Description An issue in the WebSocket server used for Hot Module Replacement (HMR) allows attackers to steal a developer's source code because the origin of requests is not validated. This enables a remote attacker to receive HMR messages sent by the WebSocket server via a ws://127.0.0.1:8080/ connection from any origin.
