Jakob Wennberg 18cbc4c30a fix(security): audit remediation 2026-09-01: api_keys identity, viewer gates, OAuth binding, XSS, MFA gate (#2155)
* fix(security): bind api_keys to the caller, lock hash-as-bearer RPCs and provider token tables

Security audit 2026-09-01, critical items.

- api_keys INSERT requires user_id = auth.uid() again (an admin could
  forge a key for any co-member and act as them in every company they
  belong to); SELECT is own-keys-or-admin; a BEFORE trigger freezes the
  identity and credential columns against user-session UPDATEs.
- rotate_mcp_refresh_token and validate_and_increment_api_key become
  service_role only: they match rows by a presented SHA-256, so a hash
  readable by co-members was a bearer credential.
- validate_and_increment_api_key fails closed when the key's user is no
  longer a member of the key's company.
- provider_consent_tokens and provider_otc: the DELETE policies collapsed
  to "caller has any team row" (correlated subquery on a non-existent
  team_members.company_id). All member policies dropped; service_role
  only, matching every existing code path.

* fix(security): role gates, ownership guards and posting integrity in the database

Security audit 2026-09-01, high items at the database layer.

- One table-level guard, enforce_company_writer_role(), blocks the
  read-only viewer role on 55 company-scoped tables including through
  the 15 membership-only SECURITY DEFINER writers. Keyed on the JWT role
  claim so it fires inside definer bodies; no-op for service_role and
  trigger cascades.
- company_members user_id/company_id immutable from user sessions;
  invitations can never grant owner; team_members gains a transition
  guard (admins keep non-owner role moves); companies team_id and
  archiving are owner-only and team attachment needs team membership.
- Direct statements (current_user = authenticated) can no longer insert
  posted headers, add lines under posted verifikat, or post a draft with
  a voucher number the sequence never issued. Sanctioned RPCs run as the
  definer and are untouched; the engine's own draft-then-post shapes
  still pass.
- create_document_version refuses viewers and foreign storage paths;
  validate_version_chain needs membership and loses anon EXECUTE;
  match_documents / match_booking_templates lose anon; cron maintenance
  RPCs become service_role only; the production-only
  seed_asset_categories is dropped.

* build: pin tsx as an exact devDependency instead of fetching it with npx at build time

prebuild ran "npx tsx" with no lockfile entry, so every Vercel, Docker
and CI build downloaded tsx@latest and its transitive tree from the
registry with no integrity check, inside the build environment.

* fix(security): refuse the viewer role on API-key and MCP write paths

The v1 wrapper and the MCP company routing checked company membership
but never role, and both run as service role, so a read-only viewer
holding an API key could post vouchers and change settings through the
API. Mutating methods and non-read scopes now return 403 ROLE_READ_ONLY
for viewers on v1; MCP write tools refuse viewers the same way.

* fix(security): stop serving uploaded SVG, XML and HTML as executable content on the app origin

Uploads persisted the browser-declared mime type and the inline proxy
served it verbatim, sandboxing only text/html; the storage proxy
forwarded the uploader's Content-Type. Any writer, or any Peppol sender,
could plant a scripted SVG or XHTML that executed on app.gnubok.se.

- inline route: allow-list of natively safe types (PDF, raster images)
  served as before; everything else gets the opaque sandbox CSP.
- storage proxy: octet-stream + attachment + sandbox unless the DB
  mime for the key is on the allow-list.
- document-service: the stored mime is the magic-byte validated type.
- logo upload: magic-byte validation, SVG refused.

* fix(security): byrå brand logo upload decides the type by magic bytes and drops SVG

Same pattern as the company logo route: the logos bucket is public, so a
scripted SVG (or anything declared as an image) must never land there.
The upload pickers stop advertising SVG.

* fix(security): bind Enable Banking, Stripe and WooCommerce callbacks to the initiating user

The callbacks resolved the pending row by oauth_state alone, so a
victim who completed an attacker-initiated consent had their bank
account, merchant account or store attached to the attacker's company.
requireFlowInitiator() now requires the cookie session of the user who
started the flow: no session redirects to login with the callback URL
preserved, a different user is refused and nothing is exchanged.

