Wordpress Ultimate Member Plugin Unauthenticated Remote Code Execution Exploit Update

The vulnerability allows to an unauthenticated attacker to register as an administrator and take full control of the website. The problem occurs with the plugin registration form. In this form it's possible to change certain values for the account to be registered. This includes the "wp_capabilities" value, which determines the user's role on the website. This update adds a print in the module output window.
