 "title": "Visual Portfolio, Photo Gallery & Post Grid <= 3.8.2 - Authenticated (Subscriber+) Missing Authorization via Multiple AJAX Actions",
 "description": "The Gallery by Visual Portfolio plugin for WordPress is vulnerable to unauthorized access via the vp_dynamic_control_callback and vp_find_oembed AJAX actions in all versions up to, and including, 3.8.2, due to missing capability checks on handlers that only verified the 'vp-ajax-nonce' nonce, which is printed on every admin page, including the profile page any logged-in user can open. This makes it possible for authenticated attackers, with subscriber-level access and above, to search the titles of draft, pending and scheduled posts of any author, list post types and terms, and make the site perform oEmbed lookups.",
