Technical details
The ScriptTriggerExecutor class improperly allows trigger JavaScript code to access the full java.lang.* package namespace via the Java.type() method. A user with UPDATE_SCHEMA permission can create a CREATE TRIGGER statement with embedded JavaScript that invokes java.lang.Runtime.getRuntime().exec() or java.lang.ProcessBuilder to execute OS commands. The vulnerability stems from adding java.lang.* to the allowedPackages list combined with HostAccess.ALL permissions, bypassing the reflection denylist since Java.type performs host-class lookup rather than reflection. The trigger fires automatically when database events occur, executing the attacker's payload. Fix available in version 26.7.2 which removes java.lang.* from the allowed package list.
