Description
The Watu Quiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the HTTP Referer header in versions less than, or equal to, 3.4.4 due to insufficient input sanitization and output escaping when the "Save source URL" option is enabled. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an user accesses an injected page.
