feat(auth): mPass SSO via oauth2-proxy ForwardAuth#2
Merged
Conversation
Backend: - ProxyAuthMiddleware reads X-Auth-Request-Email on every request - JIT-provisions Plane user on first login (get_or_create + Profile) - Calls user_login() to establish native Django session - Bypasses god-mode and /api/instances paths (local admin auth still works) - Unit tests for all middleware scenarios Frontend (plane-web): - 3-layer logout: Plane session → /oauth2/sign_out → Cognito logout - Extract oauth2-proxy URL helpers (core/lib/oauth2-proxy.ts) - Harden authentication-wrapper redirect logic - Dockerfile.web: add VITE_OAUTH2_PROXY_BASE_PATH, VITE_OIDC_LOGOUT_URL, VITE_OIDC_CLIENT_ID build args - CI: GHCR build workflow for SSO branch
… redirect, add middleware order tests - Remove debug print() and unused sys import from ProxyAuthMiddleware - Update security note to clarify that unexposed backend port prevents header spoofing - Fix api.service.ts 401 redirect to pass full window.location.href as rd param (was passing path-only which oauth2-proxy cannot redirect back from) - Gate oauth2 sign-in redirects in authentication-wrapper on VITE_OAUTH2_PROXY_BASE_PATH so native Plane login remains reachable when SSO is not configured - Add TestProxyAuthMiddlewareSettings: guards middleware registration and enforces that ProxyAuthMiddleware comes after AuthenticationMiddleware in the stack
_coerce_bypass_paths was wrapping a raw comma-separated string like "/god-mode,/api/instances" into a single-element list instead of splitting it. Now splits on commas and strips whitespace, matching the behaviour of the env var path in settings/common.py. Falls back to defaults if the result is empty (e.g. input is ",,,"). Added tests for comma-separated, spaced, and empty-comma inputs.
Plane's signout previously only cleared the Django session, leaving the shared oauth2-proxy session alive — Traefik ForwardAuth would immediately re-authenticate the user on the next request. - Redirect to MPASS_SIGNOUT_URL (oauth2-proxy /sign_out?rd=Cognito logout) when the setting is configured, clearing both layers in one redirect. - Fall back to base_host redirect for non-SSO deployments (original behaviour). - Add 4 unit tests covering MPASS_SIGNOUT_URL set/unset and DB exception paths.
The frontend signOut() previously POSTed a CSRF form to /auth/sign-out/, which is no longer wired in the SSO flow — the request would fail and leave the oauth2-proxy session intact, silently re-authenticating the user on the next page load. mPass is now the sole identity provider, so signOut() redirects directly to buildOAuth2SignOutUrl(window.location.origin). The user store (core/store/user/index.ts) already builds the Cognito logout rd= target on top of this for full 3-layer logout (app session → oauth2-proxy cookie → Cognito session).
Comment out all native OAuth (Google/GitHub/GitLab/Gitea), email/password, and magic link URL patterns. oauth2-proxy ForwardAuth is the sole login method. Sign-out and CSRF token endpoints kept active. Routes are commented (not deleted) so they can be restored if mPass is removed. god-mode (/god-mode/*) bypasses ForwardAuth and uses Plane's local admin login independently.
Build and push plane-backend SSO image manually instead of via CI.

Pull request overview
Adds mPass SSO integration by trusting oauth2-proxy ForwardAuth headers on the backend to establish Django sessions, and updates the Plane web app to redirect unauthenticated users through oauth2-proxy with an SSO-aware logout flow. This aligns Plane auth to a single external IdP while preserving local “god-mode” access.
Changes:
- Backend: introduce
ProxyAuthMiddleware(email header → JIT user provision → Django session) plus bypass-path support and tests. - Frontend: add oauth2-proxy URL helpers, redirect unauthenticated flows to
/oauth2/sign_in, and implement 3-layer logout plumbing. - Disable native auth routes (OAuth providers, email/password, magic links) in the API routing layer and document the intended behavior.

