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.

HIGH 1 (teams IDOR): POST/DELETE /api/teams/:id/devices now require the
caller to own the device before assigning or detaching it. Without this
check, any team member could pull any device into their team via UUID
guess and gain remote-control access.
HIGH 2 (schedules IDOR): PUT /api/schedules/:id now re-verifies
ownership of every changed target field — device_id, group_id,
content_id, widget_id, layout_id, playlist_id. Previously only the
schedule owner was checked, letting users fire arbitrary content on
victim devices via update.
HIGH 3 (filename XSS): file.originalname captured by multer bypassed
sanitizeBody. New safeFilename() wraps every INSERT path (multipart
upload, remote URL, YouTube). Frontend sinks now go through esc() in
content-library.js, device-detail.js, video-wall.js. Web player gets
an inline escHtml helper for its info overlay where filenames, device
name, and serverUrl land in innerHTML.
HIGH 4 (kiosk public XSS): config.idleTimeout is now coerced via the
existing safeNumber() helper at both interpolation sites. A crafted
value with a newline can no longer escape the JS line comment to
inject arbitrary code into the public render endpoint.
HIGH 5 (folder DoS): POST /api/folders enforces a per-user cap of 100
folders (429 on overflow). Superadmin exempt.
MED 1 (SSRF): ImageLoader.decodeUrl rejects any URL scheme other than
http(s) so a malicious remote_url can't read local files via file://.
On the server, validateRemoteUrl() is extracted and now also runs on
PUT /api/content/:id remote_url updates — previously the SSRF check
only fired on POST.
MED 2 (fingerprint takeover): the WS device:register fingerprint
reclaim path now rejects takeover while the target device is online or
within 24h of its last heartbeat. A leaked fingerprint can no longer
hijack an active display.
MED 3 (npm audit): bumped uuid 9.x -> 14.0.0 (v3/v5/v6 buffer bounds
CVE; we only use v4 so not exploitable, but clears the audit). path-
to-regexp resolved to 0.1.13 via npm audit fix. 0 vulns remaining.
MED 4 (folder admin consistency): ownedFolder() and the content.js
folder_id move check now both treat only superadmin as privileged,
matching GET /api/folders. Previously a plain "admin" could rename
or delete folders they couldn't see, and could move content into
folders they couldn't list.

multer/busboy decode multipart filename headers as latin1 by default,
which mangled umlauts and other non-ASCII characters end-to-end
(Größe.jpg arrived as Größe.jpg and was stored that way). Setting
defParamCharset: 'utf8' on the multer options makes the entire
upload pipeline consistent UTF-8.

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.

Server-side: when a device reconnects on a fresh socket while the old
TCP zombie is still around, the old socket's eventual disconnect handler
flipped the device offline and removed the new heartbeat entry. Now we
proactively evict any prior socket on register and ignore disconnects
from sockets that are no longer the registered one for that device_id.
Frontend: dedupe devices by id from the API response and only render
each device in the first group it belongs to (multi-group membership
is still tracked for the Manage modal).

When DISABLE_REGISTRATION=true (or 1), POST /api/auth/register returns
403 with a clear error. OAuth endpoints (/google, /microsoft) also
refuse to auto-create new accounts — existing OAuth users can still
sign in. First-user setup (empty users table) is always allowed so a
fresh install can still be initialized.
GET /api/auth/config now returns registration_enabled so the login
view can hide the "Create Account" button and the trial banner when
registration is off. Absence of the flag is treated as enabled for
back-compat with older servers.

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.

Lobby-style tenant/room directory with vertical marquee, seamless loop via
content cloning, pixel shift + bg pulse for anti-burn-in, rotating background
images with crossfade. Supports logo, title, footer, subtitles per entry,
and Available (green) state. All user strings rendered via textContent in
browser — no server-side HTML escaping of entries needed.
Also refactors render dispatch into renderWidgetHtml() and adds a POST
/preview endpoint that inlines user-owned image content as base64 data
URIs so the editor can preview unsaved widgets. Preview is gated by:
- image/* MIME only
- 10 MB size cap
- user_id ownership check
- path traversal guard via basename + resolve
Unknown widget_type on /preview returns 400.

