Cross-site scripting (XSS) attacks are the most common vulnerabilities in Web applications. An attacker embeds a client script (such as JavaScript) in a webpage. when a user browses the webpage, the script is executed in the browser of the user to achieve the target of the attacker. for example, attackers can obtain users' cookies, navigate to malicious websites, and carry Trojans.
