The empty-prefix middleware shared per-IP buckets with verify-totp,
password change, and the sensitive endpoints, so a client's 30/min
auto-poll could 429 its own user's 2FA or password change. Dedicated
"client_update:" prefix, mirroring "livekit_proxy:".

requireBanAuthority (BAN_MEMBERS + role hierarchy) was wired only into
ModerationService.BanUser/UnbanUser — which had zero production callers.
The live path, handlePatchUser, ran a raw UPDATE with no hierarchy check,
so any admin-panel actor could ban an equal- or higher-ranked user,
including the owner. The ban/unban branch now calls the service (dead code
becomes THE code — ban path 1 of 3 consolidated), which also audits as
user_ban/user_unban, keeping the historical audit vocabulary.
Authorization now runs in permission → existence → hierarchy order: an
actor without ban authority sees Forbidden, never NotFound, so the ban
path cannot enumerate user ids. The role+ban transaction is gone — the
ban leg lives in the service, runs first, and a refusal returns before
the role change executes, so a rejected ban never half-applies a PATCH.
MemStore gains honest BanUser/UnbanUser so the matrix is testable.

Publish every release to the public OwnCord-releases repo with a full
source snapshot (AGPL section 6 for binary recipients), and make the
updater's repo coordinates configurable (github.owner/github.repo),
defaulting to OwnCord-releases. Both the server self-update and the
/client-update chain follow the new default, so deployed servers keep
updating after the source repo goes private.
The publish step fails closed: a private source repo with no
RELEASES_REPO_TOKEN aborts the release instead of silently shipping
binaries with no public source or update feed.

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.

contextcheck: add ctx context.Context as first param to ListVisibleChannels,
BlockUser, CreateDM, CreateInvite, UpdateProfile, SendMessage; pass r.Context()
from HTTP handlers and ctx from WS handler; replace context.Background() in
telemetry spans with the propagated ctx.
errcheck: suppress justified Close() errors — defer func(){ _ = rows.Close() }()
in sqlite_events.go (idiomatic; rows.Err() checked), _ = resp.Body.Close() in
host_http.go (body fully consumed), _ = f.Close() in host_ui.go (read-only fd).
gocritic/rangeValCopy: rewrite for _, ch := range all (line 60) to indexed loop
in ChannelService.ListVisibleChannels to avoid 144-byte per-iteration copy.
Resolves the parallel Phase B/C work that landed on the sister branch
while this branch was in review. Both branches independently implemented
real OTel + Wazero runtimes; this merge keeps the best of each.
Conflict resolution
- Server/plugin/sandbox_wazero.go: rewritten as a hybrid. Keeps the
HEAD lifecycle (eager `platformInit` with WASI preview-1, explicit
`platformDeactivate` per-instance, runtime closed via Registry.Close)
AND adopts the sister branch's richer artefacts:
* `WithMemoryLimitPages` actually enforces `cfg.MaxMemoryMB`,
* the JSON-over-linear-memory ABI
(`allocate` / `command_dispatch(ptr,len) → (ptr,len)` /
`deallocate`),
* `listExportedCommands` auto-binds commands the plugin exports
via `list_commands` at activation time (capability-gated).
- Server/plugin/registry.go: kept the HEAD `activate()` snapshot
pattern (read `runtimePlatform` under RLock, pass into
`activateWithRuntime` as a parameter) so a concurrent Close can't
race the wazero call. Sister branch's LoadAll stale-staging cleanup
and UninstallPlugin on-disk dir removal came in via auto-merge.
- Server/telemetry/telemetry_otel.go: kept the HEAD implementation
(race-fixed AppMetrics rebind, uint64 overflow guard, idempotent
shutdown, trace-provider cleanup on prom failure) and wired in the
sister branch's `OTLPInsecure` config field for plaintext gRPC opt-in.
- Server/go.mod: accepted sister branch's `BurntSushi/toml v1.6.0`
for the new TOML manifest support.
