Event handling is a critical aspect of web development, but it can also introduce security vulnerabilities if not implemented properly. From cross-site scripting (XSS) attacks to clickjacking, there are various risks associated with event handling code.

In this guide, we’ll explore security best practices in event handling to help you safeguard your web applications against potential threats.

Understanding Common Security Risks

Before diving into best practices, let’s briefly examine some common security risks associated with event handling:

• Cross-site Scripting (XSS): Attackers inject malicious scripts into web pages, which execute in the context of the user’s browser, leading to data theft or unauthorized actions.
• Cross-site Request Forgery (CSRF): Attackers trick users into unknowingly performing actions on a web application where they are authenticated, leading to unauthorized transactions.
• Clickjacking: Attackers overlay invisible elements on top of legitimate clickable elements, tricking users into performing unintended actions.
