The legacy graphql-ws subprotocol handler fails to verify that a connection_init handshake has taken place before handling start messages.

The weakness corresponds to an authentication bypass scenario.", "risk_and_exploitability": "The CVSS score of 7.5 indicates a high severity for remote unauthenticated exploitation.
