Descriptions

The Email Subscription Popup WordPress plugin before 1.2.20 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

El complemento Email Subscription Popup de WordPress anterior a 1.2.20 no sanitiza ni escapa un parámetro antes de devolverlo a la página, lo que genera Cross-Site Scripting Reflejado que podría usarse contra usuarios con privilegios elevados, como el administrador.

The Email Subscription Popup plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'queueemails' parameter in all versions up to, and including, 1.2.19 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.
