What is XSS?

Cross-site scripting (XSS) is the name that refers to a particular weakness in web application security. The weakness is caused by incorrect handling of data input, such as cookie data, URL, or HTTP request parameters. The issue with the weak input sanitization is that some of the data may be returned to the user and perform custom script execution.
