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

The Login & Register Forms WordPress plugin before 4.0.2 does not enforce its password reset attempt limit against a server-derived value, keying both the verification code and the per-source attempt counter on client-controlled data, allowing unauthenticated attackers to reset the limit at will and brute-force the code to take over any account, including administrators, when the verification-code reset mode is enabled.
