Advisory
Source description from Wordfence Intelligence, credited to LVT-tholv2k.
The Slivery Extender plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0.2 via the 'slider_theme_section' function. This is due to the use of call_user_func on one of the shortcode attributes. This makes it possible for authenticated attackers, with contributor access and above, to execute code on the server.
