Description
WordPress 4.5 introduced the ability to login with an email address instead of a username. Google Authenticator v0.47 wasn't aware of the new feature, and didn't properly handle the case where an email address was used instead of a username. Using an email address would allow an attacker with a valid password to bypass the two-factor OTP.

Affects

Plugin google-authenticator
fixed in version 0.48
