broker embedded in Yarbo firmware v2.3.9 is configured to allow anonymous connections with no topic-level read or write ACLs.
