The Total theme for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in versions up to, and including, 2.2.1 due to insufficient output escaping when rendering the_title() inside HTML attribute context in the home blog section template. 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. Exploitation requires the malicious post to be published and displayed with a featured image in the Home Page blog section.
