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

Asked on Oct 24, 2025

Answer

To prevent cross-site scripting (XSS) attacks on your website, you should implement a combination of input validation, output encoding, and security headers. These measures help ensure that malicious scripts cannot be executed in the context of your web pages.

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, you can use security headers like Content-Security-Policy to restrict the sources of executable scripts, and ensure all user inputs are properly validated and encoded before rendering them in the browser.

Additional Comment:

Always validate and sanitize user inputs on both client and server sides to prevent injection of malicious scripts.
Use output encoding libraries to ensure any data rendered in HTML, JavaScript, or CSS is safe.
Implement a strong Content-Security-Policy header to control which resources can be loaded and executed on your site.
