WP Content Copy Protection & No Right Click <= 3.3 - Cross-Site Request Forgery to Arbitrary Plugin Installation/Activation

The WP Content Copy Protection & No Right Click Plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.3. This is due to missing or incorrect nonce validation on the 'cp_plugins_do_button_job_later_callback' AJAX action. This makes it possible for unauthenticated attackers to install and activate other plugins via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
