Cross-site scripting (XSS) Wiki


Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.

There are three major types of XSS attacks : 


  • Persistent XSS, where the malicious input originates from the website's database. 
  • Reflected XSS, where the malicious input originates from the victim's request. 
  • DOM-based XSS, where the vulnerability is in the client-side code rather than the server-side code.
