CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
- Puntuación base: 5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 11%
- Percentil entre todas las CVEs puntuadas: 96
- Fecha de la puntuación: 9/10/2026
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.
