From 49eb4d4ddf61e25c5aaab89aa630ddd3c7f3c23d Mon Sep 17 00:00:00 2001 From: ThibG Date: Thu, 10 Dec 2020 06:27:26 +0100 Subject: Add honeypot fields and minimum fill-out time for sign-up form (#15276) * Add honeypot fields to limit non-specialized spam Add two honeypot fields: a fake website input and a fake password confirmation one. The label/placeholder/aria-label tells not to fill them, and they are hidden in CSS, so legitimate users should not fall into these. This should cut down on some non-Mastodon-specific spambots. * Require a 3 seconds delay before submitting the registration form * Fix tests * Move registration form time check to model validation * Give people a chance to clear the honeypot fields * Refactor honeypot translation strings Co-authored-by: Claire --- app/controllers/about_controller.rb | 5 ++++- app/controllers/auth/registrations_controller.rb | 11 +++++++---- app/controllers/concerns/registration_spam_concern.rb | 9 +++++++++ app/javascript/packs/public.js | 11 +++++++++++ app/javascript/styles/mastodon/forms.scss | 8 ++++++++ app/models/user.rb | 7 +++++++ app/validators/registration_form_time_validator.rb | 9 +++++++++ app/views/about/_registration.html.haml | 3 +++ app/views/auth/registrations/new.html.haml | 3 +++ app/views/shared/_error_messages.html.haml | 3 +++ config/locales/en.yml | 1 + config/locales/simple_form.en.yml | 1 + spec/controllers/auth/registrations_controller_spec.rb | 4 ++++ 13 files changed, 70 insertions(+), 5 deletions(-) create mode 100644 app/controllers/concerns/registration_spam_concern.rb create mode 100644 app/validators/registration_form_time_validator.rb diff --git a/app/controllers/about_controller.rb b/app/controllers/about_controller.rb index abd1ec0cb..dcad5d3b4 100644 --- a/app/controllers/about_controller.rb +++ b/app/controllers/about_controller.rb @@ -1,12 +1,15 @@ # frozen_string_literal: true class AboutController < ApplicationController + include RegistrationSpamConcern + layout 'public' before_action :require_open_federation!, only: [:show, :more] before_action :set_body_classes, only: :show before_action :set_instance_presenter - before_action :set_expires_in, only: [:show, :more, :terms] + before_action :set_expires_in, only: [:more, :terms] + before_action :set_registration_form_time, only: :show skip_before_action :require_functional!, only: [:more, :terms] diff --git a/app/controllers/auth/registrations_controller.rb b/app/controllers/auth/registrations_controller.rb index eb0924190..a3114ab25 100644 --- a/app/controllers/auth/registrations_controller.rb +++ b/app/controllers/auth/registrations_controller.rb @@ -2,6 +2,7 @@ class Auth::RegistrationsController < Devise::RegistrationsController include Devise::Controllers::Rememberable + include RegistrationSpamConcern layout :determine_layout @@ -13,6 +14,7 @@ class Auth::RegistrationsController < Devise::RegistrationsController before_action :set_body_classes, only: [:new, :create, :edit, :update] before_action :require_not_suspended!, only: [:update] before_action :set_cache_headers, only: [:edit, :update] + before_action :set_registration_form_time, only: :new skip_before_action :require_functional!, only: [:edit, :update] @@ -45,16 +47,17 @@ class Auth::RegistrationsController < Devise::RegistrationsController def build_resource(hash = nil) super(hash) - resource.locale = I18n.locale - resource.invite_code = params[:invite_code] if resource.invite_code.blank?
