CVE-2026-73561: CWE-400: Uncontrolled Resource Consumption in anephenix hub
CVE-2026-73561 is an uncontrolled resource consumption vulnerability in anephenix hub, a Node.js WebSocket server and client. Versions prior to 0.2.16 improperly handle unauthenticated WebSocket connections by starting a polling loop that is never cleared if the client disconnects silently. This leads to unbounded timers and heap allocations, exhausting CPU and memory resources and causing server unavailability. The issue is fixed in version 0.2.16.
AI Analysis
Technical Summary
The vulnerability occurs because the hub server triggers loadDefaultConnectionEventListeners on every incoming unauthenticated WebSocket connection, which calls requestClientId. This function sends an RPC request and starts a setInterval polling loop every 10 milliseconds to wait for a reply. If the client disconnects without responding, the polling loop and pending request are not cleared, leading to resource exhaustion. Repeated exploitation can cause the server to become unavailable due to CPU and memory exhaustion. The flaw is resolved in version 0.2.16.
Potential Impact
Exploitation of this vulnerability results in high resource consumption on the server, specifically CPU and memory exhaustion, which can cause denial of service by making the server unavailable. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Upgrade to anephenix hub version 0.2.16 or later, where this issue is fixed. No other mitigation or workaround is indicated in the available data.
