J3vbandClaude Opus 4.8 7b178ff30b fix(security): harden server against verified code-review findings
Applies fixes for 20 adversarially-verified findings from a whole-codebase
security review (server side). All Go build-tag variants build, `go vet` is
clean, and the suite passes (the sole failing test, ws TestEmitEvents, is a
pre-existing nil-harness failure unrelated to these changes).

High severity:
- auth: close TOCTOU in TOTP verify rate-limit by recording each attempt
  atomically up-front (was Check-then-Allow), restoring the per-user
  brute-force cap.
- plugin: enforce the CPU/time budget on every WASM guest call via a
  WithTimeout context (WithCloseOnContextDone interrupts runaways); the
  configured budget was previously parsed but never applied.
- api/waf: inspect request bodies for chunked (ContentLength==-1) requests
  so the SQLi/XSS/RCE body rules can no longer be bypassed.
- ws: rate-limit voice_join/voice_leave and voice_e2ee announce/offer, which
  fan out to every participant and could force mass disconnects.

Medium severity:
- api: run bcrypt on the unknown-user login path (no || short-circuit) to
  remove the timing-based username-enumeration oracle.
- ws: verify LiveKit webhooks via the SDK receiver so the signature is bound
  to the body hash (kills forgery/replay).
- authz: require READ_MESSAGES for reactions and for plugin-command
  broadcasts; route the latter through RequireChannelAccess.
- api: cache the client-update signature fetch and rate-limit the endpoint.
- service: propagate DeleteOtherSessions failure from ChangePassword instead
  of silently reporting success.
- api: trust the rightmost non-proxy X-Forwarded-For entry, not the
  client-controllable leftmost one.
- plugin: route auto-registered commands through the conflict-checked
  RegisterCommand; pin the DNS-validated IP for host_http dials
  (DNS-rebinding TOCTOU).
- api: mark access-controlled downloads private/no-cache + Vary: Origin.

Low severity:
- auth: fail closed when a fully-shaped TOTP ciphertext fails GCM auth
  (was returning the ciphertext as plaintext).
- api: apply the livekit-proxy path allowlist to WebSocket upgrades too.
- service: verify attachment ownership before linking (IDOR).
- admin: bound the bootstrap setup invite (5 uses / 24h); re-verify the
  update binary hash immediately before rename+spawn (TOCTOU).
- service: require BanMembers + role hierarchy for moderation ban/unban.

chore: stop tracking the stray Server/owncord-server.exe build artifact.

Test infra: add uploader_id to the hand-rolled ws test attachment schemas and
make MemStore.GetAttachmentByID a no-op lookup, matching production/DB behavior.

J3vb c3a8aa477c fix: resolve 20 code review bugs across Rust, TypeScript, and Go
Critical/High Rust (Tauri client):
- BUG-140: replace .run() with .build() + RunEvent::Exit handler; native error dialog on startup failure
- BUG-141: eliminate PTT thread TOCTOU race with Mutex critical section; add AtomicBool shutdown and catch_unwind
- BUG-144: fix TOFU cert store corruption — read-before-write rollback restores previous fingerprint on save failure (all 3 write sites)
- BUG-145: add VK code range guard (1..=254) in is_key_down; fix cast to (state as i16) < 0
- BUG-147: replace bare spawns with JoinSet; abort_all + drain on exit; unconditional closed event
- BUG-150: add CRLF guard in handle_connection before header rewriting
- BUG-151: wrap header read loop in tokio::time::timeout(10s)
- BUG-158: extract CERTS_STORE/SETTINGS_STORE to constants.rs (eliminate 3 duplicates)
- HIGH-2: PTT thread self-cleanup uses unwrap_or_else defensive pattern
- HIGH-4: ws_send distinguishes Full vs Closed errors; warn log on backpressure

Critical/High TypeScript (Tauri client):
- BUG-142: join-generation counter prevents stale connectAndSetup completions
- BUG-143: replace 8 mutable LiveKit session fields with discriminated union SessionState
- BUG-146: 60s token refresh deadline; cleared on reply or voice leave
- BUG-148: ResizeObserver hoisted to outer scope; disconnect() in destroy() before ac.abort()
- BUG-152: dismissSignal.aborted guard already present (no change needed)
- BUG-153: measureRendered split into two-pass read-then-write; eliminates per-message reflow
- BUG-154: WS dedup cache batch-evicts to 80% on overflow (amortised O(1))
- BUG-157: pendingUpdates replaced with coalesced function-composition slot (O(1) queue depth)

