Estado: ModificadaMedia (6.7)—💥 PoC
In ion, there is a possible out of bounds read due to type confusion. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07560720; Issue ID: ALPS07559800.
CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 6.7
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.11%
Percentil entre todas las CVEs puntuadas: 1
Fecha de la puntuación: 12/10/2026
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.
