Privilege Escalation via JavaScript Triggers in ArcadeDB

Publication date: 2026-08-02

Last updated on: 2026-08-02

Assigner: VulnCheck

Description
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.

Executive Summary

ArcadeDB versions before 26.7.3 have a vulnerability where JavaScript triggers can access the real LocalDatabase object with full permissions. This allows attackers with UPDATE_SCHEMA permission to create malicious triggers that execute JavaScript code to create admin users without proper permission checks.

If exploited, this vulnerability allows attackers to escalate their privileges to server-wide admin level, bypassing normal authorization. This could lead to unauthorized access, data manipulation, or complete system compromise.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating compliance requirements for GDPR (data protection) and HIPAA (health information security). Organizations may face legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Upgrade ArcadeDB to version 26.7.3 or later to address the HostAccess.ALL vulnerability in JavaScript triggers.
