How can I prevent cross-site scripting attacks on my website?

Asked on Nov 03, 2025

Answer

To prevent cross-site scripting (XSS) attacks, you should sanitize user inputs, use Content Security Policy (CSP), and implement secure headers. These measures help ensure that malicious scripts cannot be executed in your web application.

Example Concept: Cross-site scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. To mitigate XSS, use Content-Security-Policy to restrict the sources of scripts, X-XSS-Protection to enable browser-based XSS filters, and ensure all user inputs are properly sanitized and encoded before rendering.

Additional Comment:

Always validate and sanitize user inputs on both client and server sides.
Use libraries or frameworks that automatically escape outputs, such as React or Angular.
Regularly update your software and dependencies to patch known vulnerabilities.
