The advisory
The OTP Login & Register Woocommerce WordPress plugin before 2.7.3 does not adequately limit one-time-password verification attempts, because the attempt limit is tracked against a value the client itself supplies and can change freely, allowing an unauthenticated attacker to bypass the limit and brute-force the short numeric login code to take over an account without its password.
