Summary

Cherry-picks the fixes from new-test-branch onto current main (with -x, so original hashes and authors are preserved), so main keeps the Tasks and Student Management work while gaining these fixes.

What's included

Security (broken access control)

  • Stop returning password hash/salt in auth responses
  • Profile photo, achievements, skills and feedback are bound to the logged-in user, not client-sent IDs
  • Feedback viewing is admin-only; position creation is role-gated
  • Event updates only accept allow-listed fields; role comes from the session
  • Batch edits restricted to the batch initiator
  • Analytics: authenticate before authorising
  • Server refuses to boot without JWT_SECRET_TOKEN

Stability

  • MongoDB-backed session store (sessions survive restarts) and cookie settings
  • Server starts without Google OAuth credentials
  • Certificates are generated before a batch is marked approved, so a failure leaves it retryable
  • Puppeteer loaded via dynamic import; optional PUPPETEER_NO_SANDBOX
  • Duplicate /api/announcements mount removed

Frontend

  • PresidentDashboard uses real /api endpoints
  • Direct /certificates and public events pages no longer crash (SidebarProvider)
  • Dead service calls removed, legacy home links fixed, lint warnings cleared

Build / CI

  • Tailwind v4 compiled via CLI before the build
  • Root package.json with test/lint/build scripts; backend lint and build scripts
  • Docker REACT_APP_BACKEND_URL build arg; CI passes SESSION_SECRET and health-checks the backend
  • Backend port standardised on 8000 in docs

Conflict resolutions

  • certificates.service.js (3 commits): kept main's Cloudinary upload (uploadTocloudinary) and did not take the alternative upload helper. The controller, renderPdf.js and Dockerfile parts of that commit were kept.
  • userIcon.jsx: kept main's "no literal undefined" fix.
  • One extra commit: allow import() in the backend ESLint config (eslint-plugin-node v11 flags it).

Deployment notes

Required env vars: SESSION_SECRET, JWT_SECRET_TOKEN, MONGODB_URI (session store). The server will not start without the first two.

Testing

  • Backend: npm run lint, npm run build, npm test (5/5)
  • Frontend: npm run lint, npm run build, npm test (3/3)
  • Manual: login, Tasks page, event creation, direct /certificates
  • Manual: Students page, public events page (logged out)
  • Manual: full certificate batch approval.

Summary by CodeRabbit

  • New Features

    • Administrators can access feedback through a dedicated page.
    • Event listings now support guests, and event pages use role-appropriate navigation.
    • Certificate and batch pages now display within the app’s navigation layout.
  • Bug Fixes

    • Feedback submissions are attributed to the signed-in account, and anonymous feedback hides its author.
    • Batch edits are limited to their initiator, and certificate generation must succeed before final approval.
    • Profile, skill, and achievement updates apply to the appropriate account.
    • Dashboard counts and recent activity now reflect the latest event and booking data.

Ashish-Kumar-Dash and others added 30 commits October 3, 2026 05:08
- set parserOptions.ecmaVersion=2022 so optional chaining parses
- enable jest globals and allow test-only devDependencies
- declare node engines (>=18)
- drop unused imports/vars flagged by no-unused-vars

(cherry picked from commit 610fb29)
- remove unused imports/vars flagged by no-unused-vars
- fix exhaustive-deps warnings in useCallback/useEffect
- StudentPanel: move participants/studentIds out of render, add useMemo
- drop unused Field/inputStyle/InfoTile/labelColor helpers in Requests modals

(cherry picked from commit a13d002)
- mock axios via module factory so <App/> renders in jsdom
- assert unauthenticated users land on the Login page
- userIcon: guard undefined academic info instead of printing 'undefined'

(cherry picked from commit f3cc2d6)
…ntend

CRA inlines REACT_APP_* vars at build time, so the backend URL must be
available during the nginx image build, not just at runtime.

(cherry picked from commit 56b58e6)
The dashboard called dead routes (/room/requests, /events, /tenure,
/api/activities/recent) via bare fetch. Use the shared authenticated
axios instance against /dashboard/stats, /rooms/bookings, /events/latest.

(cherry picked from commit 0eb8197)
CertificatesPage uses useSidebar(), which throws outside a provider.
Only the /dashboard layout supplied one, so deep-linking to
/certificates crashed. Mirror Dashboard.jsx and wrap the route.

(cherry picked from commit 7f75672)
eslint v8 auto-loads eslint.config.mjs whenever present, silently
replacing the react-app config used by the build. The flat config only
enabled two react rules (no no-unused-vars, no react-hooks), so lint
was weaker than CI. Removing it lets eslint fall back to the package.json
eslintConfig (react-app).

(cherry picked from commit 9f5919c)
The backend mounts dashboard/rooms/events under /api/*, so the three
calls returned 404 and every stat stayed at zero.

