CVE-2026-91048Network attack vectorHinoki check available

Authenticated code execution via unguarded JDBC commands

Published Sep 29, 2026 · Updated Sep 29, 2026

Missing authorization in Apache Karaf before 4.4.12 allows remote authenticated users to execute code through the jdbc:ds-create shell command. SecuredSessionFactoryImpl allows commands without a matching ACL, while jdbc:ds-create stores an unchecked JDBC URL that pax-jdbc-config turns into a live data source. A viewer-role shell session is sufficient when an installed JDBC driver executes code from connection URL parameters; the missing ACL also exposes jms commands.
