CVE-2026-96443

In Apache Doris, certain 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.

An Improper Authentication vulnerability in the Apache Doris Frontend (FE) meta service allows an unauthenticated remote attacker to access internal metadata service endpoints. The affected endpoints relied on client-supplied node information for authentication without providing sufficient authentication of the requesting party. Under certain network configurations, a remote attacker may be able to bypass the intended access control and access internal FE metadata interfaces, potentially exposing sensitive cluster information. This issue affects Apache Doris: from 2.0.0 through 2.0.*, from 2.1.0 through 2.1.*, from 3.0.0 through 3.0.*, from 3.1.0 through 3.1.*, from 4.0.0 before 4.0.8, and from 4.1.0 before 4.1.4. Versions 1.2.x and earlier are not affected by this header-trust vulnerability.

An Incorrect Authorization vulnerability in Apache Doris allows an authenticated user to bypass privilege checks and access or modify data they are not authorized to. This issue affects Apache Doris versions 3.1.0 through 3.1.*, 4.0.0 through 4.0.7, and 4.1.0 through 4.1.3.

An Incorrect Authorization vulnerability in Apache Doris allows an authenticated user to bypass privilege checks and access data they are not authorized to read, resulting in unauthorized disclosure of information. This issue affects Apache Doris versions 2.0.0 through 2.1.*, 3.0.0 through 3.0.*, 4.0.0 before 4.0.8, and 4.1.0 before 4.1.4.
