PreMiD 2.2.0 allows unintended access via the websocket transport. An attacker can receive events from a socket and emit events to a socket, potentially interfering with a victim's "now playing" status on Discord.

managers/socketManager.ts in PreMiD through 2.1.3 has a locally hosted socketio web server (port 3020) open to all origins, which allows attackers to obtain sensitive Discord user information.
