Can you explain how to protect a CMS from cross-site scripting (XSS) attacks?

Answer: To protect a CMS from XSS attacks, you can:

1. Input Validation: Validate and sanitize user inputs to ensure they don’t contain malicious scripts.
2. Output Encoding: Use proper encoding when displaying user-generated content to prevent execution of scripts.
3. Content Security Policy (CSP): Implement CSP headers to restrict the sources of executable scripts.
4. Use Security Libraries: Utilize libraries and frameworks that automatically handle XSS protection.
5. Regular Updates: Keep your CMS and plugins updated to patch known vulnerabilities.
6. Educate Users: Train users on safe practices and report suspicious behavior.

Implementing these measures can significantly reduce the risk of XSS attacks on your CMS.
