From the auth /security-review (contained fixes; architectural SA3 proxy-trust +
SA4 session-revocation deferred to the user):
- SB1: encrypt the OAuth access_token at rest (was plaintext while refresh_token
was encrypted) — a ~1h Google bearer credential. New security.decrypt_optional()
falls back to a refresh for legacy plaintext tokens; column is unbounded String.
E2E-verified: token refreshed → stored as Fernet ciphertext → 319-subscription
YouTube sync succeeded.
- SA5: password_login is no longer a timing/enumeration oracle — it always runs
argon2 (against a decoy hash for unknown/passwordless emails), so response time
can't reveal whether an account exists.
- SB2: Google login only ADOPTS+activates a pre-existing password account when
Google actually attests email_verified (defense-in-depth against takeover); and
the email sync won't overwrite with a value another account owns (avoids a 500).
- demo_login clears the wallet first (demo can't switch to / act as a real account
via the multi-account header); switch_account rejects a suspended target (which
would otherwise clear the whole session on the next request).
Re-review clean; ruff clean; localdev boots; YouTube auth path E2E-verified.
- PlexBrowse.tsx: self-contained Plex mode (library scope tabs, own search +
sort, poster-card grid with watch state + playability tint, paged; show →
seasons/episodes drill-down). Playback announces (P2 wires the real player).
- Feed source dropdown gains a 'Plex' option (gated on me.plex_enabled); App
swaps <Feed> for <PlexBrowse> when librarySource==='plex' so the video-feed
hooks don't run in Plex mode. me exposes plex_enabled.
- api client (plexLibraries/plexBrowse/plexShow/plexImageUrl) + types; librarySource
union + share-URL restore gain 'plex'; new plex i18n namespace en/hu/de.
- Verified over HTTP (authed): libraries, browse+FTS, image proxy 200 image/jpeg.
The logged-out landing probed /api/me, which 401'd, and the browser logs every
non-2xx fetch as a console error regardless of how the app handles it. The
bootstrap probe now returns 200 with {authenticated:false} via a new
optional_current_user dependency; api.me() maps that to null. The render gate
treats no-data as 'signed out' -> the landing, and a thrown error as a real
network/5xx failure. Other protected endpoints still 401, so mid-session expiry
is still caught by the global handler. Lighthouse (dev): Best Practices 96->100.
- app/utils.py: shared valid_email() + now_utc() (one email regex, was duplicated
in auth.py and admin.py with a looser "@"-in check elsewhere).
- security.hash_token(): one SHA-256 token hasher (was duplicated in auth.py + state.py).
- auth.admin_user dependency + count_admins() helper, replacing the inline role
checks and the last-admin count query repeated across admin.py/me.py/tags.py.
- /api/me exposes instance-wide google_enabled. The onboarding nudge no longer auto-opens, and
Settings hides the YouTube-access section + the 'Connect Google' option, when the instance has
no Google OAuth configured (e.g. an email+password-only self-host). A linked account still shows
its 'Connected' status.
- Link a Google account to a password account, and adopt the Google identity onto a matching
email account instead of 500ing on a duplicate; set or change a password from Settings.
- Expose has_google/has_password on /api/me for the Sign-in methods UI.
- Mark Google logins email-verified (backfill existing rows, migration 0024); stop a routine
login from clobbering an admin-assigned role (env ADMIN_EMAILS stays the bootstrap admin).
- Suspension login-gates (password + Google callback + current_user) with a rate-limited
'suspended' notice; shared purge_user (cascade delete + access-request cleanup + Google-grant
revoke) behind self- and admin-deletion; single app_base source for user-facing email links.
Add DELETE /api/me/account: permanently erases the signed-in account and all its
personal data — OAuth tokens, subscriptions, tags, video states, playlists,
notifications all cascade on the users row (FK ON DELETE CASCADE); quota-audit
events are kept but anonymised (SET NULL); the email's invite/whitelist row is
removed too. Guards: the shared demo account can't be deleted, and the last
remaining admin can't delete itself. Frontend: a Danger zone in Settings -> Account
(non-demo) with a danger-confirm; on success the session clears and the app lands
on the welcome page. EN/HU/DE. Verified via curl: self-delete + session clear +
demo 403.
Whitelisted emails enter the shared demo user via /auth/demo (lazily
created, no OAuth token/scope), rate-limited per IP and answering
uniformly so it can't be hammered as an enumeration oracle. Add a
require_human dependency that blocks the demo account from quota-spending
sync endpoints and the OAuth upgrade flow, and surface is_demo on /api/me.
Track every account that completes OAuth in a browser session (session 'account_ids',
~14-day cookie), so the user can switch between them without another Google round-trip.
New GET /api/me/accounts (switchable accounts, active flagged) and POST /api/me/switch
(guarded: target must be in the session list — proof it signed in here — and re-checked
against is_allowed in case the invite was revoked). Logout now signs out the active
account and falls back to the most recent remaining one, else clears the session. UI: the
account popover lists the other signed-in accounts (click to switch, reloads) plus an
'Add another account' action (-> /auth/login, which uses prompt=select_account).
Trilingual. Third step of Epic N.
Base login now requests only openid/email/profile (non-sensitive), so a new user
gets a clean Google consent with no "unverified app" warning and no 7-day refresh
token expiry. YouTube read (youtube.readonly) and write (youtube) are granted later
by the onboarding wizard via a parameterized /auth/upgrade?access=read|write.
Security fixes folded in from the baseline audit:
- config: refuse to boot in production (https OAUTH_REDIRECT_URL) with the
placeholder/short SECRET_KEY or a missing TOKEN_ENCRYPTION_KEY, closing a
session-forgery / admin-impersonation hole.
- main: mark the session cookie Secure when served over HTTPS.
- me: expose can_read; sync/subscriptions returns a friendly 403 (not a 500)
until YouTube read access is granted.
Move the access whitelist from the ALLOWED_EMAILS env var into a DB Invite table
(env kept as bootstrap fallback), and add a self-service request + admin approval
flow with fail-soft email.
- models: Invite(email, status pending|approved|denied, requested_at, decided_*)
- migration 0008: invites table; seed env ALLOWED_EMAILS u ADMIN_EMAILS as approved
- auth: is_allowed() (DB-first, env fallback); a denied Google login records a pending
request and bounces to /?access=requested instead of a raw 403; public POST
/auth/request-access; upsert is idempotent so repeats don't re-spam admins
- routes/admin.py (admin-only): list/approve/deny invites + manual add
- email.py: smtplib + Gmail App Password, fail-soft (skips if SMTP unset)
- /api/me exposes pending_invites; config + .env.example gain SMTP_*
- UI: Login 'Request access' form + access=requested/denied handling; Settings ->
Access requests (approve/deny + add); admin nudge toast on pending requests
Verified locally: request-access creates a pending invite and emails the admin;
seed approved npeter83; guinea-pig yt.trash2023 denied until approved.
