PowerDNS Team reports:

CVE-2020-14196: An issue has been found in PowerDNS Recursor where the ACL applied to the internal
web server via webserver-allow-from is not properly enforced, allowing a remote attacker to send
HTTP queries to the internal web server, bypassing the restriction.

     In the default configuration the API webserver is not enabled. Only installations using a
     non-default value for webserver and webserver-address are affected.
