      "value": "The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'skin' attribute of the learn_press_courses shortcode in all versions up to and including 4.3.3. This is due to insufficient input sanitization and output escaping on the 'skin' shortcode attribute. The attribute value is used directly in an sprintf() call that generates HTML (class attribute and data-layout attribute) without any esc_attr() escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."

      "value": "El plugin LearnPress - WordPress LMS Plugin para WordPress es vulnerable a cross-site scripting almacenado a través del atributo 'skin' del shortcode learn_press_courses en todas las versiones hasta la 4.3.3 inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en el atributo 'skin' del shortcode. El valor del atributo se utiliza directamente en una llamada a sprintf() que genera HTML (atributo de clase y atributo data-layout) sin ningún escape esc_attr(). Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
