JCH Optimize <= 3.2.2 - Authenticated (Administrator+) Stored Cross-Site Scripting via admin settings

The JCH Optimize plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 3.2.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator-level access, and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
