Form Maker by 10Web < 1.15.41 - Authenticated (Administrator+) SQL Injection via 'ip_search' Parameter

Description

The Form Maker by 10Web plugin for WordPress is vulnerable to SQL Injection via the 'ip_search', 'startdate', 'enddate', 'username_search', and 'useremail_search' parameters in all versions up to, and including, 1.15.40. This is due to the `WDW_FM_Library::validate_data()` method calling `stripslashes()` on user input (removing WordPress's `wp_magic_quotes()` protection) and the `FMModelSubmissions_fm::get_labels_parameters()` function directly concatenating user-supplied values into SQL queries without using `$wpdb->prepare()`. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Additionally, the Submissions controller skips nonce verification for the `display` task, which means this vulnerability can be triggered via CSRF by tricking an administrator into clicking a crafted link.
