Update Devise to 4.7.1
Devise Gem for Ruby confirmation token validation with a blank string
Devise before 4.7.1 confirms accounts upon receiving a request with a blank confirmation_token, if a database record has a blank value in the confirmation_token column.
However, there is no scenario within Devise itself in which such database records would exist.
Patched versions: >= 4.7.1
Unaffected versions: none
