CVE-2022-36110 — netmaker
HIGHCVE-2022-36110 is a high-severity (CVSS 8.8) CWE-285 vulnerability in github.com/gravitl/netmaker. A fix is available for github.com/gravitl/netmaker — see the affected versions and patch details below.
Netmaker vulnerable to Insufficient Granularity of Access Control
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for CVE-2022-36110.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2022-36110 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

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

Detection & mitigation playbook
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
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-36110 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-36110. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-36110 in your dependencies?
O3 Security finds CVE-2022-36110 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
