## Description

The Easy Property Listings plugin for WordPress is vulnerable to SQL Injection via the 'post_type' attribute of the [listing_search] shortcode in all versions up to, and including, 3.5.28. This is due to insufficient escaping of the user-supplied value and insufficient preparation of the existing SQL query: the epl_get_unique_post_meta_values() and epl_get_meta_values() functions pass post type values only through sanitize_text_field, which does not remove quotes, and then concatenate them into an IN() clause outside of $wpdb->prepare(). This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries to already existing queries that can be used to extract sensitive information from the database.
