## Description

The sermon-browser plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the embed code attached to a sermon on the Edit Sermon page in all versions up to, and including, 0.45.22, due to an HTML filter that allows the iframe srcdoc attribute. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the sermon page.
