CVSS

Versión: 3.0
Vector: CVSS:3.0/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 6.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 27%
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 7/10/2026

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
