      "value": "Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any <wsdl:import> or <xsd:import> referenced from that top-level WSDL is handed off to WSDL4J, which does not disable DOCTYPE declarations or external entities. As a result, the protections applied to the top-level document do not extend to imported documents, leaving imported WSDL/XSD content vulnerable to XML External Entity (XXE) attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue."

Sin embargo, cualquier menor quewsdl:importmayor que o menor quexsd:importmayor que referenciado desde ese WSDL de nivel superior se entrega a WSDL4J, que no deshabilita las declaraciones DOCTYPE ni las entidades externas. Como resultado, las protecciones aplicadas al documento de nivel superior no se extienden a los documentos importados, dejando el contenido WSDL/XSD importado vulnerable a ataques de entidad externa XML (XXE). Se recomienda a los usuarios actualizar a las versiones 4.2.3 o 4.1.8 o 3.6.12, que solucionan este problema."