(cherry picked from commit 6bd7a31)
Added MongoDB session store and updated session configuration for HTTPS handling.

(cherry picked from commit 45374ca)

Walkthrough

The pull request updates backend authorization and request handling, frontend routes and state behavior, and application runtime and build configuration. It also changes the backend port to 8000 and adds deployment checks for that endpoint.

Changes

Backend request behavior

Layer / File(s) Summary
Identity and access handling
backend/controllers/achievementController.js, backend/controllers/skillController.js, backend/controllers/profileController.js, backend/controllers/feedbackController.js, backend/models/schema.js, backend/routes/*
Controllers derive ownership and authorship from authenticated users, enforce profile ownership, and omit sensitive or anonymous author data from serialized responses. Routes add authentication and role checks.
Event and certificate batch behavior
backend/controllers/eventControllers.js, backend/controllers/certificateBatchController.js
Event updates accept specified editable fields and use authenticated role information. Batch edits check the initiator, and final approval generates certificates before changing batch status.

Frontend routes and state

Layer / File(s) Summary
Event access and route placement
frontend/src/Components/Events/EventList.jsx, frontend/src/hooks/useEvents.js, frontend/src/routes/*
Guest event requests use the general events endpoint, and guest event tiles use registration actions. Feedback moves to an admin-protected route; event and certificate pages receive sidebar configuration.
Batch student and signatory state
frontend/src/Components/Batches/*
Batch components derive student IDs from form data or event participants and refresh data when the current user ID changes. Signatory initialization checks updated form dependencies.
Dashboard and request data
frontend/src/Components/President/PresidentDashboard.jsx, frontend/src/Components/Requests/*
The president dashboard uses the shared API client for stats, bookings, and events. Request effects update their dependencies, and unused request-modal helpers and imports are removed.
Navigation and frontend utilities
frontend/src/Components/OldComponents/Home.js, frontend/src/Components/Certificates/CertificatesList.jsx, frontend/src/services/*, frontend/src/Components/common/userIcon.jsx
Dashboard navigation and position requests change. Student lookup helpers are removed, and certificate and profile components receive the listed cleanup or state changes.

Runtime and build configuration

Layer / File(s) Summary
Backend sessions and PDF runtime
backend/index.js, backend/models/passportConfig.js, backend/services/certificates.service.js, backend/utils/renderPdf.js, backend/Dockerfile
The backend requires a JWT secret, stores sessions in MongoDB, and configures cookies based on HTTPS status. Puppeteer loads when PDF generation runs and can use the installed Chromium executable.
Build and deployment setup
.github/workflows/deploy.yml, docker-compose.yml, frontend/Dockerfile, backend/package.json, package.json, README.md, backend/.env.example
Deployment checks the backend on port 8000. Frontend builds receive the backend URL, and root scripts run backend and frontend test, lint, and build tasks. Setup guidance documents required secrets and port 8000.
Frontend build and validation
frontend/package.json, frontend/src/*, frontend/eslint.config.mjs, .gitignore
Tailwind CSS builds a minified stylesheet before start and build commands. The app imports that output, and the app test checks for the Login heading.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 344eb

This change improves access control, but several deployment and workflow issues should be fixed before merge. Certificate approval may fail in the container. A deployed frontend may not know where the backend is. Login may not persist in some HTTPS setups. A failed approval can leave orphaned approved certificates. The admin feedback page also breaks when a card is selected.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 344eb

The access-control changes strengthen important boundaries. However, certificate generation now exposes approved certificates before final batch approval is committed, including when generation subsequently fails. Authentication and ownership checks limit the affected scope, but they do not preserve this approval invariant. Deployed HTTPS and proxy settings also remain unconfirmed.

Retained concerns

  • Medium · security · observed: Certificate issuance now precedes the atomic final-approval transition. Each successful recipient receives a persisted Approved certificate whose URL is returned without checking batch approval. If a later recipient fails or the final update fails, previously issued certificates remain accessible despite the batch not completing approval. Concurrent final-approval requests can also render and upload before one loses the atomic update. The base flow required a successful approval transition before generation. Exact approver authorization and unique certificate indexes limit who can trigger issuance and prevent duplicate rows, but do not bind externally visible issuance to committed approval.
Security review details

Security Blast Radius

  • observed — The certificate concern affects issuance records and uploaded PDFs for batches processed by their designated final approver. Initiation requires authenticated admin access and an exact approver match; certificate retrieval is authenticated and scoped to the recipient's user ID. The observed path is not an anonymous issuance or arbitrary-user certificate read.

Security Findings and Attack Paths

  • inferred — A final-approval attempt can successfully issue one recipient's certificate and then fail for another recipient, leaving the batch pending while the first recipient can obtain an Approved certificate URL. Concurrent approvals can also perform issuance before one receives a conflict. This is a PR-introduced publication-order regression, not evidence that an unauthenticated attacker can become an approver.

