Upgrade Starscream to version 2.0.4 or higher.

Overview

Starscream is a conforming WebSocket (RFC 6455) client library in Swift.

Affected versions of this package are vulnerable to SSL Certificate Bypass. Allows an SSL Pinning bypass because of incorrect management of the certValidated variable (it can be set to true but cannot be set to false). If an attacker in a man-in-the-middle position is able to reset an established TCP connection between the client and server, the subsequent re-connection will not pin the SSL certificate, allowing traffic interception.
