The Newspaper WordPress theme before 12 does not sanitise a parameter before outputting it back in an HTML attribute via an AJAX action, leading to a Reflected Cross-Site Scripting.
El tema Newspaper WordPress anterior a la 12 no sanitiza un parámetro antes de devolverlo a un atributo HTML a través de una acción AJAX, lo que genera Reflected Cross-Site Scripting.
The Newspaper theme for WordPress is vulnerable to Reflected Cross-Site Scripting via an AJAX action in versions up to, and including, 11.5.1 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.
