Estado: Pendiente de análisisAlta (8.5)—

A role-based access control issue was identified in the administrative expression evaluation functionality. This could allow users with certain administrative roles to access expression testing capabilities beyond their intended permissions.

CVSS

Probabilidad de explotación (EPSS)

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:L indica acceso remoto con privilegios: T1210. CWE-863 (RBAC bypass) y acceso a funciones administrativas permite escalación y abuso de permisos (T1078, T1556).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
