Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Quarkus io.quarkus:quarkus-smallrye-graphql-client versions from 2.14.0 before 3.5.3, and versions before 2.13.9.Final, are affected. When a GraphQL operation has no role-based permission set and the request arrives over a websocket, the request is processed without authentication even though the endpoint is secured, so an attacker can reach information and functionality beyond their granted API permissions. Upgrade to version 3.5.3 or 2.13.9.Final.
