  - When dispatching SASL frames to authenticate the peer, Proton will also dispatch AMQP frames if they claim
    to be SASL frames. This allows authentication bypass. However there will be no user name set so the
    effects depend on how the application deals with this condition - which otherwise means that
    authentication has not completed yet. This issue affects Apache Qpid Proton C: through 0.40.0. Users are
    recommended to upgrade to version 0.41.1, which fixes the issue. (CVE-2026-114230)
