CVE-2026-80097

Estado: AnalizadaAlta (8.6)—

Improper authentication in Microsoft Authenticator allows an unauthorized attacker to elevate privileges locally.

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:L con UI:R apunta a T1203 (ejecución en cliente). CWE-287 (autenticación defectuosa) permite suplantación de identidad (T1078) y escalada local (T1068). Microsoft Authenticator interactúa directamente con tokens de autenticación.

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.