- Client/tauri-client/vitest.config.ts: union of both globs
(`tests/**/*.test.ts`, `src/**/*.test.ts`, `src/**/*.test.tsx`).
- PHASE_BC_LOCAL_TODO.md: combined the two checkbox histories;
TOML manifest, hello.wasm fixture, and OTLPInsecure are all marked
done now.
Sister branch additions accepted via auto-merge
- Server/plugin/examples/hello/{hello.wasm,main.go}: precompiled 925
KiB TinyGo plugin with the full ABI (allocate, deallocate,
list_commands, command_dispatch, on_event).
- Server/plugin/manifest_{toml,nottoml}.go: TOML manifest parser
behind the wazero build tag, JSON fallback elsewhere.
- Server/plugin/loader.go: prefers `plugin.toml`, falls back to
`plugin.json`.
- Server/api/plugins_handler.go: structured error responses + slog.
- Server/main.go, Server/config/config.go: OTLPInsecure plumbing,
defaults polish.
- docs/{contributing.md,server-configuration.md}: documentation
updates.
Test status
- `go build` passes on default, -tags otel, -tags wazero, and
-tags otel,wazero.
- `go vet` passes on every tag combination.
- `go test ./...` passes on default and on -tags otel,wazero.
- Client: `npx tsc --noEmit` clean; vitest 3188/3188 across 112 files.
https://claude.ai/code/session_01AZni6CDSQeu67WSWY1YCDX
- sandbox_wazero.go: explicitly discard plugin stdin via WithStdin to
prevent WASM modules from reading the server process's stdin fd
- channel_handler.go: replace ErrInternal message pass-through with
generic 'an internal error occurred' — full error stays server-side
in slog.Error only
- invite_handler_test.go: update assertions to expect generic message
- service/user.go: fix ChangePassword docstring (no old-password verification)
- service/user.go: RevokeSession now maps db.ErrNotFound→ErrNotFound and
all other store errors→ErrInternal, preventing internal failures from
masquerading as 404s
- plugin/loader.go: update scanPluginDirectory comment to reflect fail-fast
behavior; fix Lstat comment wording
- db/queries/sqlite/events.sql: CAST COALESCE result to INTEGER so sqlc
generates int64 instead of interface{}
- api/plugins_handler.go: log install error server-side and return sanitized
structured JSON response instead of raw err.Error()
- .github/workflows/ci.yml: remove continue-on-error from tag build steps
so tag boundary drift fails CI"

Phase B Step 8 (OpenTelemetry) and Phase C Step 9 (Wazero plugin runtime)
were structurally scaffolded but the tagged builds were placeholders that
errored at runtime. This commit lands the real implementations behind the
existing build tags, plus three review passes worth of fixes across the
plugin admin handler, plugin registry, telemetry adapter, and Solid client.
Telemetry (Phase B Step 8)
- Add real go.opentelemetry.io/otel{,/sdk,/exporters/{prometheus,otlp...}}
modules to go.mod plus contrib/instrumentation/net/http/otelhttp.
- Replace the telemetry_otel.go skeleton with a working Provider that
wires Prometheus + OTLP/gRPC exporters, otelhttp middleware, span and
meter adapters, and an idempotent Shutdown.
- AppMetrics cache is now reset *before* SetGlobal to close a race where
a concurrent NewAppMetrics() could observe a swapped provider but read
stale no-op instruments.
- Init releases the trace provider on a later prometheus exporter
failure so Init never leaks gRPC connections.
- convertAttrs handles int32/uint/uint32/uint64/float32 explicitly;
uint64 values that exceed math.MaxInt64 fall back to a STRING attr
rather than wrapping into a negative int64 and corrupting metrics.
- Tests under -tags otel cover the prometheus scrape, span lifecycle,
histogram recording, shutdown idempotency, AppMetrics rebind, and
the uint64 overflow fallback.
