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

The Temporary Login Without Password WordPress plugin before 1.9.9 does not verify that the user requesting a temporary login holds network super admin rights before granting the new account those rights, allowing an administrator of a single site on a multisite network to take over the whole network. The same missing check also allows an existing account, including the attacker's own, to be promoted.
