Netmaker Access Control and Authorization Issues

Netmaker versions prior to 1.5.0 fail to properly validate role assignments in the user update API endpoint, allowing authenticated admin users to escalate their privileges to super-admin. An attacker with admin credentials can exploit this authorization bypass to gain unrestricted access to the platform. No patch is currently available for affected installations.

Netmaker versions prior to 1.5.0 expose WireGuard private keys through unauthenticated API endpoints when accessed by users with the platform-user role, allowing credential theft across all network configurations despite UI-level access restrictions. An authenticated attacker can retrieve sensitive cryptographic material by directly calling GET /api/extclients/{network} or GET /api/nodes/{network} endpoints that lack proper output filtering. This vulnerability affects Netmaker and its integrated WireGuard deployments, with no patch currently available for affected versions.
