CWE-798 Use of Hard-coded Credentials in Yarbo Yarbo Android/IOS mobile application (CVE-2026-10557)
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.
AI Analysis
Technical Summary
CISA has identified security vulnerabilities in the Yarbo mobile application and cloud infrastructure, including issues with hard-coded credentials and missing authorization controls. These vulnerabilities affect versions prior to 3.17.4. The advisory references two CVEs: CVE-2026-10557 and CVE-2026-7368. No CVSS score or detailed technical exploit information is provided, and no known active exploitation has been reported. The vendor has not published explicit patch information, and the product is not a cloud service, so remediation responsibility lies with the user or vendor.
Potential Impact
The vulnerabilities could allow unauthorized access or misuse of the application or its cloud infrastructure due to hard-coded credentials and missing authorization checks. This may lead to unauthorized actions or data exposure within affected versions prior to 3.17.4. However, no active exploitation has been reported to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor official CISA and vendor communications for updates and apply any patches or updates once available. Until then, defensive measures as recommended by CISA should be implemented to minimize exploitation risk.
