No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability in the API of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to obtain limited system information and to change the state of certain settings of a vulnerable system. Successful exploitation could allow an attacker to gain insight into internal services and workflows and to make unauthorized changes that may disrupt the normal operation of the affected service.
