CVE-2026-67340Public exploitNetwork attack vectorHinoki check available

Authenticated OS command execution via JavaScript triggers

Published Aug 1, 2026 · Updated Aug 1, 2026

Code injection in Arcade Data ArcadeDB before 26.7.2 allows remote authenticated users to execute OS commands through JavaScript triggers. ScriptTriggerExecutor adds java.lang.* to the GraalVM host-class allow-list, so Java.type resolves Runtime or ProcessBuilder despite process restrictions. UPDATE_SCHEMA permission is required to create the trigger; when it fires, the command runs with the ArcadeDB process account's operating-system access.