* fix(security): guard tenant-controlled outbound fetches and surface the disabled rate limiter

WooCommerce and Shopify syncs fetched a member-editable store URL with
plain fetch() and redirect following under the service role, and the
invoice PDF renderer fetched company_settings.logo_url unguarded. All
three go through a new safeFetch() (public-IP validation via url-guard,
https only, redirect: 'manual', body size cap) and re-normalise the
stored host at use time. checkRateLimit() keeps failing open on hosted
but logs one error per process when Upstash is not configured and
exports isRateLimiterConfigured().

* fix(security): decide the API MFA gate from server-authenticated factors, not the session cookie

getAuthenticatorAssuranceLevel() without arguments derives nextLevel
from session.user.factors, which comes from the unsigned sb-*-auth-token
cookie. Deleting factors from the cookie made an enrolled account look
like it had nothing to step up to, on every /api route and in
requireAuth. Both gates now read factors from the getUser() result or
listFactors() and the level from the verified JWT claim, and fail closed
on errors. Page-branch gate hardened the same way.

* fix(security): bind Fortnox/Visma, Gmail and Skatteverket callbacks to the initiating user

The arcim-migration callback exchanged the provider code onto whatever
consent the one-time state named, with no check of who completed the
flow and no org-number comparison, so a phished Fortnox admin handed
their ledger to the attacker's company. provider_otc now records the
initiating user (migration 20260902100000); the callback requires that
session and, after the exchange, refuses a provider company whose org
number differs from the consent's company. The Gmail and Skatteverket
callbacks enforce the same initiator check.

* fix(security): BankID signup confirms the email before linking the identity

Signup created an email-confirmed, MFA-exempt account for any address
the caller typed and returned a magic link, so an attacker could
pre-register a victim's email and keep a permanent BankID login into the
account the victim later adopted. The user is now created unconfirmed,
the identity carries email_verified_at NULL (migration 20260902101000),
bankid_linked is not set until the mailed confirmation is clicked, and
BankID login of a pending identity is refused with the confirmation
re-sent.

* fix(security): bind MCP OAuth redirect URIs to the consenting user and cap scopes

A user-registered redirect URI was allowlisted globally, the consent page
named no client, and all scopes were pre-checked, so one phishing link
handed an attacker a full-scope key for the victim's company. Registered
URIs now resolve only for the registrant or a colleague sharing a
company; the consent page shows the client identity and redirect host;
non-built-in clients default to read-only pre-checks; scopes are capped
by the user's role (viewer: read only) at consent and at /token.

* fix(auth): client follow-ups for BankID confirmation, callback mismatch copy and decision log

- register client handles the new confirmation_sent response from BankID
  signup with the existing inbox screen instead of calling verifyOtp.
- BankID login surfaces the email_unconfirmed explanation.
- WooCommerce settings map woocommerce_error=wrong_user to its own copy.
- Logo help text no longer advertises SVG.
- DECISIONS.md records the audit remediation choices.

* fix(mcp-oauth): literal SoD columns in the api_keys insert so the phantom-column scanner resolves them

* test(logo): type the upload fixtures as Uint8Array<ArrayBuffer> so they are valid BlobParts

Fixes the typecheck ratchet on PR #2155 and ratchets the baseline down
by the one legacy error the change removed.

Mattsson d54b43f80f Bug/resend and invoices (#1192)
* fix(invoices): anchor the PDF logo to the top-left of its header cell

The logo box is always the full 240x80pt reserved area (any larger logo is
clamped to exactly that), so objectFit: 'contain' placed the image inside it
with the default 50% 50% centering. A wide banner logo fills the width and
lands on the left margin, but a near-square logo scaled down to the 80pt
height cap is only ~117pt wide and got pushed ~60pt in from the margin, which
reads as a misaligned logo and forced companies to reshape their artwork.

Anchor the image top-left so every aspect ratio starts at the margin.

Covered by a test that renders the real PDF and reads the image placement
matrix out of the content stream, for both a wide and a near-square logo.

* feat(invoices): show the real delivery outcome in the send history

"Skickad" only meant the email provider accepted the message, so a bounced
invoice looked identical to one that arrived. Resend reports the outcome
asynchronously; that report now lands on the delivery row and drives the
history: green is reserved for a confirmed delivery, bounce/blocked reads
red, delayed and spam-marked read amber, and an accepted-but-unconfirmed
send is neutral instead of falsely green.

