CVE-2026-67356 is a privilege escalation vulnerability in ArcadeDB before version 26.7.3. The issue arises because the real LocalDatabase object is exposed to JavaScript trigger execution contexts with overly permissive host access settings. As a result, a user with schema-level administrative capabilities can invoke privileged security-management functionality from trigger code, including user-creation operations, without the intended permission checks being enforced. In practice, an attacker with UPDATE_SCHEMA permission can define a JavaScript trigger that executes in this privileged context and creates a server-wide administrative account, thereby escaping the authorization boundaries normally associated with schema administration.
