A malicious agent can supply a javascript: URI as the url argument of a Button component's functionCall action. When the user clicks the rendered button, arbitrary JavaScript executes in the victim application's browser origin, constituting a stored/reflected XSS.",

Um agente malicioso pode fornecer uma URI javascript: como o argumento url de uma ação functionCall de um componente Button. Quando o usuário clica no botão renderizado, o JavaScript arbitrário é executado no contexto do navegador da aplicação vítima, constituindo um XSS armazenado/refletido.",
