Cross-site scripting, XSS, or web code injection, is an attack where attackers insert malicious code into a web form or into the URL of a web-based application. The malicious code is written in a scripting language like Javascript or PHP, and it can do anything – from deface the web page you’re trying to load to stealing your passwords or other login credentials. XSS exploits something that is an important aspect of the modern web. Namely that most web pages are put together immediately when the page is called up, sometimes using code included in the browser. And that makes it difficult to prevent such attacks.
