Five low-risk, high-value fixes surfaced by the security review:
#3 Branding lockdown — `custom_domain`/`custom_css` (which feed the PUBLIC,
pre-auth branding resolver and the login-page <style>) are now settable only
by platform admins; a workspace_admin can no longer hijack the platform login
page by claiming its domain. The public /api/branding (+ /domain) now return
only presentational fields via publicBranding() (no id/user_id/workspace_id/
custom_domain/timestamps leak).
#6 Strip device_token — the device WS auth secret (validated with
timingSafeEqual) was returned in device list/get/update + pairing responses
(SELECT d.* / *). New lib/device-sanitize.js strips it everywhere; prevents
device impersonation by any workspace user.
#7 must_change_password enforced server-side — was a frontend-only redirect, so
a provisioned temp password worked indefinitely via the API. requireAuth now
403s every route except GET/PUT /api/auth/me (the password change, which
clears the flag) and logout while the flag is set.
#8 XSS — escape user data interpolated into innerHTML in teams.js, kiosk.js,
layout-editor.js (team/page/layout/zone names, member name/email, kiosk
config fields). scriptSrcAttr 'unsafe-inline' made these exploitable via
injected event handlers, not just markup.
#9 Thumbnail IDOR — /api/content/:id/thumbnail had no auth/scope gate (any UUID
served any tenant's thumbnail). Now mirrors the /file route's playlist/widget
workspace-scoped reference check.
Tests: new test/security-fixes.test.js (device strip, publicBranding field
allowlist, must_change_password gate). Full suite 41/41. Verified live against a
prod-data copy: device_token absent from /api/devices, /api/branding trimmed.
Not addressed here (tracked for follow-up): Android OTA signature verification
(Critical), public widget-render XSS, token revocation/logout, pairing-code
strength, validateRemoteUrl hardening, import quota.

White-label is stored per-workspace (white_labels.workspace_id); unbranded and
new workspaces - and the login page - fell back to hardcoded ScreenTinker. Add a
single platform default that everything inherits beneath the per-workspace layer.
Resolution (lib/branding.js): workspace row -> custom-domain match -> platform
default -> hardcoded ScreenTinker. Row-level override: a workspace with its own
row keeps it (current behavior); only row-less workspaces inherit the default,
so editing the default propagates instantly (no row-copying at creation).
The platform default is a white_labels row with a FIXED id ('platform-default'),
not a "workspace_id IS NULL" sentinel - legacy pre-multitenancy rows can also
have a null workspace_id, which would be ambiguous.
- routes/admin.js: GET/PUT /api/admin/branding (requirePlatformAdmin) to read/
upsert the single platform-default row; audit-logged.
- server.js: public GET /api/branding (domain match -> platform default ->
hardcoded) for pre-login/pre-workspace contexts.
- routes/white-label.js: authed GET now falls back to the platform default
(was hardcoded) for row-less workspaces.
- Frontend: login page resolves + applies branding (logo, name, colors, favicon,
custom CSS) pre-auth; Admin page gets a "Default branding" form.
Tests: resolver order incl. legacy null-ws safety; admin GET/PUT (single row,
upsert, platform-admin-only 403). Full suite 37/37. Verified end-to-end:
public + authed + login-page all inherit the platform default; per-workspace
override preserved.
Closes#15.
Adds POST /api/admin/users so an admin can create a user directly with a
known password and assign them to a workspace + role - for self-hosted
instances with no outbound email, where invites never deliver.
Server (routes/admin.js, mounted /api/admin with requireAuth + activityLogger):
- Gated by canAdminWorkspace(db, req.user, targetWorkspace): 404 if the
workspace is missing, 403 if not an admin of it. This scopes org_admins
to their own org and excludes platform_operator (no user/role mgmt, #13).
- Validates email (invite-create regex), role in WORKSPACE_ROLES, password
min-8 (the /me rule). 409 on duplicate email - never overwrites.
- One transaction: global users row (auth_provider 'local',
bcrypt.hashSync(pw,10), must_change_password from the flag) + a
workspace_members row written inline (same footprint as an accepted
invite; accept-invite left untouched).
- Explicit audit row admin_create_user; never logs the password; response
excludes password/hash.
- HOSTED_INSTANCE: never calls sendSignupEmails and stamps both
welcome_email_sent_at / activation_nudge_sent_at, so an admin-created
user gets no welcome email and never enters the activation-nudge sweep.
must_change_password (frontend-first enforcement, per spec):
- Migration adds users.must_change_password INTEGER NOT NULL DEFAULT 0;
surfaced via requireAuth + /me + login responses.
- route() in app.js forces users with the flag to a #/change-password
screen (new force-password-change view, reuses PUT /api/auth/me) and
blocks every other view until set. The /me update clears the flag.
Frontend: "Add User" button beside "Invite member" in the members view
(admin-only) opening a modal (email, name, password + generate, role,
must-change checkbox); invite and Add User coexist. api.adminCreateUser;
EN i18n only.

