CVE-2025-66336: Apache Doris MCP Server: SQL injection leading the authentication bypass
Apache Doris MCP Server contains a SQL injection vulnerability in a metadata query path. A user-controlled database name is directly interpolated into a SQL query, and the query is executed without passing the caller's authorization context. This may allow an authenticated attacker, or an anonymous attacker if authentication is disabled, to bypass SQL security validation and access metadata outside the intended database scope.
Affected users are recommended to upgrade to Doris version 0.6.1 or later, which fixes the issue.
Security readout for executives and security teams
Apache Doris MCP Server 0.1.0 has a high-severity SQL injection flaw in a metadata lookup. An attacker with access to the server, or anyone if authentication is disabled, may bypass SQL security validation and view metadata outside the intended database scope. Exposure is limited to Apache Doris MCP Server deployments running version 0.1.0 of doris-mcp-server. Risk is higher where the MCP server is reachable by untrusted users, broadly exposed internally, or running with authentication disabled. Prioritize remediation for any reachable Apache Doris MCP Server 0.1.0 deployment. The main business risk is unauthorized metadata access and security-control bypass, especially in environments where database metadata reveals sensitive structure or operational details. Mitigation focus: Upgrade Apache Doris MCP Server to version 0.6.1 or later.; Confirm authentication is enabled on all MCP server deployments.; Restrict MCP server access to trusted networks and identities..

Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
