Estado: AnalizadaCrítica (9.8)—

The Aqara IAM/SSO Gateway (gw-builder.aqara.com) used a hardcoded OAuth client credential, which is an instance of "CWE-798: Use of Hard-coded Credentials." This issue has an estimated CVSS of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N (9.1 Critical). When combined with CVE-2026-50082, CVE-50084, and CVE-50085, 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.

Credencial OAuth hardcodeada en gateway expuesto a red sin autenticación (AV:N, PR:N, UI:N). Permite obtener acceso remoto a cuentas y configuración de SSO/IAM, facilitando takeover de dispositivos.

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.
