Technical details
CVE-2026-121690 documents an absence of privilege separation in the EarthRover Mini+ firmware (version 6.2.4_6.2.5_0.614.0), where all processes execute as root. This is a design flaw rather than a code-level bug; an attacker who compromises any single service (e.g., via the unauthenticated HTTP API, MQTT command execution, or ADB access documented in related CVEs) gains immediate full device control. The vulnerability requires prior compromise of another service but has severe impact when combined with other flaws in the firmware.
