更新：微信表示上述2条语句无法禁止该漏洞，又双叒叕更新了官方SDK，加了以下语句（对于微信的这波操作，不知如何评价）： documentBuilderFactory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true); documentBuilderFactory.setFeature("http://xml.org/sax/features/external-general-entities", false); documentBuilderFactory.setFeature("http://xml.org/sax/features/external-parameter-entities", false); documentBuilderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); documentBuilderFactory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true); documentBuilderFactory.setXIncludeAware(false); documentBuilderFactory.setExpandEntityReferences(false);
