CVE-2026-67356: Improper Privilege Management in ArcadeData arcadedb
CVE-2026-67356 is a high-severity privilege escalation vulnerability in ArcadeData's arcadedb prior to version 26.7.3. The issue arises because the real LocalDatabase object is bound into JavaScript trigger contexts with excessive permissions (HostAccess.ALL). This allows schema administrators with UPDATE_SCHEMA permission to create triggers that execute JavaScript code capable of creating server-wide admin users without proper permission checks, thereby escalating their privileges beyond intended limits.
AI Analysis
Technical Summary
ArcadeDB versions before 26.7.3 improperly manage privileges by binding the LocalDatabase object into JavaScript trigger contexts with HostAccess.ALL. This binding enables schema administrators who have UPDATE_SCHEMA permission to bypass permission checks by invoking getSecurity().createUser() within triggers. Consequently, attackers can escalate privileges by creating server-wide administrative users, compromising the security model of the database.
Potential Impact
An attacker with UPDATE_SCHEMA permission can escalate privileges to full administrative rights by creating server-wide admin users through malicious JavaScript triggers. This compromises the integrity and security of the database system, potentially allowing unauthorized access and control over the database environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict UPDATE_SCHEMA permissions to trusted users only and monitor for suspicious trigger creation activities. Avoid deploying untrusted JavaScript triggers in the database environment.
