Missing authorization in XWiki Platform allows remote authenticated users with SCRIPT right to read files from the deployed WAR. XWiki#invokeServletAndReturnAsString passes an attacker-chosen path to a RequestDispatcher and returns the buffered servlet or JSP output. SCRIPT right is required; exposed files include xwiki.cfg and xwiki.properties, allowing disclosure of stored configuration data.
