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

The Ultimate Member WordPress plugin before 2.6.7 does not prevent visitors from creating user accounts with arbitrary capabilities, effectively allowing attackers to create administrator accounts at will. This is actively being exploited in the wild.
