Apache Doris: Improper Authentication in Frontend HTTP API

Certain Apache Doris FE HTTP REST administrative APIs were accessible without proper authentication. An unauthenticated attacker with network access to the FE HTTP service could perform unauthorized administrative operations, potentially affecting cluster integrity and availability and leading to cluster instability or denial of service.

This issue affects Apache Doris versions prior to 3.1.0. Users are advised to upgrade to Apache Doris 3.1.0 or later.
