NVD Description

Note: Versions mentioned in the description apply only to the upstream openstack-neutron-openvswitch package and not the openstack-neutron-openvswitch package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In OpenStack Neutron before 28.0.2, the subnetpool onboarding API does not verify ownership of the target subnets. An authenticated user can onboard subnets from another project's shared network into their own subnetpool, mutating the victim's subnet state and altering L3 routing and address scope behavior for victim routers.
