CVE-2026-63619: Apache Kylin: Missing authorization and path-confinement on system meta dump
Missing Authorization vulnerability in Apache Kylin. A backend metadata dump API misses the enough authorization and the path-confinement. Impact most to the kylin services that are directly exposed to public network, which is not common. In-house kylin deployments are mostly not impacted.
This issue affects Apache Kylin: from 4 through 5.0.4.
Users are recommended to upgrade to version 5.0.5, which fixes the issue.