Daily sweep (15:00 UTC) emails a warm, personal "checking in" message
to users who signed up 3-14 days ago and still have no paired screen,
nudging them toward activation. Once per user, reuses the Graph
transport (services/email.js) via the existing fromName/rawSubject
options.
- New service services/activationNudge.js, started from server.js.
Self-correcting daily scheduler (recompute next 15:00 UTC each run;
no node-cron dependency).
- Eligibility (Option B, workspace-aware): created 3-14 days ago,
activation_nudge_sent_at IS NULL, COALESCE(email_alerts,1)=1 (only
an explicit opt-out of 0 is excluded; NULL/unset still qualify), and
ZERO devices owned by the user OR present in any workspace they
belong to. The workspace check avoids nudging engaged team members.
- Idempotency: activation_nudge_sent_at, stamped after send; paired
sentinel-1 backfill so the first sweep can't blast the dormant
legacy base. Only genuinely-new signups become eligible.
- GATE: HOSTED_INSTANCE=true (positive hosted signal, NOT !selfHosted).
A daily bulk sweep would be far worse to leak than a single email, so
a self-hoster who configured Graph but missed SELF_HOSTED won't blast
their user base. Unset -> neither scheduled nor sent. Documented in
.env.example.
Smart TVs (Tizen, WebOS, Fire TV, Bravia) have no accessible browser
devtools, so when the player misbehaves on those platforms we previously
had zero visibility. This adds two paths to fix that:
- Visible debug overlay rendered on the TV screen for phone-photo capture
- Automatic server-side telemetry sink for hands-off error reporting
Client side (server/player/):
- Inline ES5 error trap as first script in index.html captures errors
even from parse-time failures in later scripts. Captures into
window.__debugLog with 200-entry cap.
- debug-overlay.js renders a fixed-position overlay covering the top 40%
of the screen. Activates via ?debug=1, d-e-b-u-g key sequence, Samsung
red button (keyCode 403), or smart-TV UA + ?autodebug=1. Freeze toggle
(F key or Samsung green) with visible FROZEN badge for phone capture.
pointer-events: none so touches pass through to the player underneath.
- Reporter machinery posts captured errors to /api/player-debug with
5-second debounce batching, sendBeacon on unload (with payload size
capping to stay under 64KB), 5-minute backoff after 429 responses.
UA-gated: smart-TV allow-list first (handles Tizen-with-Chrome/108),
modern-desktop deny-list second, default-report for unknown UAs.
- Two-pass djb2 fingerprint (16 hex chars) per error for future grouping.
- Absolute script src (/player/debug-overlay.js) so the script loads
regardless of trailing-slash on the player URL.
Server side:
- New player_debug_logs table (10000-row FIFO cap, indexed on
fingerprint + created_at). Schema in schema.sql, idempotent via
CREATE TABLE IF NOT EXISTS.
- POST /api/player-debug unauthenticated (so unpaired players can also
report), rate-limited 10/min/IP, per-field length caps to prevent abuse.
- Dynamic /player HTML route injects window.__playerConfig.debugReporting
based on PLAYER_DEBUG_REPORTING env var (defaults on; =off suppresses
all client telemetry traffic). Other player assets still served static.
- Admin routes (requireAuth + requireSuperAdmin):
GET /api/player-debug/list with pagination and filters
GET /api/player-debug/summary for UA family counts
DELETE /api/player-debug/older-than for manual purge
Admin view (#/admin/player-debug):
- UA family summary at top (Tizen/WebOS/Fire TV/Bravia/Edge/Chrome/etc)
- Filter row: UA contains, date range, has-error checkbox
- Paginated table with expand-row JSON viewer for error_data and context
- device_id labeled (self-reported) since field is unauthenticated input
- Manual delete-older-than button with confirmation dialog
Verified end-to-end with Playwright + Chromium (17/17 checks pass) plus
manual real-browser verification including UA-spoofed Tizen flow landing
rows in the admin view.

