The WP-Members Membership Plugin plugin for WordPress is vulnerable to SQL Injection via the 'order_by' attribute of the [wpmem_user_membership_posts] shortcode in all versions up to, and including, 3.5.5.1. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
