Cross-Site Scripting (XSS) is a type of injection attack where malicious scripts are injected into otherwise trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser-side script, to a different end user.
Types of XSS: - Reflected XSS: The malicious script comes from the current HTTP request - Stored XSS: The malicious script comes from the website's database - DOM-based XSS: The vulnerability exists in client-side code rather than server-side code
Real-World Impact: - Session hijacking and cookie theft - Keylogging and credential harvesting - Defacement and phishing attacks - Malware distribution
