CVSS
- Versión: 2.0
- Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
- Puntuación base: 4.6
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.71%
- Percentil entre todas las CVEs puntuadas: 86
- 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.
