The client held the Klipy key in VITE_KLIPY_API_KEY, which Vite inlines into
the shipped bundle by design — a build variable can never hold a secret. Move
the integration behind the server:
- New authenticated GET /api/v1/gif/search and /api/v1/gif/trending. The key
comes from the new `gif.api_key` config section (koanf,
OWNCORD_GIF_API_KEY) and never leaves the server.
- Default-off: with no key, both endpoints return 503 GIF_DISABLED so clients
can hide the picker instead of showing a broken one. Auth is checked first,
so anonymous callers cannot probe whether a key is configured.
- Outbound call reuses the existing SSRF-guarded dialer (exported as
plugin.GuardedDialContext) rather than a bare http.Get: resolve once,
reject private/loopback/link-local/CGN, dial only vetted IPs. Redirects are
not followed and the response body is size-capped.
- Only id/title/media_formats.{tinygif,gif}.url are forwarded — decoding into
the narrow struct is the allowlist, so an upstream that echoed the key
could not leak it. Upstream errors become a generic 502 and the key is
redacted from anything that reaches the logs.
- Dedicated `gif:` rate-limit bucket (30/min per IP) so debounced search
traffic cannot exhaust the shared bucket used by password/TOTP endpoints.

After validating every resolved IP, the guarded dial connected only to
ips[0] — an allowlisted dual-stack or round-robin host whose first record
was down hard-failed despite reachable vetted alternatives. The dial now
tries each vetted address in order (all records still validated before
any dial: one poisoned private record refuses the whole request).
Also removes the redundant rejectPrivateAddrs pre-resolves (initial
request + redirect hop): the guarded dial is the authoritative check and
every path flows through it, so the pre-resolve only cost an extra DNS
round trip while re-opening the rebinding TOCTOU it was meant to close.
Folds the W3-2-adjacent double-resolve cleanup from the plan.

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.
Eight focused follow-ups from the medium-severity review bucket. All
in-sandbox tractable; no module changes, no new dependencies.
Performance
- Drop the defensive memcpy in EventPersister.Enqueue. The hub already
passes a fresh slice from wrapWithSeq and the copy was happening under
seqMu, serializing broadcast throughput. Documented the no-mutate
contract on the call site.
Observability
- AppMetrics gains WSEventsPersistErrors counter; the persister run loop
bumps both it and the existing WSEventsPersisted counter via cached
metrics handle.
- Hub.persistEvent now extracts the real event type ("chat_message",
"voice_join", ...) from the wrapped JSON envelope via a small
no-allocation byte scan instead of recording the generic
"broadcast"/"channel_broadcast" label.
- Added OTel spans + ServiceCallDurationMs histogram entries on one
public method per remaining service: DMService.CreateDM,
VoiceService.JoinChannel, InviteService.CreateInvite,
ModerationService.BanUser, BlockService.BlockUser,
UserService.UpdateProfile. Mirrors the existing pattern from
MessageService.SendMessage.
Hardening
- plugin/loader now Lstat-walks each plugin directory and rejects any
symlink, plus refuses an entrypoint that is itself a symlink. The
asset handler's prefix check stays as defense in depth.
- ipAllowed (plugin HTTP capability) now rejects RFC6598 carrier-grade
NAT (100.64.0.0/10), closing a gap in net.IP.IsPrivate which only
covers RFC1918 + RFC4193.
- Registry.activateAll syncs Instance.Enabled := true after a successful
activate so callers reading the in-memory flag see the live state.
Documentation
- defaultYAML now documents the new event_persistence, telemetry, and
plugins config blocks with their defaults and one-line descriptions.
- PHASE_BC_LOCAL_TODO.md ticks off five items (defaultYAML docs ×2,
remaining service spans, registry wiring already-fixed in Pass 2).

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).