The report arrives on a signed webhook and may only touch the three new
provider status columns of an already sent, unredacted row: the WORM trigger
proves nothing else changed, and a lower ranked or older report can never
downgrade an observed failure. The provider reason text can quote the failing
address, so it is masked on read and cleared by the daily PII redaction job.

Timestamps also formatted in Europe/Stockholm instead of falling back to the
runtime zone, which rendered a 14:05 send as 12:05 on Vercel.

Delivery reports are per message, never per recipient: Resend sends one event
for the whole message, so splitting a send per recipient would be the only way
to get finer granularity, at the cost of CC.

* feat(stripe): make the integration feed-only

Stripe sync now only imports balance transactions into the transactions
inbox, like any bank feed; nothing auto-books. The event/settlement sync
(lib/sync.ts, lib/payouts.ts) stays in the repo but is no longer wired to
any route or cron: the 15-min sync cron is removed from vercel.json.
Payment links on invoice send are unchanged; their payments arrive as
feed rows and are matched manually.

- /sync runs only syncStripeBalanceTransactions; response is { success,
  transactions }
- connecting via OAuth enables the nightly feed by default (toggle stays
  as opt-out)
- panel: needs-review section and plumbing removed, copy rewritten to
  transactions-first (sv + en), toast reports fetched/imported/linked
  and calls out an empty result instead of silent all-zeros

* fix(api): return the article currency from the v1 article list

The dashboard, importer, export and MCP article surfaces all learned to
carry a non-SEK article price (#1166, #1183, #1184), but the v1
projection still omitted currency. An API or agent caller therefore read
price_excl_vat with nothing marking it as EUR and would copy the number
straight onto a SEK invoice line, at a nine-to-one error.

Adds currency to the projection, the response shape and the example, plus
a pitfall stating the price is not always SEK and that this endpoint does
no FX conversion.

Additive field only; no migration (articles.currency already exists).

* feat(settings): replace the settings modal with a routed panel sheet

Settings now renders as a sheet that fills the main panel, sliding up over the
page the user came from and back down on close, with the sidebar and frame left
visible and usable. Behind it sits one shared master-detail surface: underline
search across every section and subsection, the grouped section rail, and the
active section as a direct-editing accordion. All 11 sections are decomposed
into subsections, and the legacy *SettingsContent components compose the same
pieces so the stacked and accordion layouts cannot drift.

The sheet is the only presentation, on every entry path. The intercepting route
handles in-app navigation and closes by popping the history entry, landing back
on the page underneath. @settingsModal/default.tsx handles cold loads (refresh,
deep link, new tab), where interception never fires; nothing is mounted
underneath there, so it closes to the dashboard. Both branch on one shared
predicate, isSheetSection, together with the settings layout, which must render
nothing for those sections or the surface would stack twice behind the sheet
and run every section's fetches twice.

Closing is deliberate rather than incidental: the X, Esc, or navigating away.
The dialog is non-modal so the sidebar's account popover and company switcher
keep working with settings up, and an outside click no longer dismisses it.
Sections land fully collapsed, and the scroll position of the page behind
survives opening and closing the sheet.

* feat: enhance article management and settings UI

- Add PATCH test for toggling article active state without other fields.
- Remove unused MessageCircle icon from DashboardContent.
- Refactor AccountingFrameworkForm to use SettingsFieldRow for better help text display.
- Update CompanyInfoForm, DimensionsToggle, and various settings forms to replace description with help text.
- Remove redundant headings and intros in several settings components to streamline UI.
- Improve help text for various settings in English and Swedish translations.
- Update structured error messages for better clarity on article deletion.

* refactor(ArticleDetailPage): remove unused imports and duplicate state variable

* fix(settings): own deep-linked settings routes by route list, not nav visibility

Review fixes from the settings panel sheet work:
* isSheetSection reads the full settings route list so a hidden-but-deep-linked
  section (assistant before BankID, banking in sandbox, api without MCP) is
  claimed by the sheet instead of rendering the legacy shell around an empty panel
* keep 503 on the Resend delivery webhook when the signing secret is unset, with
  a test pinning the behaviour
* stripe callback route test coverage
