To prevent cross-site scripting (XSS) attacks, you should sanitize and validate user inputs, use security headers, and implement proper encoding. 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 security headers like Content-Security-Policy to restrict the sources of executable scripts, and ensure all user inputs are properly sanitized and encoded before rendering them in the browser.

Additional Comment:

Always encode data on output, especially when inserting untrusted data into HTML, JavaScript, or URLs.
Implement a strong Content-Security-Policy to control which resources can be loaded and executed.
Regularly update libraries and frameworks to incorporate the latest security patches.
