Advisory
Source description from Wordfence Intelligence, credited to stealthcopter.
The ajax-extend plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0 via the ajax_operation function. This is due to plugin not properly restricting user input to call_user_func(). This makes it possible for unauthenticated attackers to execute code on the server.
