Security
- SSRF: async DNS resolver; allow_redirects=False on all outbound clients;
matrix homeserver_url validated on create/update/test; update_provider
and email_bot merge incoming config and reject ***-masked secrets.
- Auth: bcrypt offloaded to asyncio.to_thread; JWT now carries iss/aud +
leeway and rejects missing claims; setup TOCTOU closed inside a
transaction; rate limits extended (default 600/min, 10/min on password
change, 30/min on needs-setup); constant-time login to prevent username
enumeration.
- Config: rejects known dev secret keys; validates CORS origin schemes,
port range, token lifetimes.
- Webhook handlers stream-read body with a 1 MiB cap; Discord 429 retries
bounded (3 attempts, Retry-After capped at 60 s).
- CSP + HSTS added to SecurityHeadersMiddleware.
Async / runtime
- SQLite engine: WAL, synchronous=NORMAL, foreign_keys=ON, busy_timeout,
pool_pre_ping, dispose on shutdown.
- Lifespan shutdown now stops scheduler before closing HTTP session and
disposing the engine.
- Shared aiohttp session locked against concurrent first-caller races;
core NotificationDispatcher accepts and reuses it.
- Storage and scheduled backup writes wrapped in asyncio.to_thread.
- NUT client writes bounded by asyncio.wait_for.
- Telegram poller switched from 3 s short-poll to 30 s interval + 25 s
long-poll (~10x fewer API calls).
Database
- New performance-indexes migration covers every FK/owner column and
hot-path composite (notification_tracker(provider_id, enabled);
event_log(user_id, created_at DESC); webhook_payload_log(provider_id,
created_at DESC); action_execution(action_id, started_at DESC)).
- New schema_version table for future upgrade gating.
- __system__ placeholder user (id=0) seeded so user_id=0 system defaults
satisfy the newly enforced FK; filtered out of /auth/needs-setup,
/api/users, and setup.
- list_notification_trackers rewritten to batched loads (was 1+N+N*M).
- Retention job extended to event_log, webhook_payload_log, and
action_execution; retention days exposed as a setting.
Scheduler
- AsyncIOScheduler job_defaults: coalesce, misfire_grace_time=300,
max_instances=1.
Ops
- uvicorn runs with proxy_headers, forwarded_allow_ips,
timeout_graceful_shutdown; access log suppressed in non-debug.
- FastAPI version string now reads from importlib.metadata.
- New /api/ready endpoint separate from /api/health.
- docker-compose drops the ALLOW_PRIVATE_URLS=1 default, adds mem/cpu/pid
limits, read_only + tmpfs, cap_drop:ALL, no-new-privileges; healthcheck
targets /api/ready.
- CI now runs on push/PR with backend pytest, frontend svelte-check +
build, and a non-push image build; release workflow gated on tests,
publishes immutable sha-<commit> image tag, adds Trivy scan.
Tests
- New packages/server/tests/ with 29 passing tests: config validation,
JWT round-trip + aud/alg=none rejection, SSRF scheme and private-range
enforcement (sync + async), Discord bounded retry, and a lifespan-level
/api/health + /api/ready smoke check.
- Renamed the misnamed services/test_dispatch.py to manual_dispatch.py so
pytest never auto-collects production code.
Frontend
- /login now redirects already-authenticated users to /, shows a distinct
'backend unreachable' banner (en/ru) when /auth/needs-setup fails.
Security
- Sign pending_restore.json (SHA256 stored in AppSetting, verified on
startup apply) + refuse path outside data_dir, tighten to 0600.
- Require same-origin Origin/Referer on POST /api/backup/apply-restart —
Bearer-in-localStorage is CSRF-reachable from any XSS'd admin tab.
- Bump token_version on role/username change and admin password reset so
demoted admins lose admin in already-issued JWTs. Guard last-admin
TOCTOU via COUNT + post-commit re-check that rolls back a race.
- SSRF guard (validate_outbound_url) in ImmichClient.__init__ and the
external_domain setter — admin-mutable URLs were bypassing the check
that webhook/slack/discord paths already used. Dev restart script now
sets NOTIFY_BRIDGE_ALLOW_PRIVATE_URLS=1 so homelab Immich still works.
- Redact + cap Immich error bodies to ~120 chars before they flow into
ActionExecution.error / EventLog.details (both UI-visible).
