Arbitrary SQL execution via interpolated schema argument
Published Apr 2, 2026 · Updated Apr 2, 2026
SQL injection in mcp-data-vis allows remote attackers to read, modify, or delete SQLite data through the create_table MCP tool. The create_table handler interpolates the unvalidated schema argument into a CREATE TABLE string and passes it to SQLite db.exec(), which accepts injected statements. Exploitation requires an MCP deployment that exposes the database handler to untrusted callers; successful injection affects data in the target SQLite database.
