Episode 77: Cross-Site Scripting Vulnerabilities (XSS)

Cross-site scripting, or XSS, is one of the most common and dangerous web application vulnerabilities. In this episode, we break down the three primary types—reflected, persistent, and DOM-based XSS—and explain how each one works, what it targets, and how attackers use it to steal session cookies, impersonate users, or inject malicious content into trusted pages.

We also walk through how these attacks are identified in scans and logs, how they can be remediated through input validation and output encoding, and how they align with OWASP Top Ten categories. You'll leave this episode with a clear understanding of why XSS is such a high-priority concern for developers and analysts alike—and how to detect and explain it clearly on the CySA+ exam and in your professional reporting.
