The Watu Quiz plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘dn’, 'email', 'points', and 'date' parameters in versions up to, and including, 3.3.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Namaste! LMS WordPress plugin before 2.5.9.4 does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
