Apache Doris Updates Address Authentication Bypass and JDBC Code Execution

P2 — VALIDATE AND UPDATEModerate to Important · 7.5 (official CVSS); Not provided by the authority for advisories without a numeric scoreEXPLOITATION: NOT STATED

Quick Answer

The authority published CVE-2026-31377 for Apache Doris 2.0.0 through affected 4.0.x releases before 4.0.8 and 4.1.x before 4.1.4; the JDBC issue applies from 2.0.5 through 4.1.3. 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. Insufficient validation of the JDBC driver URL in Apache Doris allows a privileged user to achieve remote code execution on the FE. Affected deployments should be matched to the authority's exact scope and moved to the supported fixed release.

Confirm Scope And Apply The Supported Fix

What to do now: Inventory Apache Doris 2.0.0 through affected 4.0.x releases before 4.0.8 and 4.1.x before 4.1.4; the JDBC issue applies from 2.0.5 through 4.1.3, match the exact affected release or feature, apply the authority-supported fixed build or service remediation, validate the dependent workflow, and preserve evidence.

What Changed

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. Insufficient validation of the JDBC driver URL in Apache Doris allows a privileged user to achieve remote code execution on the FE.

What To Validate Now

  1. Inventory. Locate Apache Doris 2.0.0 through affected 4.0.x releases before 4.0.8 and 4.1.x before 4.1.4; the JDBC issue applies from 2.0.5 through 4.1.3 deployments, versions, enabled features, exposure paths, owners, and dependent services.
  2. Establish applicability. Compare each deployment with the authority's affected-version statement: Apache Doris 2.0.0 through affected 4.0.x releases before 4.0.8 and 4.1.x before 4.1.4; the JDBC issue applies from 2.0.5 through 4.1.3 Do not infer applicability from product family or severity alone.
  3. Remediate. Apply Apache Doris 4.0.8 or 4.1.4 as appropriate through the supported vendor or project channel, following the current advisory and change-control requirements.
  4. Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
  5. Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.

Operational Cautions

Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.

Evidence To Retain

  • Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
  • UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
  • Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
