The HTML-injection may trick authenticated users to follow the link. If the Link gets clicked, Javascript code can be executed. The vulnerability is due to insufficient sanitization of the \"data-frmverify\" tag for links in the web-based entry inspection page of affected systems. A successful exploitation incomibantion with CSRF could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. These actions include stealing the users account by changing their password or allowing attackers to submit their own code through an authenticated user resulting in Remote Code Execution. If an authenticated user who is able to edit Wordpress PHP Code in any kind, clicks the malicious link, PHP code can be edited."}, {"lang": "es", "value": "El plugin Formidable Form Builder de WordPress versiones anteriores a 4.09.05, permite inyectar determinadas etiquetas HTML como ,,,<a rel=\"nofollow\"> y.Esto podr\u00eda permitir a un atacante remoto no autenticado explotar una inyecci\u00f3n HTML al inyectar un enlace malicioso. La inyecci\u00f3n HTML puede enga\u00f1ar a usuarios autenticados para que sigan el enlace. Si se hace clic en el Enlace, es posible ejecutar c\u00f3digo Javascript.
