Episode 72 — XSS Types and Outcomes

This episode explains cross-site scripting as executing attacker-controlled script in a user’s browser context, then teaches you to distinguish reflected, stored, and DOM-based XSS from scenario cues. You’ll learn reflected XSS as immediate response-based reflection, stored XSS as persistence that affects multiple users over time, and DOM-based XSS as browser-side logic creating the weakness during runtime. We’ll cover practical outcomes like session theft, user action manipulation, and in-app phishing, and why safe confirmation uses benign proof rather than harmful payloads. You’ll practice interpreting scenarios involving comments, profile fields, search parameters, or client-side scripts, then choosing the most likely XSS type and the best mitigation concepts, including output encoding, careful input handling, and content security policy as a defense-in-depth layer. By the end, you’ll be able to select answers that match the right XSS type, articulate the user impact clearly, and recommend fixes that address root cause rather than simply blocking characters.
