CVE-2026-73561: CWE-400: Uncontrolled Resource Consumption in anephenix hub
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. The RPC.waitForReply function starts a setInterval polling loop every 10 milliseconds that is cleared only after a matching reply; if the client remains silent and closes, the timer and pending request stay allocated because the socket close path does not cancel them. Repeated connections therefore cause unbounded timers and heap entries, exhausting CPU and memory and making the server unavailable. This issue is fixed in version 0.2.16.
AI Analysis
Technical Summary
The vulnerability arises because every incoming unauthenticated WebSocket connection triggers a process that starts a setInterval polling loop every 10 milliseconds, which is only cleared after receiving a matching reply. If the client remains silent and closes the connection, the timer and pending request are not canceled, causing unbounded accumulation of timers and heap entries. Repeated connections exploit this flaw to exhaust server CPU and memory resources, resulting in denial of service. The flaw is resolved in anephenix hub version 0.2.16.
Potential Impact
Exploitation leads to uncontrolled resource consumption (CPU and memory exhaustion) on the server, making the anephenix hub unavailable. There is no impact on confidentiality or integrity reported. The vulnerability can be triggered remotely without authentication.
Mitigation Recommendations
Upgrade to anephenix hub version 0.2.16 or later, where this issue is fixed. No other mitigation or workaround is indicated.
