AnalysisAIv1 – Mar 12, 2026

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.

Classified as CWE-863 (Incorrect Authorization). Affects Netmaker. Netmaker makes networks with WireGuard. Prior to version 1.5.0, a user assigned the platform-user role can retrieve WireGuard private keys of all wireguard configs in a network by calling GET /api/extclients/{network} or GET /api/nodes/{network}. While the Netmaker UI restricts visibility, the API endpoints return full records, including private keys, without filtering based on the requesting user's ownership. This issue has been patched in version 1.5.0.