The "Custom" tier on the public pricing page was misrendering as a
better-than-Free tier: headline "Custom", price "Free", "Unlimited
devices/storage", "Get Started" button. Root cause is in DB data,
not markup - the 'enterprise' plan row has price_monthly=0 and
max_devices/storage=-1, and the dynamic render in landing.html maps
those to "Free" + "Unlimited" with the wrong CTA.
Fix: filter the 'enterprise' plan out of the public landing render
(client-side, in landing.html only) and replace it with a hardcoded
Enterprise / Custom marketing card whose Contact Us button opens a
new lead-capture modal.
The DB row itself stays - it is actively used elsewhere:
- auth.js: first user in SELF_HOSTED=true mode is assigned to it
- settings.js: white-label feature is gated on enterprise plan
- 1 user (the dev account) is currently assigned to it
- /api/subscription/plans is also consumed by billing.js, settings.js,
admin.js (logged-in surfaces); they keep getting the full plan list.
The filter is scoped to landing.html's render only.
The in-app billing page renders the same plan with the same cosmetic
bug; that's a logged-in admin surface, out of scope for this commit.
Other 4 cards (Free, Starter, Pro, Business) unchanged.
Frontend (landing.html):
- Filter 'enterprise' from public render
- Hardcoded Enterprise / Custom card. Uses .price class with "Let's
talk" + empty .yearly spacer to match Free card's vertical baseline
so the feature list aligns with the paid cards' baselines.
- Modal markup, CSS (mirrored from frontend/css/main.css conventions
since landing.html doesn't import main.css), and inline JS for
open/close/submit/escape/background-click.
- Honeypot field: hidden 'fax_number' input (off-screen + aria-hidden
+ tabindex=-1). Picked over the obvious 'website' name to catch
mid-tier bots that explicitly skip the well-known honeypot names.
Backend (new server/routes/contact.js):
- POST /api/contact/enterprise, public (unauthenticated)
- Rate limited 5/min/IP+path via the existing rateLimit middleware
- Honeypot check: populated fax_number returns 200 silently, no email
- Server-side validation: required fields, email format, screens
1-100000, multi_tenant in {single,multi}, hosting in {hosted,self,
unsure}. Length caps prevent textarea-bomb abuse.
- Sends via existing services/email.js (Microsoft Graph) to
dan@bytetinker.net from the support@screentinker.com Graph sender.
- Log lines: "[contact] enterprise inquiry from EMAIL (COMPANY)
delivered" or "[contact] honeypot triggered from IP; dropping".
Wired in server.js alongside other public routes (before requireAuth).
Build-time tests passed locally:
- Module loads, server boots clean
- Validation: missing fields, bad email, bad multi_tenant, bad
hosting, screens out of range - all return 400 with the right
error message
- Honeypot: populated fax_number returns 200 success, no email sent,
log line confirms drop
- Rate limit: kicks in at 6th request within a minute as expected
- Real end-to-end send: one test submission delivered to
dan@bytetinker.net via Graph (subject "[ScreenTinker] Enterprise
inquiry: ScreenTinker Build Verification", body formatted with all
fields). GRAPH_DEV_RESTRICT_TO was temporarily widened to include
the recipient for the test and restored to dw5304@gmail.com
immediately after.
- Card render order verified against live API: Free (outline,
Get Started) | Starter | Pro (featured, Most Popular badge) |
Business | Enterprise / Custom (Contact Us -> modal).

