Cross-Site Scripting (XSS) is a technique used to embed malicious content into the resulting web page. As such, it is pertinent to note that this class of attack targets end-users rather than the web application itself. When this attack is considered “reflected”, a user requests a web page with a payload which is embedded within a crafted hyperlink or a malicious page.
Certain AJAX callbacks in CiviCRM did not properly encode their outputs - making them vulnerable to cross-site scripting attacks.