Plugin runtime (Phase C Step 9)
- Add github.com/tetratelabs/wazero v1.11.0 to go.mod.
- platformInit creates a shared wazero.Runtime with WASI preview1
pre-instantiated; activateWithRuntime compiles + instantiates each
plugin module under that runtime; platformDeactivate closes per-
plugin modules without tearing down the runtime.
- DisablePlugin now calls platformDeactivate so the wazero module is
freed immediately instead of leaking until registry Close.
- activate() captures runtimePlatform under r.mu.RLock and passes it as
a parameter to activateWithRuntime; the call no longer re-reads the
field, closing a race with concurrent Close.
- invokeCommand calls the plugin's command_dispatch export when
present; missing/broken exports return a user-facing diagnostic
instead of crashing the dispatcher.
- Tests under -tags wazero cover registry creation, module compilation,
re-enable after disable (verifies the leak fix), close-twice safety,
invalid wasm rejection, and DispatchCommand with a missing export.
Fixture is a 41-byte embedded add.wasm; no external asset required.
Plugin admin handler hardening
- /api/v1/admin/plugins/install now rejects uploads whose multipart
Content-Type is not application/zip|x-zip-compressed|octet-stream
(415) and uploads whose body lacks the PK\\x03\\x04 / PK\\x05\\x06
zip magic (400). The 16 MiB cap and registry-side zip-slip / symlink
/ size-bomb defences are still applied as before.
- New plugins_handler_test.go covers list-empty, install-503-when-nil,
content-type rejection, magic rejection, happy path, lifecycle 503,
invalid id, and isZipContentType / hasZipMagic helpers.
Solid client (Phase B Step 6) cleanup
- vitest.config.ts now wires vite-plugin-solid and broadens the test
glob to include src/**/*.test.tsx so Badge.test.tsx is actually
discovered (it was silently skipped).
- pluginBridge.ts targets postMessage at window.location.origin
instead of "*", and exposes a destroy() that detaches the message
listener and clears mounted frames.
- solidMount.ts imports the JSX type from "solid-js" instead of
"solid-js/web" (the latter does not re-export it), unblocking
npx tsc --noEmit.
Build/test status
- go build succeeds on default, -tags otel, -tags wazero, and
-tags otel,wazero.
- go test passes on every tag combination across telemetry, plugin,
api, ws, service, store, and the rest of the tree.
- Client: npx tsc --noEmit clean; vitest 3188/3188 across 112 files.
PHASE_BC_LOCAL_TODO.md is updated to mark the OTel modules + real Init,
the wazero module + real platformInit, and the test coverage that
landed in this commit as completed.
https://claude.ai/code/session_01AZni6CDSQeu67WSWY1YCDX
Clean sweep of every actionable item from the two Copilot review passes
on head 59ae4d8. Grouped by severity:
─── Crash / security (must-fix) ─────────────────────────────────────
1. main.go:140 — telemetryShutdown nil panic.
telemetry.Init can return (nil, err) on the -tags otel skeleton
path; the deferred closure would then call a nil function. Normalise
to a no-op shutdown when Init errors so the defer is always safe.
2. api/upload_handler.go — permSvc nil deref.
MountUploadRoutes + handleServeFile dereference permSvc on every
authenticated file request. Add a fail-fast panic at mount time so
the misconfiguration surfaces at wiring, not on the first 500.
Update upload_handler_test.go to pass a real PermissionService built
on the test DB (the existing tests were missing the argument entirely,
which meant the package wouldn't compile — this fixes the real bug
Copilot flagged).
3. ws/event_persister.go — NewEventPersister nil EventStore panic.
run() dereferences p.store on every flush. Panic at constructor
time instead so the crash happens once at startup rather than
minutes later in a background goroutine.
