Probabilidad de explotación en los próximos 30 días: 0.11%
Percentil entre todas las CVEs puntuadas: 1
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1195.002 Compromise Software Supply Chaininitial access80 %
Impacto secundarioT1059 Command and Scripting Interpreterexecution75 %

AV:L + UI:P + interacción del usuario (reemplazo de instalador) → T1203. El atacante local reemplaza el instalador (T1195.002: cadena de suministro, componente de software) para ejecutar código malicioso al instalar (T1059).

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.
