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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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(). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(mcp-oauth): literal SoD columns in the api_keys insert so the phantom-column scanner resolves them Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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.

feat(mcp): distribution polish for agent-first onboarding: CIMD, plugin start skill, bridge hint (#1814 PR 4) (#1866)
* feat(mcp): distribution polish for agent-first onboarding: CIMD, plugin start skill, bridge hint Fourth PR of agent-first onboarding (#1814). - The OAuth AS metadata advertises client_id_metadata_document_supported next to the existing `none` token auth, the pair Claude.ai, Claude Code and Codex look for to use CIMD instead of registering a DCR client per connection. authorize/token never keyed on client_id (the redirect-URI allowlist is the trust boundary), so nothing else changes; DCR stays for ChatGPT. - The plugin's start skill no longer sends a user without an account to the website: the /mcp OAuth screen creates the account, and a NO_COMPANY_YET briefing failure routes to the onboarding skill and accounted_create_company. README updated to match. - `npx accounted-mcp` without ACCOUNTED_API_KEY prints the OAuth alternative (Claude Code, Codex, Claude.ai connector) and that the account can be created on the sign-in screen; package README too. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018wCdzRTatKiDByKB8hCNT6 * fix(oauth): do not advertise CIMD until redirect URIs are matched against the client document CodeRabbit on #1866: advertising client_id_metadata_document_supported makes Claude and Codex send URL client_ids and expects an exact redirect_uri match against that document; the authorize endpoint only checks the global allowlist and never fetches client metadata. The flag is withheld until an SSRF-safe, cached CIMD fetch with exact redirect matching exists. DCR stays the registration path (stateless, so free).

feat(mcp): speak spec revision 2026-07-28 (stateless core) (#1277)
* feat(mcp): speak spec revision 2026-07-28 (stateless core) Adopt the 2026-07-28 MCP spec revision on the connector endpoint while keeping every handshake-era client (2025-06-18 and earlier) byte-identical: - Accept per-request _meta protocol negotiation (io.modelcontextprotocol/protocolVersion); unsupported versions return UnsupportedProtocolVersionError (-32022) with the supported list. - Implement server/discover (spec MUST): supported revisions, capabilities including the extensions field, identity, instructions, freshness hints. - Decorate results for stateless clients: required resultType, serverInfo in _meta, and CacheableResult ttlMs/cacheScope on tools/list, prompts/list, resources/list, resources/read. - Validate the standard Mcp-Method/Mcp-Name request headers when present (HeaderMismatchError -32020); absence stays accepted. - Declare the ratified MCP Apps extension (io.modelcontextprotocol/ui) in capabilities; the widgets already use the ratified mime type and _meta.ui.resourceUri shape, so no widget changes are needed. - OAuth: include the RFC 9207 iss parameter on every authorization response (success and error) and advertise authorization_response_iss_parameter_supported in RFC 8414 metadata. Resource-not-found already used -32602 and tools/list ordering was already deterministic; both are covered by the new test file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): Mcp-Name covers params.uri, base64 sentinel, version-header consistency Review follow-ups against the transport spec text: Mcp-Name mirrors params.name OR params.uri (resources/read), values arrive base64-wrapped in the =?base64?...?= sentinel and must be decoded before comparison, and an MCP-Protocol-Version header that disagrees with the _meta protocol version is a HeaderMismatch. Absence of any header stays accepted since this server supports handshake-era clients (spec-sanctioned leniency).

feat(domains): dual-domain cutover to app.accounted.se (#1087)
* feat(domains): dual-domain cutover to app.accounted.se The user-facing app moves to app.accounted.se while app.gnubok.se stays alive for machine traffic (MCP connectors, API keys, third-party OAuth callbacks, webhooks, crons), so no third-party callback registration is on the critical path. - next.config: host redirect app.gnubok.se -> NEXT_PUBLIC_APP_URL for page traffic only (/api, /.well-known, /_next excluded). Arms itself only once NEXT_PUBLIC_APP_URL leaves the legacy host, so merging this is inert and the cutover is a pure env flip + redeploy. - skatteverket: redirect_uri pinned via NEXT_PUBLIC_SKV_OAUTH_BASE_URL (Utvecklarportalen registration is slow to change); the OAuth callback now resolves the flow from the state token + stored oauth_user_id via the service client instead of session cookies, which no longer exist on the OAuth host. Legacy same-domain flows fall back to the session. - popup listeners (SkatteverketConnectPanel, AGIPanel) accept postMessage from the pinned OAuth origin; event.source identity check unchanged. - /.well-known discovery docs reflect the allowlisted request host so existing MCP connectors on app.gnubok.se keep a self-consistent issuer/resource after the flip; spoofed hosts fall back to canonical. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs: log dual-domain cutover decision Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(review): recency-bound SKV state lookup, exact localhost match in discovery allowlist - The oauth_state lookup now only considers rows updated in the last 10 minutes: bounds how long a leaked/phished authorize URL stays completable, keeps the row set far below PostgREST's 1000-row cap, and surfaces query errors instead of misreporting them as CSRF. - resolveDiscoveryBaseUrl matches localhost/127.0.0.1 exactly; the prefix check reflected spoofed hosts like localhost.evil.example.

