Official description

Netmaker makes networks with WireGuard. Prior to versions 0.17.1 and 0.18.6, hardcoded DNS key usage has been found in Netmaker allowing unauth users to interact with DNS API endpoints. The issue is patched in 0.17.1 and fixed in 0.18.6. If users are using 0.17.1, they should run `docker pull gravitl/netmaker:v0.17.1` and `docker-compose up -d`.
