CVE-2025-66335Network attack vector

SQL injection via unvalidated query context identifiers

Published Apr 20, 2026 · Updated Apr 20, 2026

SQL injection in Apache Doris MCP Server before 0.6.1 allows remote attackers to execute unintended SQL through the MCP query interface. The exec_query_for_mcp path placed unvalidated catalog_name and db_name values inside USE statements, while validation parsed only the first supplied statement. Reachability requires access to an MCP query tool and a configured Doris connection; successful injection can read data visible to the connected Doris account.
