Real-World Exposure
github.com/gravitl/netmakerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Improper Authorization functions leads to non-privileged users running privileged API calls. If you have added users to your Netmaker platform who whould not have admin privileges, they could use their auth token to run admin-level functions via the API.
In addition, differing response codes based on function calls allowed non-users to potentially brute force the determination of names of networks on the system.
Patches
This problem has been patched in v0.15.1. To apply:
- docker-compose down
- docker pull gravitl/netmaker:v0.15.1
- docker-compose up -d

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gravitl/netmaker, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/gravitl/netmaker to 0.15.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-36110 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
