Wp-Adv-Quiz <= 1.0.3 is vulnerable to Admin+ Stored XSS in Quiz Overview vulnerability

The Wp-Adv-Quiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a quiz title in all versions up to, and including, 1.0.3 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.