Short-lived per-device queue covers the TV-flap window (issue #3):
when a device is mid-reconnect, prior code emitted to an empty room
and the event vanished. Now playlist-updates and commands targeting
an offline device are queued and flushed in order on the next
device:register for that device_id.
server/lib/command-queue.js (new):
- pendingPlaylistUpdate: per-device marker (rebuild via builder on
flush -> always fresh DB state, no stale snapshots)
- pendingCommands: per-device Map<type, payload> with last-of-type
dedup (most recent screen_off wins)
- TTL via COMMAND_QUEUE_TTL_MS env (default 30000)
- Active sweep every 30s prunes expired entries
Memory bounds: ~6 entries per device worst case (1 playlist marker
+ 5 command types), unref'd sweep timer.
Wired emit sites (8 total; the four direct socket.emit calls in
deviceSocket register handlers are intentionally NOT queued because
the socket is alive by definition at those points):
- server/routes/video-walls.js (pushWallPayloadToDevice)
- server/routes/device-groups.js (pushPlaylistToDevice)
- server/routes/content.js (content-delete fan-out)
- server/routes/playlists.js (pushToDevices + assign)
- server/services/scheduler.js (scheduled rotations)
- server/ws/deviceSocket.js x2 (wall leader reclaim/reassign)
server/ws/deviceSocket.js register paths now call flushQueue after
heartbeat.registerConnection + socket.join. Existing
socket.emit('device:playlist-update', ...) lines kept - they send
the initial state on register; the flush replays any queued events.
Player's handlePlaylistUpdate fingerprint check dedupes the
overlap.

Connection-stability layer for issue #3. LG webOS WebKit (and other
TV-grade clients) miss Engine.IO pongs under decode load with the
Socket.IO defaults of 25s ping / 20s timeout, causing spurious
transport drops and a connect/reconnect/evict/disconnect loop on
the device. Default polling-first transport adds another fragility
layer via the polling->WebSocket upgrade dance.
- pingInterval / pingTimeout default to 30000 / 30000 (worst-case
dead-socket detection 60s, up from ~45s). Both env-configurable
via PING_INTERVAL / PING_TIMEOUT.
- Player Socket.IO client: transports: ['websocket', 'polling'].
Tries WebSocket first; falls back to polling on the same connect
attempt if WebSocket fails. Polling fallback preserved for
firewall-restricted networks.
App-level heartbeat checker is unchanged and remains the safety net
for clients that miss the transport-level ping/pong window.
Tradeoffs documented in inline comments. README env table extended
with PING_INTERVAL and PING_TIMEOUT rows.

