Budibase (@budibase/server) before 3.45.0 builds MySQL and MSSQL column-rename DDL in packages/backend-core/src/sql/sqlTable.ts by interpolating identifiers directly into a raw query string (backtick-quoted for MySQL, a single-quoted sp_rename literal for MSSQL) without applying the project's quoteMySqlIdentifier / quoteSqlServerIdentifier helpers. 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. Fixed in 3.45.0.