Trust Boundaries and Controls

  • observed — Backend authentication precedes the inspected feedback and registration role checks. Event registration uses the authenticated user's ID, applies an atomic capacity predicate when configured, and uses add-to-set participant updates. These registration controls and the public event route predate the changed guest client path.
  • observed — Google OAuth strategy registration is conditional on configured credentials. When configured, the existing institution-email check and STUDENT account-creation role remain. OAuth routes still reference the named strategy; the change does not add an alternate identity acceptance path.

Resilience and Maintainability Implications

  • observed — Batch edits now enforce initiator ownership, but issuance reads a mutable snapshot and the final approval predicate checks only batch ID, approval level, and approver identity. It does not bind completion to the recipient, template, or signatory version used for generation.

Hardening Proposals

  • proposed — Use an atomic issuance reservation tied to an immutable batch version, stage generated certificates until approval completion, and publish recipient URLs only after that completion. Define idempotent recovery and compensation for partial issuance, interruption, and conflicting edits rather than relying solely on unique certificate rows.
  • proposed — Document and validate the deployed HTTPS termination point, trusted proxy path, and session-store environment isolation as explicit authentication deployment requirements. The frontend URL alone should not substitute for evidence of that topology.

I’m a rabbit with a checklist, hopping through the code,
Port eight thousand greets me on the backend road.
Secure sessions settle in; the browser builds with care,
Guest events and batch details now find their proper lair.
I nibble one last carrot, then bounce away with glee!

Use a Node image supported by Puppeteer.

Both stages use node:18-alpine, but the declared puppeteer@^25.2.1 dependency requires Node >=22.12.0. The new Chromium setup does not resolve that runtime incompatibility. Update both base images and the backend Node engine declaration to a supported version. (raw.githubusercontent.com)

Inline comments:
Review comments at @backend/controllers/certificateBatchController.js:
- Around line 550-551: Update the level-1 approval flow around
generateCertificates(batch) to claim the final-approval transition with
findOneAndUpdate before generating certificates. If generation fails, restore or
otherwise recover the batch state and remove any partial certificate records so
failed approval leaves no approved certificates attached to a submitted batch.

Review comments at @backend/controllers/eventControllers.js:
- Line 490: Update the coordinator identity used for the organizational-unit
lookup in the event controller to use the authenticated user’s
personal_info.email, matching the identity field used in analyticsController,
rather than req.user.username.

Review comments at @backend/Dockerfile:
- Line 34: Update the Puppeteer launch in generateCertificates to conditionally
pass --no-sandbox and --disable-setuid-sandbox when PUPPETEER_NO_SANDBOX is
"true"; leave the launch arguments unchanged otherwise.

Review comments at @backend/index.js:
- Around line 37-39: Update isHostedOverHttps so cookie.secure reflects the
backend’s HTTPS deployment or trusted request protocol, not FRONTEND_URL;
preserve the requirement that production uses HTTPS and ensure HTTP backend
requests do not suppress session-cookie issuance.

Review comments at @backend/models/passportConfig.js:
- Line 17: Update the `/google` and `/google/verify` routes in `auth.js` to
check for both Google credentials before calling
`passport.authenticate("google")`; when either is absent, return a controlled
disabled-service response instead of invoking an unregistered strategy. Reuse
the configuration check from `passportConfig.js`.

Review comments at @frontend/Dockerfile:
- Around line 11-12: Ensure the frontend image build receives a nonempty
REACT_APP_BACKEND_URL before npm run build; update the deployment workflow’s
docker build invocation to pass its deployment API URL, or make the Docker build
fail when the argument is missing.

Review comments at @frontend/src/Components/Batches/batches.jsx:
- Line 94: Update the effect that calls fetchData when isUserLoggedIn?._id
changes to clear the previous batch list and prevent results for an outdated
user ID from being applied; use effect cleanup or verify the requested ID before
updating state.

Review comments at @frontend/src/Components/Batches/StudentPanel.jsx:
- Around line 31-33: Update the selection initialization around `ids` and
`selectedEvent.participants` to apply the event default only when no saved
student selection exists, preserving an explicitly saved empty `form.students`
selection when reopening the panel.

Review comments at @frontend/src/Components/Events/EventList.jsx:
- Line 115: Update the guest action in EventList’s userRole conditional so
guests are directed to sign in before registering, rather than opening
EventTile’s confirmation flow without a currentUserId. Preserve the existing
registration action for authenticated students.

Review comments at @frontend/src/Components/President/PresidentDashboard.jsx:
- Around line 21-24: Update the dashboard data-loading flow in
PresidentDashboard so each request failure is handled independently instead of
allowing one rejection to prevent all metric updates. Preserve successful
responses and update only the metrics associated with each successful request.

