Hard-coded MQTT broker credentials in Yarbo Android and iOS applications allow remote unauthenticated attackers to subscribe to and publish on the cloud MQTT brokers serving the entire global Yarbo robot fleet. Because the credentials are identical across all users and devices and trivially extractable via APK decompilation, anyone knowing a target robot's serial number can read its telemetry or send arbitrary commands. No public exploit identified at time of analysis, but the CVSS 4.0 base score of 9.3 and CISA ICS advisory reflect the systemic, fleet-wide nature of the exposure.
Authorization bypass in Yarbo's cloud MQTT infrastructure allows any authenticated client to subscribe to wildcard topics covering the entire global robot fleet and to publish commands to any robot using only its serial number, which is itself disclosed in the telemetry stream. The flaw affects both the Yarbo Android/iOS mobile application and the backing cloud MQTT broker, and no public exploit identified at time of analysis, but the design defect means a single compromised credential yields fleet-wide control.
Anonymous MQTT access in Yarbo firmware v2.3.9 allows remote unauthenticated attackers on the local network to fully control the robotic lawn mower and exfiltrate sensitive telemetry data. The embedded MQTT broker accepts connections without credentials and enforces no topic-level access controls, enabling arbitrary publish/subscribe operations. No authentication, authorization, or message validation occurs. EPSS and KEV data not available; exploitation requires only network access to the robot's MQTT port (typically TCP 1883).
Hardcoded administrative credentials in Yarbo firmware v2.3.9 allow remote unauthenticated attackers to gain full device administrative access across all deployed units. The CVSS 9.8 critical score reflects the complete lack of authentication barriers (AV:N/AC:L/PR:N), with identical credentials embedded in every device that cannot be changed by end users. No active exploitation has been confirmed by CISA KEV, but a public GitHub repository reference suggests potential proof-of-concept availability. EPSS data unavailable, though the trivial exploitation path (no complexity, no privileges required) indicates high weaponization potential once credentials become widely known.
Undocumented persistent backdoor in Yarbo firmware v2.3.9 grants remote privileged access that survives factory reset and firmware updates. The backdoor requires high-privilege authentication (CVSS PR:H) but provides complete system control once accessed. No public exploit identified at time of analysis, though GitHub repository reference suggests technical disclosure exists. CVSS 7.2 reflects the high-privilege requirement, but persistence across resets and undocumented nature indicate significant supply chain or insider threat risk.
