Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in WP Codeus Advanced Sermons allows Stored XSS.This issue affects Advanced Sermons: from n/a through 3.4.

The Advanced Sermons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘sermon_video_embed’ parameter in all versions up to, and including, 3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
