 "title": "Testimonial Slider <= 3.0.2 - Authenticated (Subscriber+) Missing Authorization to Post Menu Order Modification",
 "description": "The Testimonial plugin for WordPress is vulnerable to unauthorized modification of data via the tss-update-menu-order AJAX action in all versions up to, and including, 3.0.2, due to a missing capability check on the update_menu_order() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to reorder the menu_order values of arbitrary posts.",