Self-hosters running internal-only deployments don't need the
marketing homepage. With DISABLE_HOMEPAGE=true, requests to /
302-redirect to /app instead of serving the landing page.
Unset/false preserves current behavior.
Requested via discord feedback.
Fix: at connect, enumerate the user's accessible workspace_ids (direct workspace_members + org_owner/admin paths + platform_admin 'all') via new accessibleWorkspaceIds() helper in lib/tenancy.js; socket.join one room per workspace. All 12 dashboardNs.emit sites across deviceSocket / heartbeat / server.js / devices route / video-walls route now route via dashboardNs.to(workspaceRoom(...)).emit() with the workspace looked up from the relevant device or wall. New lib/socket-rooms.js holds the helpers and breaks a circular dependency (dashboardSocket already requires heartbeat, so heartbeat can't require dashboardSocket).
Inbound 6 commands rewired to canActOnDevice(socket, deviceId, tier): request-screenshot is read tier (workspace_viewer+); remote-touch/key/start/stop and device-command are write tier (workspace_editor+). Platform_admin and org_owner/admin always pass via actingAs. Legacy admin/superadmin branch dropped.
Lifecycle note: workspace-switch already calls window.location.reload (Phase 3 switcher), which forces a fresh socket with updated memberships - no per-emit re-evaluation needed.
Smoke tested with 3 simultaneous socket.io-client connections (switcher-test, swninja, dw5304 platform_admin) + direct canActOnDevice invocation for 6 user/device/tier combinations. All 9 outbound isolation cells and all 6 permission gates pass. Fixture mutation: switcher-test's Field Crew membership flipped from workspace_editor to workspace_viewer to exercise the read/write tier split in one login.
Express's req.ip was resolving to a Cloudflare edge address (e.g.
172.70.x.x) for any request fronted by Cloudflare, because trust proxy
was set to '1' — that trusts the immediate hop, which IS Cloudflare.
All activity_log rows from API paths captured the proxy, not the
client. The WebSocket path was unaffected and recorded the real IP.
Two layers of defense:
1. trust proxy now lists Cloudflare's published v4 + v6 ranges plus
loopback / linklocal / uniquelocal (config/cloudflareIps.js). With
this list req.ip resolves to the original client when fronted by
CF, and X-Forwarded-For from any non-trusted source is ignored —
so the value can't be spoofed.
2. New getClientIp(req) helper in services/activity.js prefers the
CF-Connecting-IP header but only honors it when the immediate TCP
peer is itself a trusted address. Same gate as trust proxy, so a
visitor who hits the origin directly with a forged header is
logged at their real address.
Routed all five activity-log call sites (auth login success/failure,
admin password reset, generic activityLogger middleware, and the
in-memory rate-limiter key) through the helper.
Logging-only change. No schema changes. Existing rows are not
modified — fix applies to new entries going forward.
Verified locally:
- Bare loopback hit logs 127.0.0.1 (not a proxy address).
- Helper unit cases including an untrusted peer (203.0.113.7) sending
a forged CF-Connecting-IP correctly fall back to the real peer.

Password reset for other users:
- New PUT /api/auth/users/:id/password endpoint
- Superadmin can reset any local user; admin can reset role=user
members of teams they own only (cannot reset other admins or
superadmins, cannot self-reset — that goes through PUT /me with
current_password)
- OAuth users are excluded (no password to reset)
- Rate-limited 20 req/min/IP to cap blast radius if an admin session
is compromised
- Explicit audit log entry "password_reset_for_user / target: <email>"
on every reset; activity logger's summarizeAction never reads the
password field, so the password value is not stored anywhere
Frontend: Reset Password button in the Admin user table and Settings
> User Management table. Shown only for local-auth users that aren't
the current user; prompts for an 8+ char password.
Widgets visibility fix:
- routes/widgets.js had `const isAdmin = req.user.role === 'superadmin'`
which mislabeled superadmin as admin and silently restricted real
admins (role=admin) to seeing only their own widgets. Now matches
/auth/users behavior: superadmin sees all, admin sees own + public
+ widgets owned by members of teams they own, user sees own + public.
7 new i18n keys (admin.reset_password, admin.prompt_reset_password,
admin.toast.password_min_8, admin.toast.password_reset, and the
matching settings.user.* / settings.toast.* trio). 1024 keys total,
parity 100% across en/es/fr/de/pt.

