CVE-2026-42902

Estado: AnalizadaAlta (7.8)—

Improper authorization in Microsoft PowerToys allows an authorized 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.

Vector AV:L/PR:L/UI:N indica acceso local con permisos limitados sin interacción. CWE-285 (improper authorization) y descripción de escalada de privilegios confirma T1068. Impacto T1548 (abuse of elevation control mechanism) por el logro de privilegios elevados.

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.
