Ubuntu

A vulnerability was found in quarkus-core. This vulnerability occurs because the TLS protocol configured with quarkus.http.ssl.protocols is not enforced, and the client can force the selection of the weaker supported TLS protocol.

Weakness

A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.
