CVE-2025-66518

Estado: AnalizadaAlta (8.8)—

Any client who can access to Apache Kyuubi Server via Kyuubi frontend protocols can bypass server-side config kyuubi.session.local.dir.allow.list and use local files which are not listed in the config.

This issue affects Apache Kyuubi: from 1.6.0 through 1.10.2.

Users are recommended to upgrade to version 1.10.3 or upper, which fixes the issue.

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.

UI:R y PR:L indican interacción del usuario con privilegios locales (T1203). La capacidad de acceder a archivos locales no permitidos (CWE-22, bypass de allowlist) permite lectura de datos sensibles (T1005) y potencial manipulación (T1565).

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.
