CVE-2026-10557

CRITICAL

Yarbo Android/iOS Mobile Application and Cloud Infrastructure Use of Hard-coded Credentials

Title source: cna
STIX 2.1

Description

The Yarbo Android and iOS applications contain hard-coded MQTT broker credentials that are identical for all users and all devices. These credentials are embedded in the application binary and are readily extractable via APK decompilation. The credentials provide access to cloud MQTT brokers carrying real-time telemetry for the entire global Yarbo robot fleet. They allow both wildcard subscription to all robot telemetry topics and publishing to any robot's command topic using only the robot's serial number.
