If you cannot patch yet, restrict authenticated shell access to trusted users only and monitor for suspicious use of jdbc:* and jms:* commands. Avoid exposing the shell interface to untrusted users. Follow vendor advisories for updates on patches or official mitigations.
Description
CVE-2026-91048 is a critical privilege escalation vulnerability in Apache Karaf affecting versions prior to 4.4.12. The jdbc and jms shell commands lack proper ACL configuration, allowing any authenticated user, including those with only viewer role, to execute all jdbc:* and jms:* commands. This flaw enables an attacker to store a fully controlled JDBC URL that can trigger arbitrary code execution via JDBC driver URL parameters, bypassing admin role restrictions.