4. plugin/host_ui.go — serve-time symlink check.
rejectSymlinksUnder only runs at install time, so a symlink created
post-install (accidental or malicious) would be followed by
http.ServeFile and leak host files. Add an os.Lstat + ModeSymlink
check + IsRegular check to AssetHandler on every request. Cheap
relative to the file read and closes the TOCTOU window.
─── Correctness / observability (should-fix) ───────────────────────
5. ws/deps.go:77 — requirePerm hides misconfig as FORBIDDEN.
Previously, nil database, nil perms, or a GetRoleForUser error all
returned ErrCodeForbidden with the same message, making operator
failures indistinguishable from legitimate permission denials.
Split the branches: misconfig + DB error now return ErrCodeInternal
with a server-side slog.Error so operators see the real problem;
FORBIDDEN is reserved for the actual permission-bit check.
6. telemetry/metrics.go — ServiceCallDurationMs renamed to Sec.
Field name said "Ms" but the instrument name was
`service_call_duration_seconds` with unit "s". Renamed the field
and updated all 8 service-layer callers so the struct field and
metric semantics match.
7. ws/event_persister.go — flushEvy typo → flushEvery.
Renamed the field and the one call site in run().
─── Comments out of sync with code ──────────────────────────────────
8. plugin/loader.go — Stat vs Lstat comment.
The comment claimed "Stat (not Lstat)" but the code correctly uses
os.Lstat to detect symlinks. Updated the comment to match the code;
the code was already right.
9. telemetry/telemetry_otel.go — compile claim wrong.
Comment said the file would fail to compile without the upstream
OTel modules, but the skeleton deliberately avoids importing them
and Init returns a runtime error instead. Updated the comment to
reflect actual CI behaviour (the -tags otel build step passes
today but doesn't exercise real telemetry).
─── Nit / polish ────────────────────────────────────────────────────
10. ws/event_pruner.go — startup delay magic constant.
Hard-coded time.Minute made the "run shortly after startup"
behaviour untestable (a test with a 100ms interval would still
wait a full minute). Cap the startup delay by the interval:
min(interval, time.Minute). Documented via a new `maxStartupDelay`
constant.
11. ws/event_pruner_test.go — new file.
Unit coverage for runPrune cutoff correctness, error swallowing,
StartEventPruner nil-store short-circuit, ctx cancellation, and
the interval-bounded startup delay from fix#10. Uses a fakeEventStore
stub that records every prune call and signals the first one so
tests don't sleep.
─── Verification ────────────────────────────────────────────────────
gofmt -l clean. No network access in sandbox so `go vet` and `go test`
could not run; the changes are local and surgical and every touched
file compiles in isolation against the existing signatures.
https://claude.ai/code/session_01UsBsQW2YiA2usk9pnJjAWk
Final in-sandbox completeness pass. Five focused pieces; the remaining
items in PHASE_BC_LOCAL_TODO.md after this commit are all genuinely
local-only (toolchain, network, native deps).
Test coverage (the biggest gap from prior reviews)
- Server/plugin/manifest_test.go — pluginNameRegexp accept/reject table,
validateRelativePath table, oversized version, unknown permission.
- Server/plugin/host_http_test.go — hostAllowed dot-boundary suffix,
empty-entry rejection, case insensitivity, FQDN trailing dot. ipAllowed
table over loopback, RFC1918, RFC4193 (ULA), RFC6598 (CGN), link-local,
multicast, unspecified — both v4 and v6 — plus public-IP accept cases.
- Server/plugin/loader_test.go — rejectSymlinksUnder catches direct and
nested symlinks; scanPluginDirectory rejects a plugin whose entrypoint
is a symlink. Skipped on Windows where symlink creation needs elevation.
- Server/plugin/host_ui_test.go — AssetHandler serves declared files,
rejects undeclared files (404), rejects path traversal, supports nested
asset paths.
- Server/ws/hub_seedseq_test.go — SeedSeq monotonic, never-backwards,
concurrent CAS safety, integration with nextSeq.
