A fix is available — apply it.

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
