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:
	private ByteArrayOutputStream write(ICStorageElement element) throws CoreException {
		Document doc = ((InternalXmlStorageElement) element).fElement.getOwnerDocument();
		XmlUtil.prettyFormat(doc);

		ByteArrayOutputStream stream = new ByteArrayOutputStream();
		try {
			Transformer transformer = TransformerFactory.newInstance().newTransformer();
			transformer.setOutputProperty(OutputKeys.METHOD, "xml"); //$NON-NLS-1$
			transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); //$NON-NLS-1$
			// Indentation is done with XmlUtil.prettyFormat(doc)
			transformer.setOutputProperty(OutputKeys.INDENT, "no"); //$NON-NLS-1$
			DOMSource source = new DOMSource(doc);
			StreamResult result = new StreamResult(stream);
			transformer.transform(source, result);

			return stream;
		} catch (TransformerConfigurationException e) {
			throw ExceptionFactory.createCoreException(e);
		} catch (TransformerException e) {
			throw ExceptionFactory.createCoreException(e);
		}
