CVE-2026-67356

ArcadeDB before 26.7.3 binds the real LocalDatabase object into JavaScript trigger contexts with HostAccess.ALL, allowing schema-admins to call getSecurity().createUser() without permission checks. Attackers with UPDATE_SCHEMA permission can create triggers that execute JavaScript to create server-wide admin users, escalating privileges beyond their authorization level.

Summary		(es) ArcadeDB antes de 26.7.3 enlaza el objeto LocalDatabase real en contextos de disparadores de JavaScript con HostAccess.ALL, permitiendo a los administradores de esquema llamar a getSecurity().createUser() sin comprobaciones de permisos. Atacantes con permiso UPDATE_SCHEMA pueden crear disparadores que ejecuten JavaScript para crear usuarios administradores a nivel de servidor, escalando privilegios más allá de su nivel de autorización.
