CodeIgniter: SQL injection in Query Builder deleteBatch() when used with where() conditions
Impact
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.
Affected packages
| Ecosystem | Package | Affected | Fixed in |
