Description
The WP Encryption – One Click SSL / HTTPS & Free SSL Certificate, HTTPS Redirect, Security plugin for WordPress is vulnerable to Cross-Site Request Forgery via the wple_validate_ssl AJAX action in all versions up to, and including, 7.8.8.1, due to missing nonce validation in the wple_validate_nocp_ssl() function. This makes it possible for unauthenticated attackers to turn on the plugin's force HTTPS redirect and switch the site and home URLs to HTTPS through a forged request, if the site already serves a valid certificate and they can trick a site administrator into performing an action such as clicking on a link.
