CVE-2026-26048

Estado: AplazadaAlta (7.5)—

The Wi-Fi router is vulnerable to de-authentication attacks due to the absence of management frame protection, allowing forged deauthentication and disassociation frames to be broadcast without authentication or encryption. An attacker can use this to cause unauthorized disruptions and create a denial-of-service condition.

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:N, UI:N indica red sin autenticación. El atacante es adversario en el medio (MITM) que forja tramas de gestión. El impacto es DoS por desautenticación de clientes.

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.
