Unauthorized metadata dumps via missing access checks
Published Oct 16, 2026 · Updated Oct 16, 2026
Missing authorization in Apache Kylin 4 through 5.0.4 allows attackers to trigger unauthorized metadata dumps via a backend API. The metadata dump API lacks sufficient authorization and path confinement. Network access to the service is required; Apache identifies public exposure as the principal concern but does not specify required privileges or the resulting filesystem access.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