style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests, and a few UI strings, reading as AI-generated boilerplate rather than house style. Replaced each with punctuation matching its context: colon for explanatory clauses, comma for asides, plain hyphen for numeric/legal ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for paired-dash asides. messages/en.json and messages/sv.json were fixed by hand together to keep sv/en in sync. Left untouched where the dash is the functional subject rather than decorative punctuation: date-range-parser.ts's separator regex, charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the agent system-prompt files that already instruct against em dashes, and a golden iXBRL test fixture compared byte-for-byte. Also fixes two bugs surfaced along the way: an off-by-one in ApiKeysPanel's scope-label split (a leftover from an earlier partial pass), and a charset-repair test that had lost the literal en-dash it exists to verify. Regenerated the agent atom seed migration (skills:generate) since 27 SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes, with an explicit carve-out for the functional-dash cases above. Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

feat: MCP server, API keys, OAuth, and KPI dashboard (#72)
* fix: prevent Chrome auto-translate from crashing React during onboarding
Chrome auto-translate modifies DOM text nodes when it detects a Swedish
page (lang="sv") in a browser set to English. React does not expect
external DOM mutations and throws, crashing the entire component tree
into global-error.tsx on every step transition.
Add translate="no" and <meta name="google" content="notranslate"> to
suppress browser translation. Also fix timezone-unsafe date parsing in
fiscal period validation (new Date("YYYY-MM-DD") + getDate() returns
local-timezone values, shifting dates by -1 day in Western timezones).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: add notranslate meta tag to global-error.tsx for consistency
Per review feedback — global-error.tsx renders its own <html> document,
so it needs the same <meta name="google" content="notranslate"> tag as
layout.tsx to fully suppress Chrome translation on error pages.

* feat: add MCP server extension with OAuth, API keys, and KPI dashboard
Let users do bookkeeping through Claude Desktop, Claude Code, or any
MCP-compatible client. "Show my uncategorized transactions." "Book that
as office supplies." "Invoice Acme for 15,000 kr."
MCP server (extension):
- 10 tools: transactions, categorization, customers, invoices,
trial balance, VAT report, KPI report, income statement
- JSON-RPC 2.0 protocol (no SDK dependency, works in serverless)
- Tool annotations, pagination, input validation per MCP best practices
- Same engine as web UI (VAT rules, exchange rates, event emission)
API key infrastructure (core):
- api_keys table with RLS, rate limiting (100 RPM), scopes column
- Atomic rate limit via DB RPC (validate_and_increment_api_key)
- Key management API routes + settings UI panel
OAuth 2.1 for Claude Desktop connectors:
- .well-known/oauth-protected-resource + oauth-authorization-server
- Authorization endpoint with consent page
- Token endpoint with PKCE verification
- Stateless encrypted auth codes (AES-256-GCM, no DB storage)
- Dynamic client registration
KPI dashboard:
- /nyckeltal page with hero cards, operational grid, trend chart
- GET /api/reports/kpi endpoint
- Gross margin, cash position, expense ratio, avg payment days,
VAT liability, revenue/expense trend
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address OAuth security vulnerabilities from code review
Critical fixes:
- Auth code replay: Track used codes in oauth_used_codes table with
unique constraint. Codes are single-use per OAuth 2.1 §4.1.2.
- Open redirect: Validate redirect_uri against hardcoded allowlist
of known Claude callback URLs + localhost for dev.
P1 fixes:
- Move API key creation from /authorize to /token endpoint. Keys are
only created after PKCE verification, preventing orphaned keys on
abandoned OAuth flows.
- Add ensureInitialized() to MCP server so event handlers load and
transaction.categorized events reach extensions.
P2 fixes:
- Remove 'plain' from PKCE methods — only S256 is advertised and
accepted.
- Fix extension count in sectors test (10 → 11 for mcp-server).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: remove duplicate ensureInitialized() that caused circular import
The extension router (ext/[...path]/route.ts) already calls
ensureInitialized() before dispatching to handlers. The duplicate
call in server.ts created a circular import that Turbopack couldn't
resolve, breaking the Vercel build.