Adds a per-user Account section in Settings with name edit and password
change. Password change requires current password; local auth only.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
scripts/reset-admin.js signed a JWT with a synthetic id ("recovery-XXX")
and instructed the operator to paste it into localStorage. But the
requireAuth middleware always SELECTs the user row by id, so every
authed API call under the recovery token returned 401 "User not found"
and the recovery flow was effectively dead.
Fix:
- reset-admin.js now sets a `recovery: true` claim on the JWT.
- requireAuth / optionalAuth short-circuit the DB lookup when
decoded.recovery === true and synthesize a req.user record in
memory (role: admin, plan_id: enterprise). The synthetic user is
never persisted, so FK-constrained writes that expect a real
user (creating devices, etc.) will still fail — which is fine,
recovery is only meant to let the operator reset a password or
create a fresh admin via the Settings UI.
Security: a recovery token still requires the jwtSecret to sign,
so only someone with filesystem access to the server can mint one.
Token TTL remains 1h.

The SW was causing "unexpected error" on video/image fetches due to
range request handling, opaque response caching, and stale SW races.
Fix: SW now ONLY caches player page + socket.io JS for offline boot.
Content files are left to browser native HTTP cache (server already
sets Cache-Control: public, max-age=2592000, immutable).
Also: auto-reload player when new SW activates so deploys take effect
immediately without manual hard refresh.
Bumped cache to v5 — activate purges all old caches (including the
broken rd-content-v1 content cache).

Bug 1 (SW): Rewrote service worker fetch handler:
- Skip range requests (video seeking) to avoid caching partial responses
- Skip non-GET requests entirely
- Use ignoreSearch on cache match to avoid query-param misses
- Don't cache opaque cross-origin responses
- Outer catch on Cache API failures
- Don't intercept catch-all requests (let browser handle natively)
- Bump cache version to v4 to purge broken cached responses
Bug 2 (auth): Playlist refresh register was missing device_token,
causing auth rejection every 5 minutes. Fixed by including token

Schema: add status and published_snapshot columns to playlists table.
Migration snapshots all existing playlists as published (idempotent via schema_migrations).
Devices always receive the published_snapshot, not live playlist_items.
Edits from device-detail/groups auto-publish immediately (display updates instantly).
Edits from playlist detail page go to draft (requires explicit publish).
POST /playlists/:id/publish snapshots and pushes to all devices.
POST /playlists/:id/discard reverts playlist_items from published snapshot.
Content deletion scrubs references from all published snapshots.
Frontend: draft badge in playlist list, prominent yellow banner with publish/discard
buttons on playlist detail and device detail pages.

Follows up on the security audit remediation (afbe113) which added
device_token auth to the WebSocket /device namespace.
Android player (ServerConfig.kt, WebSocketService.kt):
- Persist device_token in EncryptedSharedPreferences alongside device_id
- Send device_token in device:register on reconnect and playlist refresh
- Save/overwrite token from device:registered response (handles legacy
devices getting their first token)
- Handle device:auth-error by clearing credentials and showing pairing screen
- clearDeviceCredentials() method wipes device_id, device_token, is_paired
Web player (player/index.html):
- Save deviceToken in localStorage config from device:registered response
- Send device_token in register() payload on reconnect
- Handle device:auth-error and device:unpaired events — clear config and
show re-pair UI

New schema_migrations table (id TEXT PK, ran_at INTEGER) tracks which
one-time migrations have executed. The Phase 2 playlist migration now
checks for 'phase2_playlist_migration' in this table instead of
inferring state from devices.playlist_id. Records the migration ID
after successful completion. Eliminates ffprobe overhead on subsequent
startups.

Migration (database.js): switched from sync execFileSync to async execFile
with promise wrapper, matching the pattern in playlists.js. Probes each
video content item, backfills content.duration_sec, and uses the real
duration in playlist_items. Falls back to the assignment's original
duration_sec if the probe fails or content isn't a video.
V1 import (status.js): moved assignment-to-playlist conversion out of the
synchronous db.transaction() so async ffprobe can run. Content files are
already on disk from the transaction, so probing works. Same fallback logic.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Videos were getting the default 10s from the assignments table. Now ffprobe

If a video's duration_sec is NULL in the content table (e.g. ffprobe

When adding a content item to a playlist without an explicit
