Low risk24th percentile - higher than 24% of all known CVEs
Summary
The Form Maker by 10Web plugin for WordPress up to version 1.15.44 is vulnerable to blind SQL injection via the '{username}' placeholder in a dynamic-choice field. Authenticated attackers with subscriber-level access can append additional SQL queries to extract sensitive information from the database.
Risk Assessment
The risk involves potential leakage of sensitive data from the WordPress database, including user data and content. However, exploitation requires additional conditions such as specific form configuration and the attacker changing their display_name.
Recommendation
It is recommended to update the plugin to the latest patched version immediately. Also, restrict user privileges and monitor accounts with low-level access.
Original NVD description (English source)
The Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to blind SQL Injection via '{username}' Placeholder in Dynamic-Choice Field WHERE Clause in all versions up to, and including, 1.15.44 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This requires that a form is configured with a DB-backed dynamic choice field whose WHERE template references the {username} placeholder, and the attacker must first set their own display_name to a SQL payload via the standard WordPress profile edit screen before triggering the fm_reload_input AJAX endpoint.
