我使用Quttera扫描了2个Wordpress网站，以确定它们是否干净。让我们分别称这些博客为website1.com和website2.com。我在website1.com上找到了5个隐藏的iframe：
iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"http:\/\/www.website1.com\/about\/embed\/\" width=\"600\" height=\"338\" title=\"Embedded WordPress Post\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" class=\"wp-embedded-content\"
iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"http:\/\/www.website1.com\/contact-us\/embed\/\" width=\"600\" height=\"338\" title=\"Embedded WordPress Post\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"class=\"wp-embedded-content\"
iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"http:\/\/www.website1.com\/privacy-policy\/embed\/\" width=\"600\" height=\"338\" title=\"Embedded WordPress Post\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" class=\"wp-embedded-content\"
iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"http:\/\/www.website1.com\/sitemap\/embed\/\" width=\"600\" height=\"338\" title=\"Embedded WordPress Post\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" class=\"wp-embedded-content\"
iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"http:\/\/www.website1.com\/links\/embed\/\" width=\"600\" height=\"338\" title=\"Embedded WordPress Post\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" class=\"wp-embedded-content\"
website1.com和website2.com都使用相同的Wordpress主题。所以我真的不知道这些iframe来自哪里。
