What is CVE-2026-93598?
CVE-2026-93598 is a high-severity vulnerability in ArcadeData arcadedb, published on 18 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
ArcadeDB (Maven artifact com.arcadedb:arcadedb-engine) through 26.8.1 contains an incomplete deny-list in the polyglot script sandbox: com.arcadedb.query.polyglot.HostClassLookupFilter.DENIED lists java.util.ResourceBundle as a bare class name, which is matched by exact equality and therefore does not cover its subclasses, while ScriptTriggerExecutor.ALLOWED_PACKAGES permits java.util.*. A user with the UPDATE_SCHEMA privilege (sufficient to create or alter a JavaScript trigger; no server-admin rights required) can reference java.util.PropertyResourceBundle or java.util.ListResourceBundle and invoke the inherited static ResourceBundle.getBundle(String) to read .properties resources from the application classpath, which the sandbox (IOAccess.NONE, with java.io.**, java.nio.** and java.net.** denied) is intended to make unreachable. This can disclose packaged application configuration such as database credentials and API keys; the advisory states the issue does not provide arbitrary host filesystem read or remote code execution. Fixed in 26.9.1.
Weakness: CWE-184
