    Vendor assessment for this product only.

    pkg:rpm/redhat/openstack-ironic-api

    • workaround: There is no complete mitigation without the upstream patch. To reduce risk before an errata is available: 1. Keep the baremetal:node:vendor_passthru policy at the default system administrator requirement; do not grant vendor passthrough to project-scoped roles. 2. Restrict network access to the OpenStack Bare Metal (Ironic) API to trusted management networks. 3. Avoid delete_subscription and get_subscription vendor passthrough calls with untrusted subscription ids until a fixed package is installed.
