CVE-2023-6394: Quarkus: graphql operations over websockets bypass
First published: Thu Nov 30 2023(Updated: )
A flaw was found in Quarkus. This issue occurs when receiving a request over websocket with no role-based permission specified on the GraphQL operation, Quarkus processes the request without authentication despite the endpoint being secured. This can allow an attacker to access information and functionality outside of normal granted API permissions.
