Summary

The JetFormBuilder WordPress plugin before 3.6.5.2 does not sanitize a request parameter before rendering it as message content, allowing unauthenticated users to execute arbitrary shortcodes registered on the site on any page displaying a form. Escaping is applied to that content before a later shortcode-expansion pass rather than after it, so the escaping can be bypassed.
