Advisory
Source description from Wordfence Intelligence, credited to Sanjay Das.
The WPCode plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on the ajax_auth_url, store_auth_key, and delete_auth functions in versions up to, and including, 2.0.6. This makes it possible for authenticated attackers with access to edit_posts, such as contributors, to retrieve and update the auth key for the WPCode library.
