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

Asked on Oct 28, 2025

Answer

To prevent cross-site scripting (XSS) attacks, you should sanitize and validate all user inputs and use security headers to protect your web application. Implementing Content Security Policy (CSP) is a key strategy.

<!-- BEGIN COPY / PASTE -->
    Content-Security-Policy: default-src 'self'; script-src 'self' 'nonce-<random>'; object-src 'none';
    <!-- END COPY / PASTE -->

Additional Comment:

Always escape user input on output to prevent malicious scripts from executing.
Use HTTP-only cookies to prevent access to cookies via JavaScript.
Regularly update your libraries and frameworks to patch known vulnerabilities.
