How to Prevent Cross-Site Scripting (XSS) Attacks

Cross-Site Scripting is a web-based attack performed on vulnerable web applications where an attacker can create a malicious link to inject unwanted executable JavaScript into a website.

A Cross-Site Scripting attack involves executing malicious code on a victim’s browser. Code is executed on the client side rather than on the server side.

XSS usually gets inserted through a webpage using a web form or hyperlink. This code can be used with client-side languages such as JavaScript, PHP, HTML, etc.
