CVE-2026-45736 is an uninitialized-memory disclosure vulnerability in the ws WebSocket client and server library for Node.js. In versions earlier than 8.20.1, websocket.close() can disclose uninitialized memory when its reason argument is supplied as a TypedArray. The flaw results from unsafe handling of the TypedArray during close-frame processing, allowing unintended process memory contents to be included in data sent to a WebSocket peer.
