## What is CVE-2026-29195?

CVE-2026-29195 is a medium-severity vulnerability in gravitl netmaker, published on 7 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official 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.

Weakness: CWE-863 (Incorrect Authorization)
