Public CVEs
Published vulnerabilities in this vendor's products, from the NVD.
| CVE | Summary | Severity | Published |
|---|---|---|---|
| CVE-2026-7415 | The MQTT broker embedded in Yarbo firmware v2.3.9 is configured to allow anonymous connections with no topic-level read or write ACLs. Any host on the same network can subscribe to sensitive telemetry topics or publish control messages directly to the robot without authentication or authorization of any kind. | Critical 9.8 | 7 May 2026 |
| CVE-2026-7413 | A hidden, persistent backdoor was found in Yarbo firmware v2.3.9 that provides remote, unauthenticated (or weakly authenticated) access to privileged functionality. The backdoor is undocumented, cannot be disabled via user-facing settings, and survives factory reset and ordinary firmware updates. | High 7.2 | 7 May 2026 |
| CVE-2026-7414 | Yarbo firmware v2.3.9 contains hardcoded administrative credentials embedded in the firmware image. These credentials are identical across all devices running this firmware and cannot be changed or removed by end users, enabling trivial unauthorized access to device management interfaces by anyone who knows them. | Critical 9.8 | 7 May 2026 |