Go server:
- BUG-149: safe two-value type assertion in getOutboundIP with localhost fallback
- BUG-155: broadcast buffer 256→1024; broadcastDrops atomic counter exposed in /api/v1/metrics
- BUG-156: LiveKitHealthCheck and implementations accept ctx context.Context; all call sites pass r.Context() (12 files)
- BUG-159: MaxMessageBytes constant in config/constants.go; replaces 1<<20 literals in serve.go and updater.go
- HIGH-1: cert store rollback reads old value before write; restores previous cert on save failure

All validation passes: go build, go vet, cargo check, npm typecheck

J3vb 4332541b3a fix: return f.Close() error in downloadFile to catch disk-full flush failures 2026-04-03 14:45:03 +02:00
J3vb 0b1d178d31 fix: wire parseChecksumFileAny for Linux checksum lookup and add missing mock export
- updater.go: DownloadAndVerify now uses parseChecksumFileAny with
  checksumEntryNamesForGOOS so the linux/ path prefix produced by the
  release workflow's sha256sum is found correctly (fixes
  TestDownloadAndVerify_Success on ubuntu-latest)
- video-grid.test.ts: add setScreenshareAudioVolume to the
  @lib/livekitSession mock so vitest does not throw on the export
  that VideoGrid.ts imports

J3vb 998e06d947 chore: merge dev — resolve conflicts between Linux support and signing hardening
- release.yml: integrate signing/manifest/changelog steps with new
  multi-platform artifact layout (windows/ + linux/ dirs)
- updater.go: combine Linux tar.gz support with existing signature
  verification; merge platform-aware asset matching into switch
- updater_test.go: keep PR Linux tests + dev signing/manifest tests
2026-04-03 08:59:57 +02:00
J3vb 9e399384c3 fix: suppress gosec false positives in Linux server support
- G204 in proc_spawner_nix.go and proc_spawner_win.go: exePath is the
  server's own validated binary path, not arbitrary user input
- G302 in updater.go: 0o755 is required for the extracted Linux binary
  to be executable
2026-04-03 08:45:45 +02:00
J3vb 9f32736278 fix: resolve all 12 golangci-lint issues
- nilerr: mark intentional nil returns in DecryptTOTPSecret (backwards compat for unencrypted legacy secrets)
- gosec G703: suppress path traversal false positives in backup handlers (paths already sanitized by HasPrefix guard)
- contextcheck: thread context through handleWebhookParticipantJoined/Left; nolint goroutine in handleFreshConnect that intentionally detaches from request context
- errcheck: handle fmt.Fprintf return in handleWAFInterruption
- gocritic elseif: flatten else-if chain in upload_handler access check
- gocritic ifElseChain: rewrite asset name matching as switch in updater
- unparam: remove unused totpKey param from handleLogin (TOTP verification handled by separate handleVerifyTOTP endpoint)

Vladislav Borisov 52a59b064f PR#88 Added server linux support and optimized ci/release workflow for multiplatform server build 2026-04-03 00:04:17 +07:00
jevb f3c9f98b91 fix: resolve 4 server bugs (Phase 1: BUG-085, BUG-087, BUG-090, BUG-091)
- BUG-085: ring buffer EventsSince off-by-one — change < to <= so
  afterSeq == oldestSeq returns nil (triggers full ready payload)
- BUG-087: GracefulStop not idempotent — wrap body in sync.Once to
  prevent double lkProcess.Stop() on concurrent calls
- BUG-090: FTS query truncation at byte boundary — use []rune
  truncation to preserve valid UTF-8 for CJK/emoji input
- BUG-091: updater downloadFile double-closes file on Windows —
  add closed sentinel to guard defer against explicit Close()

and code quality cleanup pass.
2026-04-01 11:38:33 +02:00
jevb 2a62f31c39 test: boost server coverage — auth 60→95%, db 69→81%, config 75→85%
Add comprehensive tests across all Go packages:
- auth: username validation, concurrent rate limiting, TOTP stores, timing
- config: env overrides, default credential detection, voice defaults
- db: search, message queries, special char handling
- api: handler edge cases, error paths, DM/invite/TOTP coverage
- ws: voice handler paths, integration scenarios
- updater: version comparison, timeout handling

6 of 8 packages now at 80%+ coverage.

jevb a40b42bbed fix: resolve 24 critical and high issues from full code & security review
CRITICAL (5):
- Hub panic recovery now calls h.Stop() after 3 panics (ws/hub.go)
- Ring buffer EventsSince returns non-nil empty slice for current seq (ws/ringbuffer.go)
- PTT event listener stores unsubscribe handle to prevent leak (ptt.ts)
- verifyTotp respects config.allowSelfSigned instead of hardcoding (api.ts)
- ptt_listen_for_key uses spawn_blocking to avoid thread pool starvation (ptt.rs)