Review comments at @frontend/src/routes/AdminRoutes.js:
- Line 95: Pass an onSelectFeedback handler to ViewFeedback in the AdminRoutes
component so selecting a feedback card opens the selected feedback without
throwing. Reuse an existing selection handler or parent flow if available;
otherwise provide a handler that implements the route’s intended
feedback-opening behavior.

Coordinate certificate creation with the final state transition.

generateCertificates(batch) uploads PDFs and creates Approved certificate records before findOneAndUpdate confirms final approval. If that update fails or returns no batch, the handler reports 500 or 409, but those certificates remain. Claim the final-approval transition before generation, and define recovery for generation failure, so a failed approval cannot leave approved certificates attached to a submitted batch.

Use the coordinator’s contact email for the organizational-unit lookup.

If a coordinator’s username differs from their personal_info.email, this lookup returns 404 even when the unit’s contact_info.email matches the coordinator’s email. The user schema does not require those fields to match. backend/controllers/analyticsController.js already identifies the coordinator’s unit by personal_info.email. Use that same authenticated identity field here.

Pass the sandbox flags to the approval browser.

generateCertificates launches Puppeteer before passing the browser to renderToPdf, so the renderer does not apply PUPPETEER_NO_SANDBOX to that launch. If Chromium cannot use its sandbox, final approval can fail before PDF generation and leave the batch in Submitted state. Apply the same conditional launch arguments here.

🐛 Suggested fix
-    browser = await puppeteer.launch({ headless: true });
+    browser = await puppeteer.launch({
+      headless: true,
+      ...(process.env.PUPPETEER_NO_SANDBOX === "true"
+        ? { args: ["--no-sandbox", "--disable-setuid-sandbox"] }
+        : {}),

Base session-cookie settings on the backend transport.

If FRONTEND_URL uses HTTPS but a backend request arrives over HTTP, isHostedOverHttps sets cookie.secure to true. express-session then does not issue the session cookie, so login cannot persist. Determine backend HTTPS from the backend deployment or trusted request protocol. Require HTTPS for production rather than using the frontend URL as evidence of backend HTTPS. (github.com)

Handle Google routes when the strategy is disabled.

If either Google credential is absent, the /google and /google/verify routes in backend/routes/auth.js still call passport.authenticate("google"). Passport forwards an “Unknown authentication strategy” error instead of returning a deliberate disabled-service response. Gate those routes with the same configuration check, or return a controlled response when Google login is unavailable. (raw.githubusercontent.com)

Update the `/google` and `/google/verify` routes in `auth.js` to check for both
Google credentials before calling `passport.authenticate("google")`; when either
is absent, return a controlled disabled-service response instead of invoking an
unregistered strategy. Reuse the configuration check from `passportConfig.js`.

Discard results from a previous user ID.

When the user ID changes before fetchData() finishes, the earlier request can finish last and replace the current user's batches. Add effect cleanup or check the requested user ID before applying results. Clear the previous batch list when the identity changes.

Preserve an intentionally empty student selection.

If a user deselects all participants and saves, form.students becomes empty. On reopening the panel, this fallback selects every event participant again. Distinguish an untouched selection from a saved empty selection before applying the event default.

Give guests a working registration action.

When a logged-out visitor selects Register, EventTile opens the confirmation modal. Confirm then returns because currentUserId is absent, so the modal stays open without an explanation. Direct guests to login before confirmation, or replace Register with a sign-in action. The backend correctly requires authentication; the defect is the guest-facing action.

Review comment at @frontend/src/Components/Events/EventList.jsx at line 115:
Update the guest action in EventList’s userRole conditional so guests are
directed to sign in before registering, rather than opening EventTile’s
confirmation flow without a currentUserId. Preserve the existing registration
action for authenticated students.

Keep successful dashboard metrics when one request fails.

The endpoints return the expected response shapes. However, if any request rejects, Promise.all skips every metric update, and the catch block only logs the error. The dashboard can therefore retain its initial zero counts even when the other requests succeed. Handle each request failure separately.

Update the dashboard data-loading flow in PresidentDashboard so each request
failure is handled independently instead of allowing one rejection to prevent
all metric updates. Preserve successful responses and update only the metrics
associated with each successful request.

Pass a feedback selection handler to ViewFeedback.

When an admin selects a feedback card, ViewFeedback calls onSelectFeedback(fb). This route supplies no onSelectFeedback prop, so the action throws instead of opening the feedback. Pass a handler or render ViewFeedback through a parent that handles selection.

Pass an onSelectFeedback handler to ViewFeedback in the AdminRoutes component so
selecting a feedback card opens the selected feedback without throwing. Reuse an
existing selection handler or parent flow if available; otherwise provide a
handler that implements the route’s intended feedback-opening behavior.
