Description

The Ultimate Member plugin for WordPress is vulnerable to Executing Arbitrary WordPress Shortcodes in versions up to, and including, 1.3.83. This is due to 'ultimatemember_frontend_modal' AJAX action allowing for the execution of the 'do_shortcode()' function. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
