CVE-2026-67340 PUBLISHED

ArcadeDB before 26.7.2 Remote Code Execution via Trigger Scripts

Assigner: VulnCheck
Reserved: 29.07.2026 Published: 01.08.2026 Updated: 01.08.2026

ArcadeDB before 26.7.2 (arcadedb-engine) allows trigger scripts to look up host classes in java.lang. (via Java.type) because ScriptTriggerExecutor adds java.lang. to the allowed packages. An authenticated user with UPDATE_SCHEMA permission can create a JavaScript trigger that invokes java.lang.Runtime.getRuntime().exec() (or ProcessBuilder), achieving OS command execution when the trigger fires.
