XSS in HTML attributes

Learn how to find and exploit a vulnerability that is one of the most common vulnerabilities, easy to find, and yet very dangerous. Hackerone ranked XSS the #1 bug bounty vulnerability of 2021.

XSS (Cross-Site Scripting) vulnerabilities are both common and serious. For example, HackerOne has listed XSS as the number one vulnerability on their top 10 vulnerabilities list.

Vulnerability management is therefore extremely important, whether you are a penetration tester, a security consultant, a developer, or a bounty hunter!
