XSS Attack (Cross-Site Scripting attack)

A Cross-Site Scripting (XSS) attack refers to a type of security vulnerability in web applications that occurs when an attacker injects malicious scripts (usually JavaScript) into web pages viewed by other users. These malicious scripts execute within the context of the victim’s web browser, allowing the attacker to steal sensitive data, manipulate web content, or perform actions on behalf of the victim. XSS attacks are a common web security threat, and web developers use various techniques to prevent them.
