Answer with Explanation

Answer: To mitigate security risks in AJAX, especially in cross-origin requests:

  • Use CORS (Cross-Origin Resource Sharing) headers on the server to explicitly allow or restrict cross-origin requests.
  • Validate and sanitize user input on the server to prevent security vulnerabilities like SQL injection and cross-site scripting (XSS).
  • Avoid using sensitive information, such as API keys, directly in client-side code.
  • Implement secure authentication and authorization mechanisms to control access to sensitive resources.
