CVE-2026-121687 · Severity: info · Published 2026-11-09

FrodoBots EarthRover Mini+ is a mobile robot with camera and sensors used in educational and consumer settings. The firmware exposes multiple local services—HTTP REST API, ADB, and SSH—without any authentication, allowing anyone connected to the device's WiFi to control the rover, access sensors, extract WiFi passwords, and gain root shell access.

## Quick answers

**Is CVE-2026-121687 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-121687 being exploited in the wild.

**How severe is CVE-2026-121687?** Informational severity, published 9 November 2026.

**Which products and versions are affected?** FrodoBots EarthRover Mini+ 6.2.4_6.2.5_0.614.0.

**Is there a fix for CVE-2026-121687?** No fixed version is recorded yet. The vendor advises that local interfaces require connection to the device's WiFi access point, which has a configurable password; securing the WiFi with a strong password limits access to authenticated network users. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.

**How is CVE-2026-121687 attacked?** It is attacked from the adjacent network, in device firmware.

**Am I affected by CVE-2026-121687?** Check whether you run FrodoBots EarthRover Mini+ at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix


The vendor advises that local interfaces require connection to the device's WiFi access point, which has a configurable password; securing the WiFi with a strong password limits access to authenticated network users.

## Technical details

CVE-2026-121687 covers three unauthenticated local interfaces in firmware version 6.2.4_6.2.5_0.614.0: HTTP REST API (port 80) with motor control and plaintext WiFi password disclosure, Android Debug Bridge (port 5555) providing root shell access, and SSH (port 22). Exploitation requires local network access (connection to the device's WiFi), but no authentication, allowing full device compromise and unauthorized sensor access.
