CVE-2026-54551

WireGuard Portal, or wg-portal, is a web-based configuration portal for WireGuard server management. From 2.2.0 until 2.3.0, the authenticated GET /api/v0/ws statistics WebSocket in internal/app/api/v0/handlers/endpoint_websocket.go subscribes to TopicPeerStatsUpdated and TopicInterfaceStatsUpdated and forwards every TrafficDelta event without per-user authorization in handleWebsocket(). A low-privilege user can enumerate peer public keys through EntityId and monitor BytesReceived and BytesTransmitted values for peers belonging to other users. The same connection exposes interface_stats and interface names that the REST API limits to administrators. Tunnel content, AllowedIPs, and user identities remain authorization-gated. This issue is fixed in version 2.3.0.
