CVE-2026-63619: Apache Kylin missing authorization in metadata dump API

CVE-2026-63619 · Severity: info · Published 2026-10-16

Apache Kylin is a data analytics platform that provides metadata and system dump APIs. A missing authorization check in the metadata dump API allows unauthorized access to sensitive system metadata. The vulnerability primarily affects Kylin deployments exposed directly to the public internet, which is uncommon; most in-house deployments are protected by network perimeter controls.

Technologies: Apache Kylin. Vendors: Apache.

Technical details

A backend metadata dump API in Apache Kylin fails to enforce sufficient authorization checks and lacks proper path-confinement controls. An attacker with network access to the API can request sensitive metadata dumps without authentication or authorization verification, potentially exposing configuration and system information. A fix is available in version 5.0.5.
