EPSS

• CVE-2022-23650: 1.59% estimated exploitation activity in the next 30 days; percentile 75.63 (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 There is a hard-coded cryptographic key in the code base which can be exploited to run admin commands on a remote server, if you know the address and username of the admin. This effects the server (netmaker) component, and not clients. Patches This has been patched in Netmaker v0.8.5, v0.9.4, and v0.10.0. If you are running these versions, the fix is to perform the following: 1. docker-compose down 2. docker pull gravitl/netmaker:( version ) 3. docker-compose up -d Additional Information If you are running any other version, you will need to upgrade to one of these three versions. If you have a special circumstance that requires running a different version, let us know and we may be able to build a custom patch.

# Patch Next advisory brief: CVE-2022-23650

Advisory: Use of Hard-coded Cryptographic Key in Netmaker
IDs: CVE-2022-23650, GHSA-86f3-hf24-76q4
Record: https://patchnext.com/advisories/cve-2022-23650 (revision 1, source checked 26 Oct 2026, 15:22 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.2)
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 0.9.4, 0.8.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/gravitl/netmaker: affected < 0.8.5; >= 0.9.0, < 0.9.4; fixed in 0.8.5, 0.9.4

## 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-86f3-hf24-76q4 (GitHub-reviewed advisory GHSA-86f3-hf24-76q4 lists affected ranges: Go github.com/gravitl/netmaker >=0 =0.9.0 <0.9.4)
