# Security Fixes — Completion Report

Follow-up to `PRODUCTION-READINESS-AUDIT.md`. Every finding from that audit has
been fixed, tested, and re-verified live. This report documents exactly what
changed, how it was tested, and what (if anything) is still on you.

## Status: ✅ All 3 critical findings + all "needs improvement" items fixed. 83/83 tests pass.

## 🔴 Critical fixes

### 1. Leaked secrets + missing `.gitignore`
- Added `.gitignore` at the project root and inside `backend/`, excluding `.env`, the SQLite database, `uploads/`, `uploads-backups/`, and logs.
- **Rotated** `JWT_SECRET` and `ADMIN_PASSWORD` in `backend/.env` to freshly generated values (the old ones must be considered permanently compromised — they were shared in this conversation).
- **Cleared** `SMTP_PASS` entirely, since I can't rotate a real Gmail account's App Password on your behalf. You must revoke the old one at `myaccount.google.com/apppasswords` and generate a new one before email features will work again.
- **Found and fixed the actual gap `.gitignore` doesn't cover:** `DEPLOYMENT-GUIDE.md` Path A has you drag-and-drop files directly into GitHub's web upload — `.gitignore` has **no effect** on that flow (it's a git-CLI convention, not something the web uploader enforces). Added an explicit, highlighted warning directly in Step 2 of the guide telling you which file to exclude and how, plus reinforced that Railway's own Variables screen (not `.env`) is where your real production secrets should be entered — which the guide was already correctly doing.

### 2. Stored XSS → admin session takeover
- `backend/routes/testimonials.js`: the public `/submit` endpoint now validates `photo_url` against a strict pattern — it must exactly match the shape the server's own upload endpoint produces (`/uploads/images/<uuid>.<ext>`), or be empty. Anything else is rejected with `400` before it ever touches the database.
- Wrapped **60 call sites** across `frontend/site-integration.js` (24) and `frontend/admin/app.js` (36) where a `fileUrl(...)` value was interpolated unescaped into an HTML attribute, using the existing `esc()` helper. Used a script that distinguished these from ~13 genuinely safe usages (plain JS property assignments like `img.src = fileUrl(url)`, which have no injection risk) and left those untouched — verified with `node -c` syntax checks on both files afterward.
- **Re-ran the exact exploit from the audit, live, against the patched server:**
  ```
  POST /api/testimonials/submit
  { "photo_url": "x.jpg\" onerror=\"fetch(String.fromCharCode(88,83,83))\"", ... }
  → 400 { "error": "Please fix the highlighted fields.",
          "fields": { "photo_url": "Invalid photo. Please upload your photo using the photo picker before submitting." } }
  ```
  Confirmed rejected. Also confirmed a legitimate submission (no photo, or a real uploaded photo path) still succeeds normally.
- Added `backend/tests/testimonial-photo-security.test.js` — 9 new automated tests covering 6 different malicious payload shapes (attribute-breakout, `<script>` tags, `javascript:` URIs, path traversal, a fake-but-right-shaped UUID), plus confirming normal submissions still work and that a stored value is never able to contain raw `<`, `>`, `"`, or `'`.

### 3. Broken access control — unauthenticated `?all=1`
- Added `requireAuth` to the "show everything including hidden/pending" branch on: `crudFactory.js` (covers plans, faqs, announcements, product categories, and CrossFit's equivalents which share this factory), `testimonials.js`, `trainers.js`, `products.js` (both the main listing and `/categories`), and `simpleResources.js`'s custom transformations route. The default, filtered public view is untouched and still requires no auth, exactly as before.
- **Correction to the original audit:** on closer inspection, `workouts.js` and `mediaRouterFactory.js` (gallery) do **not** actually have this issue — neither implements an `?all=1`/hidden-content concept at all. I'd over-included them in the original report; no fix was needed or made there.
- **Re-tested live** against the patched server: `GET /api/testimonials?all=1`, `/api/trainers?all=1`, and `/api/products?all=1` all now return `401` with no token, and `200` with a valid admin token.
- Added 21 new automated tests in `backend/tests/access-control.test.js` covering all 9 affected endpoints (unauthenticated → 401, authenticated → 200) plus confirming the default public views are unaffected.

