Autenticación. (editor+) Vulnerabilidad de Cross-Site Scripting (XSS) reflejada en el complemento ExpressTech Quiz And Survey Master &lt;= 7.3.4 en WordPress.

The Quiz And Survey Master plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via several parameters in versions up to, and including, 7.3.4 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.
