## Description

The sermon-browser plugin for WordPress is vulnerable to Open Redirect via the 'url' parameter of the show request in all versions up to, and including, 0.45.22, due to missing validation of the redirect target. This makes it possible for unauthenticated attackers to redirect users to arbitrary external sites if they can get the user to click a crafted link.