Landing page (frontend/landing.html):
- Title now includes "Self-Hosted" for that keyword
- Description appended "MIT licensed."
- Keywords aligned to spec (digital signage raspberry pi, digital
signage android tv, video wall software, kiosk software, etc.)
- SoftwareApplication JSON-LD: added applicationSubCategory
"DigitalSignage", license URL, refreshed description
- Image alt text + og:image:alt + twitter:image:alt now include
"open-source digital signage"
- New Resources section above the CTA with 6 cards linking to all
new guides and comparison pages
- Footer rewritten as a 5-column grid (Brand / Guides / Compare /
Project / Legal) with the new internal links
New SEO pages, all dark-themed, mobile-responsive, ASCII-only:
- frontend/css/seo-page.css (shared nav/footer/article/table styles)
- frontend/compare/yodeck-alternative.html
- frontend/compare/screencloud-alternative.html
- frontend/compare/optisigns-alternative.html
- frontend/guides/raspberry-pi-digital-signage.html
- frontend/guides/digital-signage-android-tv.html
- frontend/guides/self-hosted-digital-signage.html
Each new page has unique title/description/canonical, OG and Twitter
card tags, BreadcrumbList JSON-LD, single h1, proper h2/h3 nesting,
visible breadcrumb, comparison table or step-by-step ordered list,
"Related guides" cross-link block, and a CTA.
Sitemap (frontend/sitemap.xml): added all 6 new URLs with appropriate
priority (0.8 for compare pages, 0.9 for guides). Existing landing
(1.0) and legal pages preserved.
Robots (frontend/robots.txt): allow /compare/ and /guides/, disallow
/player (was previously allowed by mistake).
Server (server/server.js): added explicit GET /sitemap.xml and
GET /robots.txt routes ahead of the static middleware so the
Content-Type is guaranteed.

Two pre-existing bugs surfaced during deploy:
- /api/devices/:id/screenshot fell back to a query referencing
screenshots.created_at, but the schema column is captured_at. Threw
SqliteError 500 whenever the in-memory cache was cold (e.g. just
after a server restart).
- The SPA catch-all at /* served index.html for non-/api paths but did
nothing for unmatched /api/ paths — the response hung until the
upstream timeout (524 from Cloudflare at 15s). Now returns 404 JSON.

LOW 1 (notes XSS): device.notes textarea content now goes through
esc(). Notes weren't in the sanitizeBody allow-list at write time, so
HTML in the field would render unescaped on the device-detail page.
LOW 2 (CSP): enabled Helmet contentSecurityPolicy with default-src
'self', script-src 'self', style-src 'self' 'unsafe-inline', plus the
data:/blob:/https: image and media sources the player needs. Strict
script-src blocks <script> injection; script-src-attr 'unsafe-inline'
keeps existing inline onclick handlers working until they can be
refactored to addEventListener (TODO comment in code).
CSP applies to /app and most other paths. Skipped on the public
widget and kiosk render endpoints, the landing page, and /player —
those legitimately need inline scripts/styles. upgrade-insecure-
requests is explicitly disabled so HTTP-only self-hosted LAN
deployments aren't broken.
Refactored two inline onclick handlers in index.html to data-close-
modal attributes wired by a delegated listener in app.js. Was the
only blocker for /app under strict script-src.
LOW 3 (CORS): Express CORS now only allows screentinker.com (and
subdomains) + localhost in production. SELF_HOSTED=true bypasses the
allowlist (operator owns their deployment). Development mode stays
open. Same policy applied to the Socket.IO CORS config which was
previously origin: '*'. Native clients (Android, server-to-server,
kiosk iframes) send no Origin and pass through unchanged.

New content_folders table with hierarchical parent_id and per-user
scoping. content.folder_id added (ON DELETE SET NULL so deleting a
folder drops items back to root). New /api/folders route exposes
list/create/rename/move/delete with cycle detection on move.
Content library UI: breadcrumb navigation, subfolder grid, "+ New
Folder" creates inside the current folder, drag-and-drop content
items onto folder cards to move them, and the edit modal has a
folder dropdown showing each folder's full path.
Per-user scoping is enforced server-side: every folder query
filters by user_id, and folder ownership is checked on both folder
mutations and content.folder_id updates.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Extend the public /api/content/:id/file gate to unlock content referenced
by widgets (previously only playlists unlocked it), so device browsers
and kiosk iframes can fetch logos and background images that widgets
embed.
Security: scope the widget lookup to the content owner's widgets only
(w.user_id = content.user_id). Otherwise a user could unlock another
user's content file by creating their own widget whose config references
the victim's content UUID. The pre-existing playlist gate has the same
shape and is left for a separate fix.
Also adds a 30/min rate limit on POST /api/widgets/preview, which
inlines user content as base64 and is memory-intensive.
Perf note: the widgets.config LIKE scan is O(n). Fine at current scale;
revisit with a content_widget_refs join table if the widget table grows.
