Description

omniauth-apple is the OmniAuth strategy for "Sign In with Apple" (RubyGem omniauth-apple). In omniauth-apple before version 1.0.1 attackers can fake their email address during authentication. This vulnerability impacts applications using the omniauth-apple strategy of OmniAuth and using the info.email field of OmniAuth's Auth Hash Schema for any kind of identification. The value of this field may be set to any value of the attacker's choice including email addresses of other users. Applications not using info.email for identification but are instead using the uid field are not impacted in the same manner. Note, these applications may still be negatively affected if the value of info.email is being used for other purposes. Applications using affected versions of omniauth-apple are advised to upgrade to omniauth-apple version 1.0.1 or later.
