Cross Site Scripting

The video tutorial explains cross-site scripting (XSS), a vulnerability allowing attackers to inject malicious code into web applications. It covers two main types: reflected XSS, which is non-persistent and occurs when a script is reflected off a web application, and stored XSS, which is persistent and involves injecting a script into a web application. The tutorial provides examples of both types and discusses prevention methods, such as using secure frameworks, input sanitization, and content security policies.
