An attacker with DDL rights on a connected MySQL/MSSQL datasource can create a column whose name contains a backtick (MySQL) or single quote (MSSQL) plus additional SQL; Budibase's schema introspection stores the name verbatim, and when a Budibase builder later renames that column through the UI (POST /api/tables with _rename.old), the embedded quote character terminates the identifier and the injected SQL is executed. Because the MySQL connection is opened with multipleStatements: true, stacked statements run as Budibase's datasource user, allowing arbitrary reads, writes, or destructive operations on the connected database outside Budibase's row/table permission model.
