WalkthroughThe LiveKit token endpoint now requires an authenticated user with a tenant ID. It derives token identity from the user, scopes room grants to the tenant, and removes the client-supplied username. The client hook manages tokens in memory and handles room changes and cancellation. ChangesAuthenticated LiveKit token flow
Graphify output ignore
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The endpoint now requires authentication and limits token permissions, but room scoping currently uses a tenant value that may not match the caller’s active session. This can break valid access or create a cross-tenant isolation risk, so the tenant-context fix should land before merge; room-name URL encoding is a smaller follow-up issue.

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
This PR tightens LiveKit token issuance by removing client-supplied identity, enforcing authenticated access, and scoping rooms by tenant to reduce cross-tenant link leakage.
Changes:
- Remove
usernamefrom client token requests and derive identity from the authenticated user on the server. - Add auth guard to the
/api/livekitendpoint and scope room names withtenantId. - Update the token hook to avoid stale tokens when switching rooms.

TIP This summary will be updated as you push new changes.
…tenant GET /api/livekit had no session check, and no middleware covers apps/web. It read roomName and username from the query string and returned a token granting roomAdmin, roomCreate, roomRecord, recorder, roomList and agent, so anyone could mint an admin token for any room under any identity. Put the handler behind authenticatedGuard, derive the identity from the Gauzy session instead of the query string, and drop the six grants the meet UI never used. Room names stay client-provided since they are ad-hoc and shared by link, but are now prefixed with the caller's tenant so a leaked link cannot reach another organization. Also stop caching the token in localStorage: it lived under a single key shared by every room, so switching rooms briefly published local tracks into the room the user had just left.

Review feedback. roomName was interpolated raw into the query string, so a generated base64 name containing "+" reached the route decoded as a space. Build the query with URLSearchParams instead. Trim the room name once when reading it and use that value in the grant, so "abc" and " abc" can no longer resolve to two different rooms.

…adata Review feedback. Clearing the token from a passive effect left one render where the new room was already selected but the previous token was still handed out. Store the room the token was issued for and return it only when it matches the current room, so the swap happens during render instead of one tick later. This also removes the need for the cancellation flag. Neither our code nor @livekit/components-react ever mutates participant metadata, so canUpdateOwnMetadata is dropped from the grant.
The guard also exposes a tenantId read from the auth-tenant-id cookie, which is not httpOnly and can be rewritten from the browser. Scoping the room grant with it would let a caller pick another tenant's rooms, so the route uses the tenant returned by /user/me instead. Two reviewers flagged the unused guard value, hence the note.

Greptile SummaryThis change requires an authenticated tenant user before issuing LiveKit tokens, derives participant identity from the signed-in user, scopes rooms by tenant, and removes client-side token reuse. A refreshable session can still be rejected by the LiveKit endpoint when its access token has expired, which prevents a participant from joining a meeting. The route also retains LiveKit authorization policy that should live in the service layer and uses a mutable token builder under a T-Rex validation blocked
Confidence Score: 4/5The authentication and tenant-scoping changes improve token issuance safety, but refreshable sessions can still lose access to meetings after their access token expires. The LiveKit route, authentication guard, and proxy behavior establish the missing refresh path in the relevant code. A direct cookie-backed execution could not complete because the standalone harness did not expose the supplied cookie to the application helper. Files Needing Attention: apps/web/app/api/livekit/route.ts needs refresh-aware authentication before it issues or rejects a meeting token. The LiveKit grant construction should also move to the core service layer.

@NdekoCode I did not have time to verify it all, but I wonder, if it still be possible to create a rooms where NOT whole tenant have access, but only user who created it and some people he invited!? We want not only global per tenant rooms, but also user private rooms! |
sir @evereq Private rooms still work the way they did. The tenant prefix narrows access, it doesn't open anything up. Room names are still generated per meeting, so two people in the same tenant only meet if they hold the same link. Before this PR anyone with a link could join, signed in or not, and could mint a room-admin token for any name. Now a caller needs the We made real restriction because now a guest from another organisation can no longer join, even with the Also there's no invite list today, and there never was: whoever holds the link gets in.

Require auth on LiveKit token endpoint and scope rooms per tenant
Description
GET /api/livekithad no session check at all, and there is no middleware coveringapps/web. It readroomNameandusernamestraight from the query string and returned a LiveKit token withroomAdmin,roomCreate,roomRecord,recorder,roomListandagentgranted. Anyone who knew the URL could mint an admin token for any room, under any identity.This PR puts the endpoint behind the same guard our other API routes use, takes the identity from the session instead of the query string, and cuts the grants down to what the meet UI actually needs — camera, mic, screen share and chat.
Room names stay client-provided on purpose: they're ad-hoc (
TeamName-Members-nanoid) and shared by link, so there is no persisted room to authorize against. Instead the room is prefixed with the caller's tenant, so a leaked link can't pull someone from another organization into the call. Members of the same tenant still resolve the same link to the same room, and no client change was needed for this — the room lives in the token, not in the component props.What Was Changed

No visual change. The only difference is that the meet no longer renders instantly from a cached token — there's a short wait while the token is fetched, same as it already was on a user's first meeting.
