CVE-2026-1442
Estado: AnalizadaAlta (7.8)—
Since the encryption algorithm used to protect firmware updates is itself encrypted using key material available to an attacker (or anyone paying attention), the firmware updates may be altered by an unauthorized user, and then trusted by a Unitree product, such as the Unitree Go2 and other models. This issue appears to affect all of Unitree’s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner’s knowledge.

"value": "Dado que el algoritmo de cifrado utilizado para proteger las actualizaciones de firmware está a su vez cifrado utilizando material clave disponible para un atacante (o cualquiera que preste atención), las actualizaciones de firmware pueden ser alteradas por un usuario no autorizado, y luego confiadas por un producto Unitree, como el Unitree Go2 y otros modelos. Este problema parece afectar a todas las ofertas actuales de Unitree a partir del 26 de febrero de 2026, y por lo tanto debe considerarse una vulnerabilidad tanto en los procesos de generación como de extracción de firmware. En el momento de esta publicación, no existe un mecanismo documentado públicamente para subvertir el proceso de actualización e insertar paquetes de firmware envenenados sin el conocimiento del propietario del equipo."
