Descriptions

The WP Fastest Cache WordPress plugin before 0.9.5 is lacking a CSRF check in its wpfc_save_cdn_integration AJAX action, and does not sanitise and escape some the options available via the action, which could allow attackers to make logged in high privilege users call it and set a Cross-Site Scripting payload

El complemento de WordPress WP Fastest Cache anterior a 0.9.5 carece de una verificación CSRF en su acción AJAX wpfc_save_cdn_integration, y no sanitiza ni escapa algunas de las opciones disponibles a través de la acción, lo que podría permitir a los atacantes hacer que los usuarios registrados con altos privilegios lo llamen y configuren un payload de cross site scripting

The WP Fastest Cache plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions before 0.9.5. This is due to missing or incorrect nonce validation on the wpfc_save_cdn_integration function. This makes it possible for unauthenticated attackers to perform stored cross-site scripting attacks via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
