LFXV2-1774 Private upcoming meeting pages leaked the agenda (with embedded Google Docs/Sheets links), materials, committee chips, project context, and join details to unauthenticated viewers. The password-on-URL gate was the only check, which made share-links sufficient for full content access. Tighten the policy: for visibility === 'private' + anonymous viewer, return only { id, visibility } from the server and render only the Private badge + sign-in CTA in the UI. The same gate applies to the past-meeting endpoint (previously leaked title/date even when !fullAccess) and the join-URL endpoint (anonymous can no longer fetch the join URL with a valid password URL). Behavior changes for reviewers: - Existing password-bearing share links to private meetings no longer render content for anonymous viewers; they're prompted to sign in. - getPublicPastMeetingById response for private + anonymous is now { meeting: { id, visibility }, project: null, full_access: false } - title/date/recurrence dropped.

709-722: 💤 Low valueConsider hiding the guest form for
restrictedView()to avoid mixed messaging.For private meetings where anonymous access is blocked, the sign-in CTA now correctly says "This is a private meeting / Sign in to view meeting details." However, the guest form section below (with the "OR" divider) is still rendered, implying guest access is possible when it isn't—the server rejects anonymous join URL requests for private meetings.
This isn't a security issue (the server gate is in place), but the UX is inconsistent: the messaging says sign-in is required while also offering a non-functional guest option.

Pull request overview
This PR closes a data-leak on the public meeting detail route (/meetings/:id) by enforcing a strict sign-in gate for private meetings when the viewer is anonymous, ensuring sensitive meeting content (agenda, materials, join details, context chips, etc.) is not exposed via password-bearing share links.
Changes:
- Server: Redacts
/public/api/meetings/:idand/public/api/meetings/past/:idresponses for private+anonymous, and blocks anonymous join-URL retrieval for private meetings. - Client: Introduces
restrictedViewand uses it to hide sensitive sections and show private-specific sign-in CTA copy. - Client template: Wraps key meeting content sections behind
!restrictedView().

Hi Manish 👋
Great fix on a real privacy issue — server-side redaction plus a UI gate is the right defense-in-depth shape, and the strict policy (LFX login required, password-on-URL no longer sufficient) is the correct call. The three-way response shape in getPublicPastMeetingById is cleanly structured, the AuthorizationError on the join-URL endpoint is the appropriate hard fail, and including redacted: true in the success log metadata is a nice observability touch.
The main gaps are (a) running the redaction gate too late so a flaky project lookup converts a valid private meeting into a 404 for anonymous viewers, (b) shared response types still modelling only the pre-redaction shape, and (c) a leftover guest form that contradicts the new sign-in-only policy for private meetings.
3 blocking · 3 minor · 2 nit
Decision: Needs changes before approval — once the controller ordering, type contract, and guest-form gate are addressed this is good to merge.

[blocking] Redaction gate runs too late — a failed project lookup becomes a 404 instead of a sign-in CTA
The private+anonymous short-circuit at line 107 fires only after projectService.getProjectById() (line 64) and its null-check (line 79). If the project lookup returns null (transient upstream failure, deleted project, etc.) ResourceNotFoundError is thrown at line 80 before this gate ever runs — converting what should be a sign-in prompt into a 404 for anonymous viewers.
Two issues:
- Correctness: a private meeting exists and the viewer just isn't authenticated; a 404 is the wrong response.
- Wasted upstream calls:
getProjectById,addInvitedStatusToMeeting, andaccessCheckService.addAccessToResourceall execute before the gate decides to return{ id, visibility }. None of those results are used in the restricted branch.
Fix: short-circuit immediately after the meeting fetch, before the project lookup:
const meeting = await meetingService.getMeetingById(...);
if (!meeting) throw new ResourceNotFoundError('Meeting', id);
// Early exit for private + anonymous — must come before project fetch
if (meeting.visibility === MeetingVisibility.PRIVATE && !req.oidc?.isAuthenticated()) {
return res.json({ meeting: { id: meeting.id, visibility: meeting.visibility }, project: null });
}
// ... rest of the handler (project fetch, access checks, etc.)Same ordering problem exists in getPublicPastMeetingById (see companion comment at line 238).
| // - fullAccess: return the full meeting record (organizers / members). | ||
| // - private + anonymous: strict gate — even title/date are withheld. | ||
| // - otherwise: a minimal field set so the basic UI can render with a sign-in prompt. | ||

[blocking] Same gate-ordering issue in getPublicPastMeetingById
The isPrivateAnonymous flag is evaluated using meeting and req.oidc at line 232, but the guard doesn't short-circuit until the IIFE at lines 239–261 — by which point projectService.getProjectById() has already run (line 191) and its null-check has already thrown ResourceNotFoundError (line 198) if the project is missing.
Result: same correctness failure as in getMeetingById — anonymous users on a private past-meeting URL see a 404 when the project lookup hiccups instead of the sign-in CTA.
Fix: evaluate isPrivateAnonymous immediately after the meeting fetch (before the project fetch) and return the restricted payload there:
const meeting = await meetingService.getPastMeetingById(...);
if (!meeting) throw new ResourceNotFoundError('Meeting', id);
if (meeting.visibility === MeetingVisibility.PRIVATE && !req.oidc?.isAuthenticated()) {
return res.json({ meeting: { id: meeting.id, visibility: meeting.visibility }, project: null, full_access: false });
}
// project fetch, access checks, full response belowSee companion comment at line 113 for the same issue in getMeetingById.

Summary
Fixes LFXV2-1774. The public meeting page (
/meetings/:id) leaked agenda, embedded Google Docs/Sheets links, meeting materials, committee chips, project context, and join details to anonymous viewers when the meeting was markedvisibility === 'private'. The only gate was a?password=URL parameter, which means any share-link recipient could view the full meeting record without signing in.This PR tightens the policy: for
visibility === 'private'+ anonymous viewer, the page renders only the Private badge + sign-in CTA, and the API returns only{ id, visibility }. LFX login is required to see any private meeting content.Changes
Server —
apps/lfx-one/src/server/controllers/public-meeting.controller.tsgetMeetingById: short-circuit private + anonymous → respond{ meeting: { id, visibility }, project: null }and logredacted: true.postMeetingJoinUrl: refuse anonymous join-URL fetch for private meetings (AuthorizationError).getPublicPastMeetingById: existing!fullAccessminimal-fields branch tightened — private + anonymous now gets only{ id, visibility }, project nulled.Client —
apps/lfx-one/src/app/modules/meetings/meeting-join/restrictedView: Signal<boolean>computed signal —meeting()?.visibility === 'private' && !authenticated().@if (!restrictedView()), extend the agenda+materials guard with&& !restrictedView(), add a private-specific copy variant to the sign-in CTA ("This is a private meeting / Sign in to view meeting details").Behavior changes (call out for reviewers)
getPublicPastMeetingByIdresponse shape change for the private + anonymous subcase: previously returnedtitle,start_time,scheduled_*,duration,recurrence,recording_enabled, etc. Now returns only{ id, visibility }(withproject: null,full_access: false).
