Cross-site Scripting (XSS) refers to client-side code injection attack wherein an attacker can execute malicious scripts into a legitimate website or web application. XSS occurs when a web application makes use of unvalidated or unencoded user input within the output it generates. The severity level of this vulnerability instance has been lowered to take into account that a victim would have to use a client that does not encode quote characters (", ') inside query strings.


Apply context-dependent encoding and/or validation to user input rendered on a page
