Source Advisory Statement

### Impact Hardcoded DNS key usage has been found in Netmaker allowing unauth users to interact with DNS API endpoints. ### Patches 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". This will switch them to the patched users If users are using v0.18.0-0.18.5, they should upgrade to v0.18.6 or later. ### Workarounds If using 0.17.1, can just pull the latest docker image of backend and restart server. ### References Credit to Project Discovery, and in particular https://github.com/rootxharsh , https://github.com/iamnoooob, and https://github.com/projectdiscovery
