CVE-2026-75851

Estado: AplazadaCrítica (9.4)—

ArcadeDB server (com.arcadedb:arcadedb-server) in versions 26.7.3 and earlier fails to propagate the authenticated principal to asynchronous command worker threads. When an HTTP command is submitted with awaitResponse:false, it executes on an async worker whose DatabaseContext has no bound user, causing the scripting authorization gate to become a no-op. A user with only read access to a single database can submit an asynchronous JavaScript (language=js) command via the /api/v1/command endpoint to run code with unrestricted host access (e.g., database.getSecurity().createUser) and create a server-wide administrator, escalating to full administrative control. Fixed in 26.8.1.

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.

Acceso de red con autenticación (PR:L) permite ejecución remota de JavaScript sin contexto de usuario, escalando a administrador del servidor. CWE-269 (autorización incorrecta) en endpoint /api/v1/command confirma explotación remota de servicio.

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.
