CVE-2026-50085

Estado: AnalizadaCrítica (9.8)—

The Aqara Board service (op-test.aqara.com) accepts arbitrary MQTT command payloads, and forwards them to the platfom's HiveMQ broker without authentication. This is an instance of "CWE-306: Missing Authentication for Critical Function" and has an estimated CVSS ofCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L (8.6 High). When combined with CVE-2026-50082, CVE-50083, and CVE-50084, this can lead to a fully unauthenticated, remote takeover of affected devices.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de aplicación expuesta sin autenticación (AV:N/PR:N) permite enviar comandos MQTT arbitrarios; el acceso a función crítica sin autenticación (CWE-306) y confidencialidad/integridad alta (C:H/I:H) indican compromiso de credenciales/cuentas y ejecución remota.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
