Remediation Steps

Follow the steps below to remediate this finding on WordPress.

1. Disable the Last-Modified and ETag headers if not needed for caching:

2. In functions.php:

   remove_action('wp_head', 'wp_generator');
   add_filter('wp_headers', function($headers) {
   unset($headers['Last-Modified']);
   unset($headers['ETag']);
   return $headers;
   });

3. Review theme and plugin output for raw timestamps in page source.
