Description

The sermon-browser plugin for WordPress is vulnerable to Stored Cross-Site Scripting via preacher, series and service names in all versions up to, and including, 0.45.22, due to insufficient output escaping on the Preachers and Series & Services admin pages, where the names are printed inside HTML attributes and javascript: links. Because these names can be set through the plugin's AJAX handler, which had no authorization check, this makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator opens or uses the affected admin pages.