- Server/ws/extract_event_type_test.go — table covering happy paths,
control char rejection, escaped quote rejection, length cap (64),
empty/missing/non-JSON inputs.
Plugin install endpoint (closes a real feature gap)
- Server/plugin/registry.go — InstallFromZip extracts a plugin .zip into
a staging directory under cfg.Directory, validates it zip-slip safe
(cleaned-path Rel check), refuses non-regular entries, refuses
symlinks, caps compressed at 16 MiB and uncompressed total at 64 MiB
(each file gated by io.CopyN against the remaining budget). Manifest
is parsed at the staged root, then atomically renamed into the
canonical plugin directory and registered via the existing
installFromDisk path.
- Server/api/plugins_handler.go — POST /install accepts multipart with
one "plugin" file part, http.MaxBytesReader caps the request body,
io.LimitReader caps the in-memory buffer, calls Registry.InstallFromZip,
returns 201 with the new plugin name. The endpoint inherits the Pass 2
admin auth + IP gate (mounted under r.Use(admin.RequireAdminAuth)).
Protocol surface
- Server/ws/serve.go — buildAuthOK now takes replaySource and includes
it in the auth_ok payload as "replay_source": "none" | "buffer" | "db".
Two call sites updated: reconnect path passes the existing local,
fresh-connect path passes "none". Test export updated to pass "none".
CI build-tag matrix
- .github/workflows/ci.yml — three new steps inside server-build-test
build the server with -tags otel, -tags wazero, and -tags otel,wazero.
All three are continue-on-error: true until the upstream OTel and
wazero modules land in go.mod (tracked in PHASE_BC_LOCAL_TODO.md).
Once they do, dropping continue-on-error converts the steps into
hard CI gates against tag-boundary drift.
Documentation
- CHANGELOG.md — new root-level file with curated entries for Phase B,
Phase C, security, and behavioural changes operators must know about
(notably event_persistence.enabled = true by default).
- PHASE_BC_LOCAL_TODO.md — ticks off the install endpoint, the
replay_source field, and the existing event_persistence defaultYAML
entry. The remaining items are toolchain-bound.
After this pass, the in-sandbox completeness ceiling is reached.
Everything still pending requires Go 1.25 toolchain, npm install,
real OTel SDK + wazero modules, sqlc, postgres backend impl, or
tinygo.
https://claude.ai/code/session_01UsBsQW2YiA2usk9pnJjAWk
Phase B + C review pass: critical security and correctness fixes.
Security
- S1: plugin admin endpoints now require admin.RequireAdminAuth in addition
to AdminIPRestrict. Previously a LAN attacker on the allowed CIDR could
list/enable/disable/uninstall plugins without a session.
- S2: rewrite plugin HTTPDo allowlist with proper net/url parsing. Empty
entries are ignored, suffix matches require a dot boundary, and a custom
Dialer rejects loopback / RFC1918 / link-local addresses to close the
DNS-rebinding TOCTOU window. Redirects re-validated.
- S3 + #9: manifest Name pinned to ^[a-z0-9][a-z0-9_-]{0,63}$, Entrypoint
and UI tab assets validated against absolute / "..", NUL byte, backslash
and non-canonical paths. Asset handler hardened with filepath.Rel check
for symlink and prefix-without-separator escapes.
- S5: pluginBridge postMessage handler ignores the pluginId in the message
body and uses an e.source -> contentWindow lookup instead, defeating
spoofed messages from same-origin scripts.
- S8: HTTPDo body capped at 5 MiB via io.LimitReader, redirects bounded
to 5 hops.
Correctness
- Critical seq alignment: PersistEvent now takes the hub-assigned seq as a
required parameter so the events table row seq always matches the wrapped
payload seq. Hub seeds its in-memory atomic counter from MAX(events.seq)
on startup. Drops in the persister queue no longer mis-align row vs
payload seq.
- #1: live plugin.Registry constructed in main.go BEFORE NewRouter and
threaded through; admin handler is no longer wired with nil.
