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:
	public String getMemento() throws CoreException {
		Document document = null;
		Throwable ex = null;
		try {
			document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
			Element node = document.createElement(ELEMENT_NAME);
			document.appendChild(node);
			node.setAttribute(ATTR_DIRECTORY, getDirectory().toOSString());
			if (getAssociation() != null)
				node.setAttribute(ATTR_ASSOCIATION, getAssociation().toOSString());
			node.setAttribute(ATTR_SEARCH_SUBFOLDERS, String.valueOf(searchSubfolders()));
			return CDebugUtils.serializeDocument(document);
		} catch (ParserConfigurationException e) {
			ex = e;
		} catch (IOException e) {
			ex = e;
		} catch (TransformerException e) {
			ex = e;
		}
		abort(NLS.bind(InternalSourceLookupMessages.CDirectorySourceLocation_0, getDirectory().toOSString()), ex);
