CVE-2026-64859

Estado: AplazadaCrítica (9.1)—

New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.7, the admin user list and user lookup APIs, including GET /api/user/, return User.AccessToken as access_token because User model objects are serialized after queries use Omit("password"), allowing an authenticated administrator to obtain the root user's bearer token and access root-only system configuration APIs. This issue is fixed in version 1.0.0-rc.7.

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.

Explotación de servicio remoto (API REST) por administrador autenticado (PR:H) sin interacción. Impactos: lectura de tokens de acceso (T1005), escalada a credenciales root (T1078.001) y manipulación de cuentas administrativas (T1098.003).

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.
