How can I protect my website from cross-site scripting attacks?

Asked on Oct 21, 2025

Answer

To protect your website from cross-site scripting (XSS) attacks, you should implement a combination of input validation, output encoding, and use of security headers. These measures help prevent malicious scripts from being executed in your users' browsers.

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

Additional Comment:

Always validate and sanitize user inputs to prevent harmful data from being processed.
Use output encoding to ensure data is safely rendered in the browser.
Implement the Content-Security-Policy header to restrict sources of executable scripts.
Avoid using 'unsafe-inline' in CSP unless absolutely necessary, as it can weaken the policy.
