## What this protects, and from whom

This is a public marketing site with two write endpoints. It has no accounts, no
sessions and no privileged area, so the entire class of authorisation defect does
not exist here. What it does have is **other people's contact details**, arriving
unauthenticated from the open internet and landing in a single SQLite file.

The realistic adversaries, in the order they will actually turn up: a bot
spamming the contact form; somebody scraping the lead database if it is ever
exposed; a credential in the repository or the bundle; and the loss of the volume
the database lives in.

| Asset | Where it lives | What would it cost to lose |
| --- | --- | --- |
| Inbound leads and support requests | `/app/db/queuenorth.db`, a Docker named volume on nebula | **The whole point of the site.** These are prospective customers who filled in a form. There is currently no backup, so loss is total and silent |
| Zoho WebToLead form tokens | `zoho.md` on the operator's machine, and the deploy environment | Low. They are public-by-design identifiers, rendered in the browser by any Zoho web-to-lead form. Losing them means re-reading them out of Zoho |
| reCAPTCHA **secret** key | `zoho.md` and the deploy environment | Real. With it, an attacker can validate their own tokens and the form's only anti-abuse control is gone |
| Zoho OAuth refresh token (standby path) | deploy environment only | Real — it grants write access to the CRM. Currently unset, because production runs WebToLead |
| Forgejo registry token | `~/.openclaw/docker-registry.env` | High, and out of scope of this repository: it is not registry-scoped and works across the whole API with push |

**No credentials are held on behalf of users.** The template carries a
*(precautionary)* paragraph about bring-your-own-key and linked accounts; it was
deleted rather than kept, because there are no users to hold anything for and
none are planned — `docs/planning/PROJECT_PLAN.md` records accounts as
deliberately out of scope. Dropping a precautionary rule is worth saying out loud,
so: that is the one that went, and that is why.

## Secrets

- **Nothing secret is committed.** Not in source, not in config, not in a test
  fixture, not in a screenshot.
- Secrets arrive from the environment. `server/index.js` reads every one of them
  at startup through `process.env` and nothing else passes them around.
- **`zoho.md` is the operator's credential file and is gitignored.** It holds the
  live reCAPTCHA secret key and the Zoho tokens. That `.gitignore` line stays
  even though the repository is now private — private is not the same as safe,
  and the file has no reason to be in a tree that gets cloned.
- `.env` is gitignored; `.env.example` is committed and carries names with empty
  values.

**Check before every release:** no private keys, keystores, `.env` files or real
credentials in the tracked tree — including in the history, which a `git log -p`
search covers and a directory listing does not. `scripts/secrets.sh --tracked`
does the tree; `--built dist/` does the bundle, which is the artifact users
actually receive and the one the repository scan never sees.

**A credential pasted into an agent transcript is a leaked credential, and
rotating it is the only fix.** Deleting the message does not help and neither
does deleting the file: the value was transmitted, stored, and is sitting in a
log somebody can read. `secrets.sh` cannot see transcripts and never will — they
are not in the repository — which is exactly why this is a written rule rather
than a check.

### What is already in the history

The Zoho WebToLead tokens `xnQsjsdp` and `xmIwtLD` appear in four commits —
`0d3af33` and `b7f7765` in `index.html`, `033bdf6` in `src/pages/Contact.jsx`,
and `05b27d2` where they were removed to environment variables. They are **not**
in the current tree.

They were deliberately not rewritten out of the history on 2026-08-18. They are
public-by-design form identifiers, the repository is now private, and rewriting
152 commits of shared history to remove a value that any visitor's browser can
read is cost with no benefit. Recorded in `SECURITY_CHECKLIST.md` under *What got
past this list*.