AuthService.signOut now performs a client-side redirect to oauth2-proxy and no longer clears the Django session (POST /auth/sign-out/). This breaks the intended 3-layer logout flow (and makes the "_baseUrl" parameter unused) and can leave Plane sessions valid so a user is effectively still logged in after re-auth. Consider restoring signOut() to call the backend sign-out endpoint (or otherwise invalidate the Django session) and keep the oauth2-proxy/Cognito redirect in one place (e.g., the caller or the backend redirect).

UserStore.signOut triggers navigation via authService.signOut() and then also unconditionally sets window.location.href again in finally. With the current AuthService implementation this can cause competing redirects and may prevent resetOnSignOut()/OIDC logout from running reliably. Recommend making only one layer responsible for browser navigation (either AuthService or UserStore) and ensuring the Django-session invalidation step happens before the final redirect.

logout(request) is only called inside the try-block; if User lookup/save fails, the exception is swallowed and the Django session is not cleared. If the intent is to always sign the user out even when updating audit fields fails, call logout(request) in a finally block (or in the except) so session invalidation is guaranteed.

There was a problem hiding this comment.
MPASS_BYPASS_PATHS env parsing doesn’t strip whitespace (and will keep whitespace-only segments), but the helper tests/support code expect comma-separated values to be trimmed. This can make values like "/god-mode, /api/instances" fail to match. Suggest using p.strip() (and filtering on the stripped value), or store the raw string in settings and let _coerce_bypass_paths handle splitting/stripping consistently.

This test’s docstring/spec says the Django session is cleared even when user.save() raises, but the test never asserts that logout() was called in this scenario. Adding an assertion on the patched logout() would make the test actually enforce the intended behavior (and would catch regressions like logout being skipped on exceptions).

| ### 9. API response returns 401 | ||
|
|
||
| ``` | ||
| GIVEN any API call returns HTTP 401 | ||
| WHEN the Axios response interceptor fires | ||
| THEN window.location.replace is called with: | ||
| <origin> + buildOAuth2SignInUrl(<path + search>) | ||
| i.e. http://localhost/oauth2/sign_in?rd=%2Fissues%2F%3Ffilter%3Dopen | ||
| AND the user is redirected to re-authenticate | ||
| ``` | ||
|
|
||
| ### 10. 401 rd parameter carries path only (not full origin) | ||
|
|
||
| ``` | ||
| GIVEN current page is http://localhost/issues/?filter=open | ||
| AND an API call returns 401 | ||
| WHEN the interceptor fires | ||
| THEN rd equals encodeURIComponent("/issues/?filter=open") | ||
| (path + search only — origin is prepended separately outside the helper) | ||
| ``` |
There was a problem hiding this comment.
The spec for the 401 interceptor describes passing only path+search as the rd value and prepending origin separately, but the current implementation uses buildOAuth2SignInUrl(window.location.href) (full URL). Update the spec (cases 9–10) to match the implemented behavior, or adjust the interceptor to use path+search if that’s the intended contract.

| AND VITE_OIDC_CLIENT_ID is set | ||

||
| ``` | ||
| GIVEN VITE_OIDC_LOGOUT_URL is not set (or VITE_OIDC_CLIENT_ID is not set) | ||

||
| ``` | ||
| GIVEN POST /auth/sign-out/ throws a network error or returns an error status | ||
| WHEN signOut() is called | ||
| THEN the error is caught and swallowed | ||
| AND resetOnSignOut() is still called | ||
| AND the /oauth2/sign_out redirect still happens | ||

