Temporary Login Without Password vulnerability

What happened

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.

Affected versions

Temporary Login Without Password: 1.5 through before 1.9.9 (semver) Fixed: See vendor advisory.
