## Description

The WP2LEADS plugin for WordPress is vulnerable to SQL Injection via user-supplied map definitions (such as the 'from', 'joins', 'full_selects', comparison, 'keyBy' and virtual relationship fields) in all versions up to, and including, 3.5.6. This is due to table and column names being used in SQL without validation, comparison values being inserted without escaping, and the AJAX actions that accept these maps lacking capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries to existing queries and extract sensitive information from the database.