The logout spec says signOut() first POSTs /auth/sign-out/ to clear the Django session, then redirects via oauth2-proxy; however the current frontend AuthService.signOut() performs only a client-side redirect and does not call the backend endpoint. Align this spec section (cases 11–14) with the actual code path, or adjust the implementation to match the documented 3-layer sequence.
…+ harden logout - signOut() now POSTs to /auth/sign-out/ (Django session cleared) instead of navigating directly; UserStore owns the redirect (no competing navigations) - logout(request) moved to finally block so Django session is always cleared even if user.save() raises - MPASS_BYPASS_PATHS parsing strips whitespace to avoid silent match failures - Test asserts logout() is called when save() raises - Document MPASS_SIGNOUT_URL in .env.example
The logout flow's logout_uri was set to window.location.origin (https://foss-pm.local.moneta.dev) which is behind ForwardAuth. After Cognito cleared the session, the user would bounce back to Cognito login instead of seeing the landing page. Changes: - store/user/index.ts: read VITE_LOGOUT_REDIRECT_URL instead of window.location.origin for the Cognito logout_uri parameter. Falls back to origin for non-devstack deployments. - Dockerfile.web: add ARG + ENV for VITE_LOGOUT_REDIRECT_URL so Vite can bake it into the JS bundle at build time.
Upstream Plane gates PR lint/CodeQL/Codespell on preview/canary/master; none of those exist on the Pressingly fork, so fork PRs ran nothing. Retarget the five PR-driven workflows to foss-main so fork PRs exercise build, lint, CodeQL, and codespell. Copyright check runs addlicense against COPYRIGHT.txt — fork commits don't carry that header and the check would false-fail every PR. Reduced to workflow_dispatch only (kept on disk so upstream merges don't silently re-enable it).

When oauth2-proxy forwards a bare username in X-Auth-Request-Email
(e.g. user_id_claim=cognito:username), synthesize {username}@{SMB_NAME}.com
so Plane can create/find a user. Falls back to X-Auth-Request-User if the
email header is empty.
Needed for Cognito pools where users have no email attribute (moneta-style),
only a numeric or alphanumeric username in cognito:username.
Instead of generating a random UUID hex, derive the Plane username from the email local part (text before @). Falls back to uuid4().hex when the derived value collides with an existing account's username. Makes Plane usernames human-readable and predictable — matches the SSO identity (e.g. cognito:username) visible in upstream systems.
Single-tenant SSO has unique email local parts by construction, so the fallback UUID path is dead weight. Let IntegrityError surface — easier to observe and alert on than a silent retry.

All four comments from the PR #32 review are valid. Fixes: #1 (sso-audit.sh:29) — Row 14 description claimed three checks (no /oauth2/sign_out, portal-host redirect, no POST /auth/sign-out/) but the function only verifies the first. Narrows the comment to match what's actually implemented. The other two properties from logout-flow spec need runtime context or AST analysis; not in scope for this deterministic gate. #2 (sso-auth.sh:131) — Row 20 detection was brittle: - Single-line regex missed parenthesized multiline imports (`from django.contrib.auth import (\n login,\n logout,\n)`) - Call regex required exact `logout(request)` — missed whitespace (`logout( request )`), keyword form (`logout(request=request)`), and aliased call sites (`auth_logout(request)`) Could false-fail on legitimate fixes → block merges spuriously. New detection uses Python's `ast` module to parse the proxy_auth.py import block and extract the in-scope name for django.contrib.auth.logout (alias or plain). Then a whitespace-tolerant grep checks for a call to that name. Handles every variant in one pass without writing multi-line regex in bash. Verified against a synthetic fixture with aliased + parenthesized + whitespaced call. #3 (sso-audit.sh:191) — Output referenced `skills/app-rules/SKILL.md`, which lives in awais786/sso-rules-moneta, not in Pressingly/plane. Confused readers of the sticky PR comment. Replaced both repo- relative references with full GitHub URLs so the links work from the PR view. #4 (.github/workflows/sso-audit.yml:62) — `marocchino/sticky-pull- request-comment@v2` needs `pull-requests: write`. PRs from external forks get a read-only GITHUB_TOKEN regardless of declared permissions, and the action errors out, marking the whole workflow failed even when the audit passed. Two-layer fix: - Skip the comment step on fork PRs via `github.event.pull_request.head.repo.full_name == github.repository` - Add `continue-on-error: true` as a defensive belt so other comment-posting failures (rate limit, GitHub API blip) don't fail the audit gate either The audit gate itself (final exit-1 step) is unaffected — still blocks merge on security-critical violations regardless of comment posting. Local dry-run on foss-main still produces the expected red ❌ on row 20 with the new alias-aware detection. Switching to the fix branch detects the import (as `logout`) and the call site correctly.
