Description TEJ RATHI 2023-07-03 05:10:52 UTC 
Coredns mishandling of CI bit: CD bit response is cached and served later

What happened:
If CD bit is set in query, it disables validation at remote server

What you expected to happen:
CD queries may pass, but the same answer must not be served to queries without CD bit set
