CVE-2026-121689 · Severity: info · Published 2026-11-09

The FrodoBots EarthRover Mini+ robot stores Wi-Fi passwords in plaintext and exposes them through unauthenticated APIs and diagnostic exports. An attacker with network access to the device's Wi-Fi could extract these credentials, gain access to the local network, and potentially use the robot to pivot into a user's home or office network.

## Technical details

CVE-2026-121689 is a credential exposure vulnerability in the EarthRover Mini+ firmware affecting version 6.2.4_6.2.5_0.614.0. The Wi-Fi pre-shared key (PSK) is stored in plaintext in wpa_supplicant.conf and can be retrieved via unauthenticated HTTP REST API endpoints, diagnostic export services, or unauthenticated ADB root shell access on port 5555. An attacker with local network access or physical proximity to the device can extract the Wi-Fi password without authentication, enabling lateral movement onto the user's network.
