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.\n\n\n\nThis 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.\n\n\n\n\nUsers are recommended to upgrade to a fixed release (4.0.8 or 4.1.4), which fixes the issue.","published":"2026-09-23T09:17:08.000Z","lastModified":"2026-09-23T17:58:27.000Z","status":"Awaiting Analysis","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-287"],"affected":[],"epss":{"score":0.00672,"percentile":0.51807,"date":"2026-10-26","history":[{"date":"2026-09-23","score":0.00647,"percentile":0.49622}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.67%).
