Description SMASH SMASH 2023-10-17 08:46:39 UTC 
Grafana is an open-source platform for monitoring and observability. 

In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance doesn’t call specific hosts.

However, the restriction can be bypassed used punycode encoding of the characters in the request address.
