CVE-2026-58319 Overview
CVE-2026-58319 affects Apache Doris, an open-source real-time analytical database. Certain Frontend (FE) HTTP REST administrative APIs are accessible without proper authentication [CWE-306: Missing Authentication for Critical Function]. An unauthenticated attacker with network access to the FE HTTP service can perform unauthorized administrative operations against the cluster.
Successful exploitation affects cluster integrity and availability. Attackers can trigger cluster instability or denial-of-service conditions against affected deployments. The issue impacts all Apache Doris releases prior to version 3.1.0. The Apache Doris project has published a fixed release addressing the missing authentication controls.
Critical Impact
Unauthenticated remote attackers with network access to the Doris FE HTTP endpoint can execute administrative operations, compromising cluster integrity and causing denial of service.
Affected Products
- Apache Doris versions prior to 3.1.0
- Apache Doris Frontend (FE) HTTP REST administrative APIs
- All deployments exposing the FE HTTP service to untrusted networks

Technical Details for CVE-2026-58319
Vulnerability Analysis
Apache Doris exposes a set of administrative REST endpoints through its Frontend (FE) HTTP service. These endpoints control cluster-level operations including configuration, node management, and metadata handling. In affected releases, a subset of these administrative APIs do not enforce authentication checks before processing requests.
An attacker who can reach the FE HTTP port over the network can issue administrative requests directly. No credentials, tokens, or session context are required. The vulnerability falls under CWE-306: Missing Authentication for Critical Function, which occurs when a critical resource requires proof of identity but does not enforce it.
The issue does not require user interaction, elevated privileges, or prior foothold in the environment. Exploitation targets integrity and availability of the cluster rather than data confidentiality.
Root Cause
The FE HTTP handler layer in Apache Doris versions prior to 3.1.0 omits authentication middleware on specific administrative REST routes. Requests arriving at those routes are dispatched to their handlers without validating the caller's identity or authorization scope.
Attack Vector
Exploitation requires network reachability to the Apache Doris FE HTTP service. An attacker sends crafted HTTP requests to the vulnerable administrative endpoints. Because authentication is absent, the FE processes the request as if it originated from an authorized administrator. Repeated or destructive operations can drive the cluster into an unstable state or halt availability.
See the Apache mailing list advisory and the OpenWall OSS Security notice for the coordinated disclosure details.
Detection Methods for CVE-2026-58319
Indicators of Compromise
- Unexpected HTTP requests to Apache Doris FE administrative REST paths originating from unknown or external source addresses
- FE process logs showing administrative operations without a preceding authentication event
- Sudden cluster configuration changes, node state transitions, or metadata modifications not tied to a scheduled operator action
- Unexplained FE restarts, backend node evictions, or degraded query availability
Detection Strategies
- Inspect FE audit and access logs for requests to administrative endpoints from IPs outside the operator management range
- Correlate administrative API activity with authenticated user sessions to identify orphaned or anonymous calls
- Baseline normal administrative request volumes and alert on deviations, particularly outside change windows
Monitoring Recommendations
- Forward Apache Doris FE HTTP access logs to a centralized logging or SIEM platform for retention and correlation
- Monitor the FE HTTP listener port for connections from segments that should not have administrative access
- Alert on cluster health signals such as unexpected node role changes, metadata version jumps, or FE leader transitions
How to Mitigate CVE-2026-58319
Immediate Actions Required
- Upgrade all Apache Doris deployments to version 3.1.0 or later as directed by the project advisory
- Restrict network access to the FE HTTP service so only trusted management hosts can reach administrative endpoints
- Audit FE logs for prior unauthenticated administrative activity before patching
- Rotate any cluster credentials or tokens that may have been exposed through prior administrative access
Patch Information
The Apache Doris project has released version 3.1.0, which enforces authentication on the affected FE HTTP REST administrative APIs. Operators should plan an upgrade path from any 2.x or earlier release to 3.1.0 or later. Refer to the Apache Doris advisory thread for release notes and upgrade guidance.
Workarounds
- Place the Apache Doris FE HTTP port behind a firewall or reverse proxy that enforces authentication and IP allow-listing
- Bind the FE HTTP listener to a management-only network interface rather than a publicly reachable address
- Use network segmentation to isolate Doris clusters from application tiers and general user networks until the upgrade is applied
