Technical details
The WP Directory Kit plugin before version 1.5.5 contains a SQL injection vulnerability in its authenticated AJAX action `ajax_save_order` within the `wdk_fields` page. The `data_fields_list` parameter is not sanitized or escaped before being used in a SQL statement. The vulnerable AJAX endpoint lacks authorization and nonce checks, allowing any authenticated user, including a Subscriber (the lowest privilege level), to execute arbitrary SQL queries. Attackers can perform blind time-based SQL injection attacks to extract database contents such as password hashes and other sensitive data. The vulnerability is fixed in version 1.5.5.
