How do you handle cross-site scripting (XSS) in Drupal?
Answer: To handle cross-site scripting (XSS) in Drupal, you should:
1. Use the built-in APIs: Always use Drupal’s built-in functions for outputting data, such as `Html::escape()` for escaping HTML output.
2. Sanitize user input: Validate and filter user input using Drupal’s form API, which automatically handles data sanitization.
3. Limit permissions: Control user roles and permissions to restrict who can enter content that may be rendered on the site.
4. Keep modules updated: Regularly update Drupal core and contributed modules to address known security vulnerabilities.
5. Use security modules: Consider using security modules like the Content Security Policy (CSP) to restrict and control resources loaded on your site.
Following these practices helps protect against XSS vulnerabilities in Drupal.
