CVE-2026-10557 (GCVE-0-2026-10557)
Vulnerability from cvelistv5 – Published: 2026-06-12 14:05 – Updated: 2026-06-12 15:35

Title
Yarbo Android/iOS Mobile Application and Cloud Infrastructure Use of Hard-coded Credentials
Summary
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.
Severity ?

CVE-2026-7368 (GCVE-0-2026-7368)

Title
Yarbo Android/iOS Mobile Application and Cloud Infrastructure Missing Authorization
Summary
The Yarbo cloud does not enforce per-device or per-user authorization. Any client possessing valid credentials, whether the shared hard-coded credentials or legitimate per-user credentials, can subscribe to wildcard topics covering all robots globally, and can publish to any robot's command topic using only the robot's serial number (disclosed in the telemetry stream). Even after removal of hard-coded credentials from the app, a single compromised credential could still provide fleet-wide access without per-device access controls.
