Official description
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.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Selection of Less-Secure Algorithm During Negotiation
A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used in a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.
