CVE-2025-66336Network attack vector

Metadata access via database-name SQL injection

Published Jun 22, 2026 · Updated Jun 22, 2026

SQL injection in Apache Doris MCP Server 0.1.0 through 0.6.0 allows remote authenticated users to access metadata outside their database scope. The metadata query path interpolates a caller-controlled database name directly into SQL and executes it without the caller's authorization context. Authentication is normally required, but disabling it exposes the same validation bypass to remote attackers; reported impact is limited to out-of-scope metadata access.
