Is this vulnerability remotely exploitable?

Yes. If the GraphQL WebSocket subscription endpoint is exposed over the internet or another untrusted network, an attacker can remotely connect and execute operations without valid credentials.

Does exploitation require prior authentication or valid API keys?

No. The core issue is that the WebSocket endpoint does not enforce the usual authentication middleware, so a client can interact with GraphQL operations without a valid application key or API key.

What is the safest general fix pattern?

The safest approach is to ensure that all GraphQL transports (HTTP and WebSocket) share a unified security pipeline: the same authentication, authorization, introspection controls, and query complexity limits should be applied consistently, ideally via centralized middleware or execution hooks.