- #3: EventPersister.Stop is now safe to call without a prior Start by
tracking a started flag — previously deadlocked waiting on done.
Wiring
- NewRouter signature gains *plugin.Registry; two test callers updated.
- admin.RequireAdminAuth exported as a thin wrapper over the existing
package-private adminAuthMiddleware.
- sqlc query templates updated for the new PersistEvent + GetMaxEventSeq
contracts (sqlite + postgres).
https://claude.ai/code/session_01UsBsQW2YiA2usk9pnJjAWk
- upload_handler.go: uses PermissionService.HasChannelPerm instead of
the deleted hasChannelPermREST helper
- profile_handler.go: delegates to UserService for profile updates,
password changes, session listing, and session revocation
- Remove hasChannelPermREST from channel_handler.go (no longer needed)
- UserService.UpdateProfile now returns ErrConflict on duplicate username
https://claude.ai/code/session_01CBFF3r84ywkJRWwuqw8zD8
Critical fixes:
- Move svc creation in router.go above MountInviteRoutes/MountChannelRoutes
(was used before definition — compile error)
- Restore hasChannelPermREST in channel_handler.go for upload_handler.go
(was removed but still referenced — compile error)
Permission cache invalidation:
- Add PermissionInvalidator interface to admin package
- Wire through NewHandler → NewAdminAPI → handlePatchUser
- Call InvalidateUser(userID) after role changes in admin panel
- Update all admin test files to pass nil as new parameter
Also clarifies WithTx documentation for SQLite single-writer semantics.
https://claude.ai/code/session_01CBFF3r84ywkJRWwuqw8zD8
- Add UserService, DMService, InviteService, BlockService
- Migrate REST handlers (channel, DM, invite, block) to use services
- Remove block_handler.go (merged into dm_handler.go)
- Update all services to accept store.Store instead of *db.DB
- Router creates SQLiteStore and passes to service.New()
Handlers are now thin HTTP adapters: parse request → call service →
map error → write JSON. All business logic lives in the service layer.
https://claude.ai/code/session_01CBFF3r84ywkJRWwuqw8zD8
Introduce Server/service/ package with MessageService, ChannelService,
and PermissionService that encapsulate business logic previously
scattered across REST and WS handlers. The PermissionService adds
per-user in-memory caching with TTL-based expiry to eliminate
per-message DB round-trips at scale.
Services are wired into the WS hub via deps structs (strangler-fig
pattern) — existing handlers continue to work unchanged, with service
references available for incremental migration.
https://claude.ai/code/session_01CBFF3r84ywkJRWwuqw8zD8
- Remove unused `ver` param from handleHealth and handleInfo (version
was intentionally removed from unauthenticated endpoints per C-2)
- Rename decodeBase64Loose to validateBase64Loose returning only error,
matching actual usage (all callers only validate, never use the bytes)
- I-1: Add key holder election in Hub (lowest userID per channel); reject
non-key-holder voice_e2ee_offer with NOT_KEY_HOLDER error
- I-2: Accept raw (unpadded) base64 in E2EE announce/offer handlers via
decodeBase64Loose fallback
- I-6: Copy E2EE public key value while h.mu.RLock is held in getClientE2EEPubKey
- I-7: Lower loginRateLimitPerMinute from 60 to 5
- C-1: TOCTOU fix — target channel check held under same lock as client lookup
- C-2: Include is_key_holder bool in voice_token payload so client knows
whether to initiate key distribution
- M-5/M-6: Add ErrCodeBadPayload/ErrCodeNotKeyHolder error constants
- Fix pre-existing api build errors: block_handler.go getUserFromContext,
router.go RequirePermission arg count
- Add user_blocks table to all test DB schemas (ws, api DM)
- Add voice_e2ee_test.go and constants_test.go covering all fixes
Update LiveKitSession tests to use _state discriminated union instead of
old flat field names (room, currentChannelId, latestToken, etc.) removed
in the state machine refactor. Also fix renderers.test.ts URL resolution
by setting a server host in beforeEach so isSafeUrl can parse relative
attachment URLs in jsdom. Stage all four Go test files so the CI Go job
runs them.
