Classpath credential disclosure via ResourceBundle subclass bypass
Published Sep 18, 2026 · Updated Sep 18, 2026
Information disclosure in ArcadeDB 26.8.1 and earlier allows remote authenticated users to read classpath resources through JavaScript triggers. HostClassLookupFilter compares the bare ResourceBundle deny-list entry by exact class name, while the java.util allow-list admits subclasses that inherit getBundle. UPDATE_SCHEMA permission and a known or guessed bundle name are required; exposure is limited to packaged classpath resources, not host files or code execution.
