Descriptions

The WP Mailster plugin before 1.5.5 for WordPress has XSS in the unsubscribe handler via the mes parameter to view/subscription/unsubscribe2.php.

El plugin WP Mailster en versiones anteriores a la 1.5.5 para WordPress contiene XSS en el manipulador unsubscribe mediante el parámetro mes en view/subscription/unsubscribe2.php.

The WP Mailster plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'mes' parameter found in the 'view/subscription/unsubscribe2.php' file in versions up to 1.5.5 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.
