CVE-2013-6430 is a cross-site scripting vulnerability in Spring MVC in Spring Framework versions before 3.2.2. The JavaScriptUtils.javaScriptEscape method does not properly escape Unicode line-separator and paragraph-separator characters or left and right angle brackets. Applications that rely on this method to escape user-controlled content before rendering it in HTML5 JavaScript contexts may permit script injection.
