Prior to 1.5.3 and 1.6.1, due to the peer verification logic in virt-handler (via verifyPeerCert), an attacker who compromises a virt-handler instance, could exploit these shared credentials to impersonate virt-api and execute privileged operations against other virt-handler instances potentially compromising the integrity and availability of the VM managed by it.
