CVE-2026-67340: Improper Control of Generation of Code ('Code Injection') in ArcadeData arcadedb
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.
AI Analysis
Technical Summary
ArcadeDB before version 26.7.2 allows trigger scripts to access host Java classes in the java.lang package through Java.type because ScriptTriggerExecutor adds java.lang.* to the allowed packages. An authenticated user with UPDATE_SCHEMA permission can exploit this by creating a JavaScript trigger that calls java.lang.Runtime.getRuntime().exec() or ProcessBuilder, resulting in arbitrary OS command execution when the trigger is triggered.
Potential Impact
Successful exploitation enables an authenticated user with UPDATE_SCHEMA permission to execute arbitrary operating system commands on the host running ArcadeDB. This can lead to full system compromise or unauthorized control over the database server 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.
