CVE-2026-49198

Estado: AnalizadaAlta (8.3)—

Improper access control in the MQTT broker allows wildcard topic subscriptions, exposing all MQTT traffic to unauthorized actors.

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.

AV:N/PR:L: acceso remoto con privilegios locales requeridos es T1210. Impacto: lectura de tráfico MQTT (T1005); posible intercepción de datos en tránsito (T1557).

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.
