From bddd9ba36d9f4e86e2a4bbea77f967c143afa2cc Mon Sep 17 00:00:00 2001 From: Claire Date: Sun, 23 Jan 2022 15:52:58 +0100 Subject: Add OMNIAUTH_ONLY environment variable to enforce externa log-in (#17288) * Remove support for OAUTH_REDIRECT_AT_SIGN_IN Fixes #15959 Introduced in #6540, OAUTH_REDIRECT_AT_SIGN_IN allowed skipping the log-in form to instead redirect to the external OmniAuth login provider. However, it did not prevent the log-in form on /about introduced by #10232 from appearing, and completely broke with the introduction of #15228. As I restoring that previous log-in flow without introducing a security vulnerability may require extensive care and knowledge of how OmniAuth works, this commit removes support for OAUTH_REDIRECT_AT_SIGN_IN instead for the time being. * Add OMNIAUTH_ONLY environment variable to enforce external log-in only * Disable user registration when OMNIAUTH_ONLY is set to true * Replace log-in links When OMNIAUTH_ONLY is set with exactly one OmniAuth provider --- app/controllers/api/v1/accounts_controller.rb | 6 ++++- app/controllers/auth/registrations_controller.rb | 6 ++++- app/helpers/application_helper.rb | 26 ++++++++++++++++++++- app/views/about/_login.html.haml | 29 ++++++++++++++++-------- app/views/auth/sessions/new.html.haml | 25 ++++++++++---------- app/views/auth/shared/_links.html.haml | 2 +- app/views/layouts/public.html.haml | 2 +- app/views/statuses/_status.html.haml | 2 +- 8 files changed, 70 insertions(+), 28 deletions(-) (limited to 'app') diff --git a/app/controllers/api/v1/accounts_controller.rb b/app/controllers/api/v1/accounts_controller.rb index cbccd64f3..5c47158e0 100644 --- a/app/controllers/api/v1/accounts_controller.rb +++ b/app/controllers/api/v1/accounts_controller.rb @@ -83,10 +83,14 @@ class Api::V1::AccountsController < Api::BaseController end def check_enabled_registrations - forbidden if single_user_mode? || !allowed_registrations? + forbidden if single_user_mode? || omniauth_only? || !allowed_registrations? end def allowed_registrations?
