EPSS

• CVE-2022-36110: 0.90% estimated exploitation activity in the next 30 days; percentile 59.62 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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: 1. docker-compose down 2. docker pull gravitl/netmaker:v0.15.1 3. docker-compose up -d For more information If you have any questions or comments about this advisory: Email us at info@netmaker.io This vulnerability was brought to our attention by @tweidinger

# Patch Next advisory brief: CVE-2022-36110

Advisory: Netmaker vulnerable to Insufficient Granularity of Access Control
IDs: CVE-2022-36110, GHSA-ggf6-638m-vqmg
Record: https://patchnext.com/advisories/cve-2022-36110 (revision 1, source checked 26 Oct 2026, 14:58 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/gravitl/netmaker 0.15.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/gravitl/netmaker: affected < 0.15.1; fixed in 0.15.1

## Suggested inspection (read-only)
- Go github.com/gravitl/netmaker: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/gravitl/netmaker.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-ggf6-638m-vqmg (GitHub-reviewed advisory GHSA-ggf6-638m-vqmg lists affected ranges: Go github.com/gravitl/netmaker >=0 <0.15.1)
