      "value": "The WPUpper Share Buttons plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.51. This is due to missing or incorrect nonce validation on the 'save_custom_css_request' function. This makes it possible for unauthenticated attackers to inject custom CSS to modify a site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link."

Esto se debe a una validaci\u00f3n de nonce incorrecta o faltante en la funci\u00f3n 'save_custom_css_request'. Esto hace posible que atacantes no autenticados inyecten CSS personalizado para modificar un sitio a trav\u00e9s de una solicitud falsificada, siempre que puedan enga\u00f1ar a un administrador del sitio para que realice una acci\u00f3n como hacer clic en un enlace."
