A cross-site scripting vulnerability (also known as XSS) occurs when a web app allows a user to insert their own code into a webpage that can be seen by other users. The attack happens when a malicious user is able to insert malicious code into the web app. For example: an attacker could add some malicious JavaScript code that would render on other users' browsers. The malicious code could access victims' cookies to carry out a session hijack attack.
