Authora - Easy Login with Mobile Number < 1.7.7 - Unauthenticated Account Takeover via OTP Disclosure

The Authora : Easy login with mobile number WordPress plugin before 1.7.7 does not keep its one-time login code confidential, returning the code and a valid verification token in the response of an unauthenticated action, allowing unauthenticated attackers to log in as any user whose registered mobile number they know (including administrators) or to create arbitrary accounts.
