Overview

Affected versions of this package are vulnerable to Uncaught Exception in handling error events. If there is no listener set up for such events, an attacker can send packets containing them to crash the Node process.

This vulnerability can be avoided by attaching a listener for error events, such as
io.on("connection", (socket) => {
socket.on("error", () => {
// ...
});
});
