Mitigation

Doing a transform in JAXP requires the use of a 'javax.xml.transform.TransformerFactory'. If the FEATURE_SECURE_PROCESSING feature is set to 'true', it mitigates this vulnerability. Eg: TransformerFactory factory = TransformerFactory.newInstance(); factory.setFeature(javax.xml.XMLConstants.FEATURE_SECURE_PROCESSING, true);
