ArcadeDB before 26.7.3 Privilege Escalation via JavaScript Trigger

Assigner: VulnCheck
Reserved: 29.07.2026 Published: 02.08.2026 Updated: 02.08.2026

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.