HIGH - Server (13):
- TOTP rate-limit checked after body decode; counters reset on success
- TOTP enable returns 409 if already enabled (must disable first)
- Global search pre-computes accessible channel IDs for FTS WHERE clause
- DeleteAccount queries roles by name instead of hard-coded IDs
- BackupToSafe uses absClean in VACUUM INTO
- Voice camera slot uses atomic EnableCameraIfUnderLimit DB method
- readPump snapshots voiceChID before unregister for TOCTOU safety
- Voice join sets state after token send; rollback takes broadcast flag
- Updater download uses probe pattern instead of overflow write
- Webhook checks Authorization header before reading body
- Storage.Save adds fsync and fixes double-close
- Default WS origin denies cross-origin (was: accept all)

HIGH - Client (6):
- WS reconnect uses generation counter to discard stale events
- AudioPipeline uses generation counter against stale worklet callbacks
- Screenshare mute state preserved across reconnect (not full leave)
- handleVoiceToken uses iterative loop instead of unbounded recursion
- store.ts re-entrancy guard with pending update queue
- Notification AudioContext cleaned up on logout

Reviewed by 4 parallel agents across Server Core, Server Realtime,
Client & Tauri, and Security. 55 total findings; 24 CRITICAL+HIGH
fixed here, 31 MEDIUM+LOW tracked in vault backlog (T-265–T-295).

- H8: WS message deduplication on reconnect replay (1000-entry Set)
- H9: Admin setup endpoint rate limited (5/min/IP)
- H10: Backup responses return filename only, not full path
- H11: Update binary recovery failure now alerts admin

Medium (17):

- M14: Storage LimitReader off-by-one fixed
- M15: GitHub token only sent to GitHub hosts
- M16: Content-parser ReDoS regex replaced with split approach
- M17: Audio device switch error handling added

Low (11):
- L1: CORS uses configured origins instead of wildcard
- L2: HSTS header added when TLS enabled
- L3: Consistent JSON error responses across all endpoints
- L4: File modtime from stat, not time.Now()
- L5: Malformed invite JSON returns 400
- L6: TouchSession failure logged at warn
- L8: MessageInput timers cleared on destroy
- L9: Log persistence flush errors caught
- L10: Credential save failure surfaced to user

jevb 3e6d36a47b feat: add negative caching to updater to avoid API spam
Failed GitHub API calls are now cached for 5 minutes before retrying,
preventing repeated 502 errors in the logs when the API is unreachable.
2026-03-19 09:49:21 +01:00
jevb 4945bc9ee9 fix: resolve CI failures in server lint and client tests
Server lint (golangci-lint):
- Add package comment to client_update.go (ST1000)
- Remove unnecessary fmt.Sprintf in updater_test.go (S1039)
- Remove redundant |0x00 in rtp_audio_level_test.go (SA4016)

Client tests (vitest):
- Fix messages.store.test.ts: account for .reverse() in
  setMessages/prependMessages (API returns newest-first)
- Fix logs-tab.test.ts: use .log-entry pre selector to avoid
  matching diagnostics <pre> placeholders; add createLogger
  to @lib/logger mock
- Fix settings-overlay.test.ts: add setVoiceSensitivity to
  @lib/voiceSession mock

jevb 01e4d4bec3 feat: client auto-update with Ed25519 signing and dynamic server URL
- Add tauri-plugin-updater and tauri-plugin-process for in-app updates
- Rust commands (check_client_update, download_and_install_update) build
  updater with dynamic endpoint at runtime for self-hosted compatibility
- Server endpoint GET /api/v1/client-update/{target}/{version} translates
  GitHub Releases into Tauri updater JSON format with .sig content
- UpdateNotifier banner component with install/dismiss controls
- CI workflow produces signed .nsis.zip + .sig updater artifacts
- Self-signed TLS support via dangerousAcceptInvalidCerts config

jevb ce4326766a fix: resolve all golangci-lint issues blocking CI server build
Fix 70+ errcheck violations by adding explicit error discards (`_ =`)
for unchecked return values across test helpers and deferred Close()
calls. Remove unused `senderID` field from broadcastMsg and unused
`defaultCleanupMaxWindow` const. Apply De Morgan's law, remove empty
branch, and simplify redundant type declaration per staticcheck.
