In this video we solve PortSwigger XSS Lab 7: Reflected XSS into attribute with angle brackets HTML-encoded — a professional, legal walkthrough focused on understanding how user-controlled input placed inside HTML attributes can lead to XSS even when angle brackets are HTML-encoded.

What this video covers:

The difference between reflected, stored, and DOM XSS.

Why placing user input inside HTML attribute contexts (e.g., value, href, title) changes the exploitation approach.

How HTML-encoding of angle brackets affects payload delivery and common bypass techniques at a conceptual level.

A safe, step-by-step lab walkthrough in a controlled environment showing how to identify the vulnerable sink, verify impact, and confirm remediation.

Defensive recommendations for developers: proper context-aware output encoding, use of safe APIs, CSP, and input validation to prevent attribute-based XSS.

Who this is for: beginners learning web security, students of PortSwigger Academy, bug bounty newcomers, and developers who want to harden their apps.

Legal & Ethical: All techniques are demonstrated strictly for educational and defensive purposes in a controlled lab environment. Do not test these techniques against systems you do not own or have explicit permission to test.
