ParameterPositionPathDescriptionCWE
run_sql_readonlyrequest body/mcp/queryThe /mcp/query endpoint accepts a run_sql_readonly request where the validator fails to prevent multi-statement execution. A caller can bypass the read-only contract by providing a read-only first statement followed by a side-effecting statement (e.g., RENAME TABLE, SET, KILL) because the backend connection uses CLIENT_MULTI_STATEMENTS.CWE-20