- Deny-list sensitive keys (api_key / token / secret / password /
authorization / cookie / ...) in template-context merges so a rogue
template can't exfiltrate provider creds via {{ api_key }}.
- Cap user-controlled Immich search params (query ≤256, person_ids ≤50,
size ≤100) so a Telegram listener can't DoS upstream.
- Stream upload reads with running byte counter + content-length precheck
instead of buffering the full body and then rejecting.
- Log Telegram parse_mode fallbacks instead of swallowing silently;
template escape bugs now surface in server logs.
- Rollback partial imports on pending-restore failure (error recorded on
a fresh session).
Performance
- Fix N+1 in _refresh_telegram_chat_titles: single IN query instead of
session.get per chat.
- Parallelize album + shared-link fetches in test_dispatch (asyncio.gather)
and per-receiver Telegram test sends in notifier (semaphore 5).
- Early-exit collect_scheduled_assets(limit=0) so the periodic-summary
test path skips full per-album filter/sample (was O(album_assets)).
- Emit explicit CREATE INDEX IF NOT EXISTS for event_log user_id /
action_id / provider_id so the first boot after upgrade isn't left
unindexed for the dashboard query.
- Add AbortController timeout (120s) to fetchAuth so uploads/downloads
don't hang indefinitely.

- Skip token clear/redirect on 401 for unauthenticated requests
- Fix typo in test secret key in restart-backend script
- Remove completed plan documents (entity-relationship-refactor, ux-notification-improvements)
- Remove top paginator from dashboard events, keep only bottom
- Fix test message locale: pass UI locale to email/matrix bot tests
- Convert webhook auth mode from text input to icon grid selector
- Generate secure UUID tokens for webhook URLs instead of sequential IDs
- Move Recent Payloads into per-provider expandable container (lazy-loaded)
- Make template config languages dynamic via app settings instead of hardcoded
- Change default dev port to 5175
- Route scheduled/memory test sends through the same NotificationDispatcher
the watcher uses — identical template rendering, media handling, caching
- Add preview_url field to MediaAsset (transcoded mid-size), separate from
thumbnail_url (small) and full_url (original). Dispatcher prefers preview_url
- Fix sendMediaGroup cache: extract file_ids from Telegram response and store
via async_set_many so repeat sends use cached file_ids
- Parallelize asset downloads in _send_media_group with asyncio.gather
- Filter unprocessed assets (archived/trashed/offline/no-thumbhash) at album
parse time in ImmichAlbumData.from_api_response
- Extract shared asset_to_media + collect_scheduled_assets into asset_utils.py
(single source for test dispatch and future real scheduler)
- Respect tracking config filters: limit, asset_type, favorite_only, min_rating
- Random asset sampling for scheduled sends
- Memory mode: "On This Day" date filter (same month+day, previous year)
- Skip dispatch when no matching assets found
- Remove ~250 lines of duplicated send logic from notifier.py
- Fix restart-backend.sh: proper env var export, Python path resolution, error log
Add broadcast target type that fans out notifications to multiple
child targets. Dispatch expands broadcast into children in
load_link_data() — dispatcher stays unaware. Children can be
toggled on/off via disabled_child_ids in config.
Also: dashboard provider card smaller font for names, scroll-to-form
on target edit, broadcast nav tab with counter, flag_modified fix
for JSON column updates, CLAUDE.md nav tree docs.
Replace all if/else chains keyed on provider type strings with a
descriptor-driven architecture. Each provider type (immich, gitea,
planka, scheduler, nut, google_photos) has a descriptor in
frontend/src/lib/providers/ that declares config fields, event
tracking fields, collection metadata, validation, and hooks.
Components now use getDescriptor(type) and render dynamically.
Dashboard provider card shows provider name + type when global
filter is active. Grid-items derived from registry.
Chat language:
- Added language_code field to TelegramChat model + migration
- Saved from message.from.language_code on webhook/polling
- Displayed as badge on bot chat cards and target receiver items
- Resolved from DB in target API response (works for existing receivers)
- Shown in chat picker dropdown (desc includes language)
EntitySelect improvements:
- Tracker-target link selector shows all targets, already-linked ones
appear disabled with "Already linked" hint
- Receiver chat picker shows already-added chats as disabled
Dev scripts:
- scripts/restart-backend.sh and restart-frontend.sh
- Updated .claude/docs/dev-servers.md to reference scripts
