CVE-2026-10557

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

Published Jun 12, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Solution

Yarbo recommends users update the Yarbo mobile app to 3.17.4 or later. Server-side broker authorization will be enforced automatically upon deployment of the May 2026 update. No user action is required.
