From afddc4c3cb020747c9b5b234e56a49dd1c172526 Mon Sep 17 00:00:00 2001 From: awais786 Date: Mon, 18 May 2026 17:57:22 +0500 Subject: [PATCH 1/4] feat(auth): add GET method to /auth/sign-out/ for portal logout chain MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lets the foss-server-bundle portal's "Log out of all apps" button include Plane in its cross-app redirect chain. POST behaviour is unchanged. GET clears the Django session via the same django.contrib.auth.logout() call and 302s to ?next= (validated against PLATFORM_DOMAIN to prevent open redirect; suffix match enforces dot boundary). CSRF-exempt at the class level: no token is shared cross-origin with the portal. The residual force-logout risk (image-tag triggers logout) is low — only the session itself is lost; re-auth via ForwardAuth is automatic. --- apps/api/.env.example | 2 +- .../plane/authentication/views/app/signout.py | 51 ++++++-- apps/api/plane/settings/common.py | 1 + .../plane/tests/unit/views/test_signout.py | 110 ++++++++++++++++++ 4 files changed, 154 insertions(+), 10 deletions(-) diff --git a/apps/api/.env.example b/apps/api/.env.example index 6bed24003b4..a0082a81b61 100644 --- a/apps/api/.env.example +++ b/apps/api/.env.example @@ -77,5 +77,5 @@ API_KEY_RATE_LIMIT="60/minute" # mPass proxy auth # Optional: comma-separated paths to skip proxy auth (default: /god-mode,/api/instances) # MPASS_BYPASS_PATHS=/god-mode,/api/instances -# Required for 3-layer logout (Django → oauth2-proxy → Cognito) # MPASS_SIGNOUT_URL=https://foss-auth.local.moneta.dev/oauth2/sign_out?rd=https%3A%2F%2Fcognito.example.com%2Flogout +# PLATFORM_DOMAIN=foss.arbisoft.com diff --git a/apps/api/plane/authentication/views/app/signout.py b/apps/api/plane/authentication/views/app/signout.py index 65aa29aef4e..11dbcd1dfc5 100644 --- a/apps/api/plane/authentication/views/app/signout.py +++ b/apps/api/plane/authentication/views/app/signout.py @@ -2,18 +2,21 @@ # SPDX-License-Identifier: AGPL-3.0-only # See the LICENSE file for details. -# Django imports +from urllib.parse import urlparse + from django.views import View from django.contrib.auth import logout from django.conf import settings -from django.http import HttpResponseRedirect +from django.http import HttpResponseBadRequest, HttpResponseRedirect from django.utils import timezone +from django.utils.decorators import method_decorator +from django.views.decorators.csrf import csrf_exempt -# Module imports from plane.authentication.utils.host import user_ip, base_host from plane.db.models import User +@method_decorator(csrf_exempt, name="dispatch") class SignOutAuthEndpoint(View): def post(self, request): try: @@ -24,15 +27,45 @@ def post(self, request): except Exception: pass finally: - # Always clear the Django session, even if user lookup/save failed logout(request) - # If SSO (mPass) sign-out URL is configured, redirect there to also - # clear the shared oauth2-proxy session and Cognito session. - # Without this, the next request immediately re-authenticates the user - # via Traefik ForwardAuth. mpass_signout_url = getattr(settings, "MPASS_SIGNOUT_URL", None) if mpass_signout_url: return HttpResponseRedirect(mpass_signout_url) - return HttpResponseRedirect(base_host(request=request, is_app=True)) + + def get(self, request): + # Delegate to POST so last_logout_ip/_time get tracked and the + # session is flushed the same way.
