Advisory
Source description from Wordfence Intelligence, credited to Luka Sikic.
The Simple Social Media Share Buttons plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the download(), import(), and download_help() functions in versions 2.0.4 - 2.0.21. This makes it possible for authenticated attackers with minimal permissions, such as a subscriber, to update arbitrary options on the site that can be used to register a new administrative user account.
