CVE-2026-73561 Hub: Unauthenticated WebSocket RPC Waiter Resource Exhaustion

Hub is a Node.js WebSocket server and client with added features. Prior to 0.2.16, every incoming unauthenticated WebSocket connection triggers loadDefaultConnectionEventListeners to call requestClientId, which calls rpc.send for the get-client-id action and pushes a request into RPC.requests. Th...
