CVE-2026-49186

Estado: AnalizadaAlta (8.6)—

The local MQTT broker does not enforce topic-level Access Control Lists (ACLs). This allows any client to subscribe using wildcard characters (# or +) to enumerate hidden network devices or publish rogue control commands.

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.

Acceso remoto a broker MQTT sin ACLs (CWE-287) requiere privilegios (PR:H) en red; permite enumerar dispositivos (T1078) y publicar comandos maliciosos (manipulación T1565).

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.
