CVE-2024-3656

Estado: AplazadaAlta (8.1)—💥 Exploit

A flaw was found in Keycloak. Certain endpoints in Keycloak's admin REST API allow low-privilege users to access administrative functionalities. This flaw allows users to perform actions reserved for administrators, potentially leading to data breaches or system compromise.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Puntuación base: 8.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 2.86%
Percentil entre todas las CVEs puntuadas: 86
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.
