CVE-2026-31377

Summary

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.

Users are recommended to upgrade to a fixed release (4.0.8 or 4.1.4), which fixes the issue.
