CVE-2026-67340 is a remote code execution vulnerability in ArcadeDB before version 26.7.2 in the arcadedb-engine component. The flaw is caused by ScriptTriggerExecutor permitting trigger scripts to resolve host classes from the java.lang package via Java.type. Because java.lang.* is included in the allowed packages, an authenticated user with UPDATE_SCHEMA permission can create a malicious JavaScript trigger that accesses dangerous Java runtime functionality such as Runtime or ProcessBuilder. When the trigger executes, the attacker can cause operating system commands to run in the context of the ArcadeDB process.