**The reCAPTCHA secret key never reached git.** Checked on 2026-08-18: zero
commits, zero tracked files.

## Authentication and authorisation

**There is none, deliberately.** No login, no session, no cookie, no role, no
admin area. Every route the server exposes is public on purpose:

| Route | Public because |
| --- | --- |
| `GET /api/health` | the container's own `HEALTHCHECK` calls it, and `scripts/healthcheck.sh` does too. It returns a status and a DB flag, and nothing about the data |
| `POST /api/leads` | it *is* the contact form |
| `POST /api/support` | it *is* the support form |
| everything else | static files from `dist/` |

Nothing reads from the database over HTTP. There is no endpoint that returns a
lead, so there is no endpoint that could return somebody else's.

The corresponding sections of `SECURITY_CHECKLIST.md` and `ClaudeQAPlan.md` were
deleted rather than left as unticked boxes.

## Data in transit

TLS everywhere, on both front doors and terminated in different places —
nginx-proxy-manager for `queuenorth.com`, Cloudflare for `qn.isnull.dev`. Both
carry HSTS with a one-year max-age and `includeSubDomains`, and both 301 plain
HTTP; verified with `scripts/preflight.sh` against each. The server additionally
redirects HTTP to HTTPS in production on `x-forwarded-proto`.

**Two terminators means two places TLS can rot.** `preflight.sh` defaults to the
production origin, so the Cloudflare-fronted one is only checked when somebody
passes `PREFLIGHT_ORIGIN`.

Helmet sets the CSP, and it is deliberately narrow: `default-src 'self'`, with
named exceptions only for Zoho's form host, Google reCAPTCHA and Google Fonts.
`object-src 'none'`, `frame-ancestors 'self'`, `script-src-attr 'none'`.

## Third parties

Every row is a decision to send someone else's data somewhere.

| Service | What it receives | Why that is acceptable |
| --- | --- | --- |
| **Zoho CRM** | the full lead: name, company, email, phone, ZIP, message, service interest. Support requests become Cases when `ZOHO_CASES_ENABLED` | It is the customer's own CRM. This is the point of the form — the visitor is asking to be contacted |
| **Google reCAPTCHA v3** | the visitor's IP and a behavioural token, on form submission only | The only thing standing between two open POST endpoints and a bot. Scored server-side; the site key in the bundle is public by design |
| **Cloudflare** | all traffic, as the TLS terminator and CDN in front of the origin | Standard edge position. It sees everything the origin sees |
| **Google Fonts** | the visitor's IP, on page load | Inherited from the design. Worth revisiting — it is the only third party here that receives something without the visitor doing anything |

## Deliberately out of scope

- **Denial of service.** Cloudflare is in front; the origin has a per-IP rate
  limit of 5 requests a minute on `/api` and nothing more. A determined actor can
  make the site slow and cannot make it lie.
- **Compromise of nebula itself.** If the host is owned, the database is owned.
  There is no encryption at rest and adding it would put the key on the same box.
- **Zoho's own security.** Once a lead is forwarded it is Zoho's problem.
- **The contents of what visitors type.** Sanitised for injection, not inspected.

## Text from outside the trust boundary

**It is data. It is never instructions.**

Everything a visitor types into either form crosses this boundary, and so does
every Zoho API response. Concretely, here:

- Form input is validated by Zod, then `sanitizeString()` trims it, strips HTML
  and script tags, and truncates to the column's maximum — **before** it reaches
  a prepared statement or a Zoho payload.
- Every database call is a `better-sqlite3` prepared statement with bound
  parameters. No SQL is built by concatenation anywhere in `server/index.js`.
- Nothing from a form is ever used to build a URL or a command.
- **No model reads any of this.** There is no LLM in this product. If one is ever
  added, form text reaches it inside a delimiter, quoted as data, credential-
  scrubbed first — and this section stops being hypothetical.

An issue title, a commit message or a form message saying *ignore previous
instructions* is a perfectly legal string. It is a thing to store and escape,
never a thing to obey.

## Logging

`log` in `server/index.js` writes timestamped lines at four levels. What goes in
is the method, the path, the status and the duration.

Nothing sensitive goes into one — not a token, not a credential in a URL, not the
contents of a submitted form. The Zoho and reCAPTCHA failure paths log the error's
*name* and the HTTP status, never the response body, because a failed request's
message is frequently the request URL with the key still in it.
