CVE-2026-67340 is a high-severity flaw (CVSS 7.2) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- CISA SSVC: automatable with total technical impact
A fixed release or distro patch exists.
