  - An authorization flaw was found in openstack-barbican. The default policy rules for the secret metadata
    API allowed any authenticated user to add, modify, or delete metadata from any secret regardless of
    ownership. This flaw allows an attacker on the network to modify or delete protected data, causing a
    denial of service by consuming protected resources. (CVE-2022-23451)

  - An authorization flaw was found in openstack-barbican, where anyone with an admin role could add secrets
    to a different project container. This flaw allows an attacker on the network to consume protected
    resources and cause a denial of service. (CVE-2022-23452)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