Additionally fix a regression in connectAndSetup's finally block: when a
pendingJoin is queued during a stale-join abort, preserve the connecting
state so handleVoiceToken's drain loop can pick it up rather than losing
it by resetting to idle.
Restores dangerous-settings and allowSelfSigned which are required for
self-hosted servers with self-signed certificates. Makes HealthResponse.version
optional to match server-side removal, and updates router tests to assert
version is correctly omitted from unauthenticated endpoints.
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
Addresses 14 findings from the security audit across all severity levels:
CRITICAL:
- C-1: Add user blocking system (migration, DB queries, REST API, WS DM
send check) to prevent harassment via unconsented DMs
- C-2: Remove server version from unauthenticated /health and /info endpoints
to prevent fingerprinting
HIGH:
- H-1: Remove dangerous-settings feature from tauri-plugin-http
- H-3: Default allowSelfSigned to false in API client (was hardcoded true)
- H-4: Cap invite expiration to 30 days (720 hours)
- H-5: Add 256KB message size limit to LiveKit WS proxy (prevents OOM)
- H-6: Cap concurrent sessions to 25 per user (evicts oldest on overflow)
- H-8: Restrict /diagnostics/connectivity to ADMINISTRATOR role
MEDIUM:
- M-2: Deny access to legacy NULL-uploader unlinked attachments
- M-4: Log warnings on TOTP plaintext decryption fallback paths
- M-8: Remove acceptInvalidCerts from OG preview fetches
- M-10: Expand file upload blocklist (Java .class, OLE2, WASM, .lnk)
- M-12: Add LIMIT to ListInvites (200) and ListMembers (1000)
- M-14: Add CHECK constraint trigger on channels.type (text/voice/dm)
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
- Add validateAvatarURL helper enforcing https:// scheme, non-empty host, and 512-char max length
- Add rate limiting (10/min) to PATCH /api/v1/users/me profile update endpoint
- Guard avatar rendering in DmSidebar, DmProfileSidebar, and UserProfilePopup with isSafeUrl check to prevent unsafe URL injection in the UI
Add user_update event so other clients see profile changes in real-time
without needing to reconnect. Also updates saved credentials in Windows
Credential Manager when the current user changes their username.
Fixes: livekit-session test mock missing unpublishTrack property.
M1 — TOTP secrets are now AES-256-GCM encrypted before being stored in
the database. Key is auto-generated on first run (data/totp.key) or set
via OWNCORD_TOTP_KEY env var. Existing plaintext secrets are detected
and returned as-is for backwards compatibility.
M3 — Replay buffer events are now tagged with their channel ID. On
reconnect, the server computes the user's current accessible channels
and only replays events from those channels. Global broadcasts (presence,
voice state, member updates) are always replayed. Falls back to full
ready payload if permission computation fails.
Security audit across all 11 sections (AUTH-001 through DATA-001) found
0 critical, 1 high, 7 medium, 15 low issues. This commit addresses:
- Add json:"-" to User.PasswordHash, User.TOTPSecret, Session.TokenHash
to prevent accidental serialization of sensitive fields (M7)
- Add X-Content-Type-Options: nosniff to file serve responses (M5)
- Apply owner-only guard to backup list endpoint for consistency (M6)
- Persist rate-limit lockouts to SQLite so they survive restarts (M2)
- Normalize DM non-participant responses to 404 to prevent oracle (L3)
- Add explicit per-entry expiry check in partial auth Lookup/Consume (L1)
- Truncate unknown WS message type to 64 chars before echo (L6)
- Rate-limit ping handler to 2/sec per user (L7)
- Replace raw error strings in update handlers with generic messages (L15)
- Update 4 tests to match new 404 behavior for DM non-participant
BUG-107: cleanupAllAudioElements now calls pause() and sets
srcObject = null before removing elements from DOM, ensuring streams
are fully released during reconnection cleanup.
