CVE-2026-47305

Estado: AnalizadaAlta (7.8)—

Protection mechanism failure in Visual Studio allows an unauthorized attacker to execute code 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 + UI:R indica explotación del cliente (T1203): abrir archivo preparado en Visual Studio. El fallo de protección permite ejecución de código (T1059) y acceso a datos locales (T1005).

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.
