What it is

The Redirection for Contact Form 7 WordPress plugin from 2.2.7 before 3.2.11 does not prevent shortcodes in submitted form values from being executed when it substitutes those values into an action's settings and then processes those settings for shortcodes, allowing unauthenticated users to run any shortcode registered on the site and read its output.
