Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Netmaker makes networks with WireGuard. Prior to version 0.15.1, Improper Authorization functions lead to non-privileged users running privileged API calls. If someone adds users to the Netmaker platform who do not have admin privileges, they can use their auth tokens to run admin-level functions via the API. This problem has been patched in v0.15.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Netmaker versions prior to 0.15.1 contain an improper authorization vulnerability where non-privileged (non-admin) users can use their authentication tokens to execute admin-level API functions. This allows regular users to bypass authorization checks and perform privileged operations they should not have access to.

MitigationUpgrade to Netmaker version 0.15.1 or later which patches the authorization bypass. Review audit logs to identify any unauthorized admin actions performed by non-privileged users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Netmaker version
    Query the Netmaker API endpoint /api/version or check the container image tag / binary version (e.g., docker ps, netmaker --version)
    Affected if The version is lower than 0.15.1 (e.g., 0.14.0, 0.13.0, etc.)
  2. Identify non-admin users
    Query the /api/users endpoint with admin credentials to list all users and their roles
    Affected if Any non-admin users exist in the system (users with role 'user' or similar non-privileged roles)
  3. Review audit logs for admin actions
    Examine Netmaker server logs or audit logs for API calls to /api/admin/* endpoints. Look for requests where the Authorization token belongs to a non-admin user
    Affected if Any admin API calls were made using non-admin user tokens (e.g., user creating other users, modifying network settings, accessing system config)
  4. Check API access logs for privilege escalation patterns
    Review server access logs for patterns such as non-admin users accessing endpoints like /api/networks, /api/nodes, or /api/users with elevated permissions
    Affected if Non-admin users have accessed endpoints that should require admin privileges

You are affected if your Netmaker version is below 0.15.1 AND you have non-admin users who may have performed or could perform admin-level operations.

Upgrade available Upgrade to 0.15.1 or later
Fixed in 0.15.1
Interim mitigation

Upgrade to Netmaker version 0.15.1 or later which patches the authorization bypass. Review audit logs to identify any unauthorized admin actions performed by non-privileged users.

Recommended fix High confidence

0.15.1

  1. Backup your current Netmaker configuration and data before upgrading
  2. Stop the Netmaker services
  3. Upgrade Netmaker to version 0.15.1 or later by following your installation method (Docker, binary, or from source)
  4. For Docker: pull the latest image and recreate containers
  5. For binary: download the new binary and replace the old one
  6. For source: pull the latest code and rebuild
  7. Verify the upgrade by checking the version number
  8. Ensure non-admin users can no longer access admin-level API endpoints
