An **incorrect authorization** flaw has been found in **network interface handling** in the **Foreman** package. The domain and subnet interface API checks only that the caller holds a host permission. It does not apply the search limit on that permission, so the request is answered from every interface on the domain or subnet. A low-privileged network attacker or user must already be allowed to view some hosts and to view a domain or subnet shared with other hosts. They can request that domain or subnet's interfaces. The response includes interface records of hosts they are not allowed to view. If the attacker or user is also allowed to edit some hosts, they can submit a change to one of those interfaces. The interface is then saved with that change.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
