CodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing user-controlled condition values to be interpreted as SQL. This affects only the deleteBatch() code path. Regular delete() operations escape where() binds correctly. This issue is fixed in version 4.7.4.
