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
