If you cannot patch yet, restrict 'manager' role assignments to trusted users only and monitor for suspicious configuration changes. Avoid exposing the management interfaces to untrusted networks. Follow official Apache Software Foundation advisories for updates and patches.
Description
CVE-2026-91012 is a critical directory traversal vulnerability in Apache Karaf's configuration management component. It allows users with the 'manager' role to write configuration files to arbitrary locations writable by the Karaf process, bypassing intended access controls. This can lead to privilege escalation by modifying files reserved for the 'admin' role, enabling takeover of the container. The vulnerability arises from insufficient validation of file paths derived from user-supplied input in ConfigRepositoryImpl.update() and createFactoryConfiguration().
