Can a website still be vulnerable to *Reflected XSS even when angle brackets are HTML encoded?* In this PortSwigger Web Security Academy lab, we'll investigate how a seemingly harmless search query becomes a JavaScript injection point. In this practical **Reflected XSS tutorial**, I'll walk through the lab step by step, inspect the reflected input, analyze the JavaScript context, and use Burp Suite to understand how an attacker can escape from a JavaScript string and execute JavaScript. This is an important Cross-Site Scripting (XSS) example because it demonstrates why HTML encoding alone is not enough to secure data inserted into JavaScript contexts. 🔥 *What you'll learn in this video:* What is Reflected XSS and how does it work? How a reflected search query can create an XSS vulnerability How to identify JavaScript string injection points How to analyze requests using Burp Suite Why HTML-encoded angle brackets do not always prevent XSS How to break out of a JavaScript string How to demonstrate JavaScript execution in the lab How to understand this XSS vulnerability from a security testing perspective 🧪 *Lab Details:* Platform: PortSwigger Web Security Academy Lab: Reflected XSS into a JavaScript string with angle brackets HTML encoded Vulnerability: Reflected Cross-Site Scripting (XSS) Context: JavaScript string Tool: Burp Suite Series: XSS Lab 9 you can search: Reflected XSS Explained!
