Estado: ModificadaAlta (8.8)—💥 Exploit
Vulnerabilidad uso después de la liberación (use-after-free) en Apple Safari anterior v4.0.5 permite a atacantes remotos ejecutar código de su elección o causar una denegación de servicio (caída de aplicación) a través de un documento HTML con etiquetas inadecuadamente anidadas.
CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 8.8
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 12%
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.