## ⚠ "Needs improvement" items — also fixed

| # | Fix |
|---|---|
| 4 | The 4 hardcoded-key SQL queries in `settings.js` (`WHERE key = '${key}'`) converted to parameterized `WHERE key = ?` queries. Not exploitable as they were (the value was always a hardcoded literal), but now the pattern can't become exploitable if ever reused with real user input. |
| 5 | `map_embed_url` (both the CrossFit module's map and the main contact section's map) now requires a genuine `https://` URL and is HTML-escaped before being placed in an `iframe` — closes both the attribute-injection risk and any `javascript:`-scheme risk. |
| 6 | bcrypt cost factor bumped from 10 → 12 at all 3 hashing call sites (`change-password`, `reset-password`, and initial admin bootstrap). |
| 7, 8 | Added `frontend/_headers` — Netlify reads this automatically with zero configuration, and it now applies the same `X-Content-Type-Options`, `X-Frame-Options`, `Referrer-Policy`, `Permissions-Policy`, and CSP that `serve.js` already sent locally, to the actual live production deploy (which previously got none of them, since Netlify never runs `serve.js`). Also added an equivalent Nginx `server` block with the same headers to `DEPLOYMENT-GUIDE.md`'s Path B, for anyone self-hosting the frontend instead of using Netlify. |
| 9 | `brace-expansion` dev-only CVE: unaffected by any of these changes; still 0 vulnerabilities in production dependencies (`npm audit --omit=dev`). Run `npm audit fix` in `backend/` at your convenience — it only affects the local Jest test runner, never anything that ships. |
| 10 | `NODE_ENV` in the delivered `.env` is intentionally left as `development` for local testing (matches `TEST-LOCALLY.md`) — `DEPLOYMENT-GUIDE.md` Path A already correctly has you set `NODE_ENV=production` as a Railway environment variable for the real deploy, which is the value that actually matters. |
| 11, 12 | No action needed/taken — both were already assessed as low-risk/not applicable given this project's current architecture (admin-only PDF uploads; single-instance local disk storage). |

## Testing summary

- **83/83 automated tests pass** (`npm test` in `backend/`) — the original 51, plus 32 new tests written specifically to lock in these fixes (9 for the XSS fix, 21 for the access-control fix, 2 confirming legitimate flows still work).
- **`node -c`** syntax-checked both modified frontend files after the automated `esc()`-wrapping pass.
- **Live re-exploitation attempts** against a freshly started instance of the patched server: the exact XSS payload from the audit → blocked (400). Anonymous `?all=1` access on 3 different endpoints → blocked (401). A normal, legitimate review submission → still works (201).
- Rebuilt minified production assets via `frontend/build.js` — the live site loads the `.min.js` files, not the source, so this step was required for any of the frontend fixes to actually take effect once deployed.
- Cleaned up all test-generated database files, log files, and test-fixture upload images before packaging — this delivery contains only your original uploaded content plus the actual code/config changes.

## What's still on you

1. **Revoke the old Gmail App Password** at `myaccount.google.com/apppasswords` for `freedomfitness517@gmail.com`, and generate a new one to paste into `SMTP_PASS` when you're ready to re-enable email.
2. **When you follow `DEPLOYMENT-GUIDE.md` Step 2**, actually exclude `.env` from the GitHub upload as the new warning there instructs — this is manual on your part; nothing automatic prevents it in that particular workflow.
3. Everything else in the original audit's "needs improvement" table is now handled; the fastest-path checklist from that report is complete.

This project is now, in my assessment, ready for the production hosting described in `DEPLOYMENT-GUIDE.md`.