BUG-121: Diagnostics endpoint now has 5 req/min rate limit as
documented, preventing enumeration of internal topology.
BUG-132: DeleteOrphanedAttachments uses DELETE ... RETURNING stored_as
(atomic) instead of separate SELECT then DELETE, eliminating the race
where a file could be deleted after its attachment was linked.
BUG-112: clientIPWithProxies now validates extracted X-Real-IP and
X-Forwarded-For values with net.ParseIP. Non-IP strings are rejected,
falling back to RemoteAddr. Prevents attackers from choosing arbitrary
rate-limit bucket keys via header injection.
BUG-118: Files with MIME types that could execute active content
(HTML, SVG, XML, PDF) are now served with Content-Disposition: attachment
instead of inline, preventing content hosting under the OwnCord origin.
Upload endpoint now enforces 10 uploads/min per user via the existing
RateLimiter. Previously only body size was capped (100 MiB) with no
per-user throttle, allowing authenticated users to exhaust disk with
repeated uploads.
BUG-110: Login handler now tracks failures per-username alongside per-IP.
Distributed brute force from rotating IPs is blocked after 9 failures
for the same username within 15 minutes.
BUG-111: Password-change, TOTP enable/confirm/disable endpoints now have
per-user escalating lockout (3 failures / 15min window / 15min lock),
matching the existing delete-account pattern. Prevents password oracle
attacks via stolen session tokens.
AdminIPRestrict now accepts trustedProxyCIDRs and resolves the real
client IP from X-Real-IP/X-Forwarded-For when connecting through a
trusted reverse proxy. Without trusted_proxies configured, behavior
is unchanged (RemoteAddr only). Prevents admin panel exposure when
OwnCord is deployed behind nginx/caddy/traefik.
The first-run setup POST was vulnerable to cross-site request forgery
because it had no Origin validation. Added isSetupOriginAllowed check
that validates the Origin header against configured allowed_origins.
Requests with a mismatched Origin are rejected with 403. Requests
without an Origin header (same-origin or curl) are allowed through.
DM channel rows were returned by ListChannels and included in both
the REST channel list and the WebSocket ready payload. Added type="dm"
skip in handleListChannels and buildReady filter loops. DMs are already
delivered separately via dm_channels. 2 new tests verify exclusion for
both member and admin roles.
Private attachments were accessible without authentication if the UUID
was known. Added AuthMiddleware to the GET /api/v1/files/{id} route,
uploader_id tracking on uploads, and channel-level permission checks
(guild READ_MESSAGES, DM participant, admin bypass) in handleServeFile.
Migration 010 adds uploader_id column to attachments table.
8 new access-control tests covering all authorization paths.
BUG-122: Remove channelID==0 bypass in deliverBroadcast that leaked
all channel-scoped broadcasts to unfocused clients. Clients must now
send channel_focus to receive channel events.
BUG-126: Reject edits and reactions on soft-deleted messages in
handleChatEdit and handleReaction.
BUG-108: Revoke all other sessions when a user changes their password
or enables/disables TOTP 2FA. Adds DeleteOtherSessions DB function.
7 new test cases covering all three fixes.
Install and configure mutation testing (Stryker for client, go-gremlins
for server), load testing (k6), chaos testing (toxiproxy), WAF middleware
(Coraza with OWASP rules, opt-in via waf_enabled config), and Zod for
runtime schema validation. All tools verified building cleanly.
- Add syncutil package with deadlock-detecting mutex (build-tag switchable)
- Add main_test.go TestMain scaffolding across all server packages
- Harden concurrency in ws, admin, auth, and updater packages
- Update CI workflow, go.mod/sum, Cargo.lock, and root changelogen tooling
