CWE: CWE-611 \u2014 Improper Restriction of XML External Entity Reference
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

Code:
	protected Element createXmlElementCopy() throws CoreException {

		try {
			synchronized (fLock) {
				Element newXmlEl = null;
				DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
				Document doc = builder.newDocument();
				synchronized (doc) {
					if (fElement.getParentNode().getNodeType() == Node.DOCUMENT_NODE) {
						Document baseDoc = fElement.getOwnerDocument();
						NodeList list = baseDoc.getChildNodes();
						for (int i = 0; i < list.getLength(); i++) {
							Node node = list.item(i);
							node = importAddNode(doc, node);
							if (node.getNodeType() == Node.ELEMENT_NODE && newXmlEl == null) {
								newXmlEl = (Element) node;
							}
						}

					} else {
						newXmlEl = (Element) importAddNode(doc, fElement);
					}
				}
				return newXmlEl;
