The Ultimate XSS Scanner & Parameter Analysis Tool for Bug Hunters

Understanding XSS Attacks

Cross-site scripting (XSS) is one of the most common web vulnerabilities, allowing attackers to inject malicious scripts into web applications. These scripts can steal user data, hijack sessions, deface websites, or even perform actions on behalf of unsuspecting users. XSS vulnerabilities exist due to improper handling of user input, making it crucial for developers and security professionals to detect and mitigate them before attackers exploit them.
