wpa_field_info url access ?

I have been recently attacked by DDOS bots, today I noticed that there’s access attempts to my site with an URL as: /wp-admin/admin-ajax.php?action=wpa_field_info

Trying to enter on this URL I see the values of my honeypot settings (?)

Is this expected? or it is a security issue giving to anyone (bots?) access to my honeypot settings?

Thank you
Samuel
