However, **adoption of this middleware is inconsistent** — roughly 40% of routes bypass it entirely by using raw `getServerSession()` calls, creating security gaps. The most critical findings are: + +1. **Inconsistent middleware adoption** — many routes skip the `apiHandler` wrapper and lose CSRF, content-type, and body-size protections. +2. **Missing rate limiting on most routes** — only 2 out of 50+ routes apply rate limits. +3. **Several routes lack multi-tenant store isolation** — particularly checkout, payment config, and subscription routes. +4. **Verbose production logging** — numerous `console.log` calls leak internal state and debug data. +5. **Permission checks missing on customer POST** — the customer create endpoint checks `customers:create` permission but does not verify storeId access. + +--- + +## 1. Auth Group (`/api/auth/`) + +### Files Reviewed +- `signup/route.ts` +- `verify-email/route.ts` + +### Findings + +| Check | signup | verify-email | +|-------|--------|--------------| +| Authentication | ✅ Correctly skipped (`skipAuth: true`) | ✅ N/A (public) | +| Input Validation (Zod) | ✅ Comprehensive schema | ✅ Token validated | +| Rate Limiting | ✅ `authRateLimit` applied | ❌ **MISSING** | +| Error Handling | ✅ Zod + catch-all | ✅ Try/catch with redirect | +| CSRF | ✅ Skipped via `apiHandler` for public route | N/A (GET only) | +| Response Format | ✅ Consistent JSON | ✅ Redirect-based | + +### Issues + +- **MEDIUM — `verify-email` has no rate limiting.** An attacker could brute-force token guesses against the endpoint. The token is 32 random bytes (extremely hard to guess), but rate limiting is still best practice to prevent abuse. +- **LOW — Enumeration-safe response in signup.** Good: when a user already exists, the signup returns `200` with a generic message (no user enumeration). However, the response structure differs from the new-user path (`success: true` with `message` vs. the same), which is acceptable. +- **INFO — `verify-email` uses GET for state change.** The verification link triggers user creation, organization setup, and store provisioning via a GET request. This is standard for email verification flows, but the endpoint does a lot of heavy writes (create user, org, membership, store, subscription, notifications). If the link is pre-fetched by an email security scanner, these side effects fire. Consider a two-step flow (GET renders a confirmation page, POST commits). + +--- + +## 2. Admin Group (`/api/admin/`) + +### Files Reviewed +- `users/route.ts` +- `stores/route.ts` +- `subscriptions/route.ts` + +### Findings + +| Check | admin/users | admin/stores | admin/subscriptions | +|-------|-------------|--------------|---------------------| +| Authentication | ✅ `apiHandler` | ✅ `apiHandler` | ✅ Manual `requireSuperAdmin` | +| SuperAdmin Check | ✅ Double-checked (permission + DB lookup) | ⚠️ Relies on permission `admin:stores:read` only | ✅ Direct DB check | +| Input Validation | ✅ Zod + sanitizer | ⚠️ Raw `search` param unsanitized | ✅ `z.discriminatedUnion` | +| Rate Limiting | ✅ `searchRateLimit` | ❌ **MISSING** | ❌ **MISSING** | +| CSRF | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ❌ **MISSING** (raw handler) | +| Error Handling | ✅ | ✅ | ✅ Try/catch | +| Response Format | ✅ `createSuccessResponse` | ✅ `createSuccessResponse` | ⚠️ Raw `NextResponse.json` | + +### Issues + +- **HIGH — `admin/subscriptions` bypasses `apiHandler`.** Both GET and POST export raw `async function` handlers instead of using `apiHandler`. This means: + - No CSRF protection on the POST endpoint (subscription extend/suspend/upgrade). + - No content-type validation. + - No body-size limit enforcement. + - No centralized error handling wrapper. +- **MEDIUM — `admin/stores` does not sanitize the `search` parameter.** Unlike `admin/users` (which uses `sanitizeSearchInput`), the stores route passes raw user input directly to a Prisma `contains` query. While Prisma parameterizes queries (preventing SQL injection), this is an inconsistency. +- **LOW — `admin/subscriptions` has inconsistent response format.** Uses raw `NextResponse.json()` instead of the `createSuccessResponse`/`createErrorResponse` helpers. + +--- + +## 3. Products Group (`/api/products/`) + +### Files Reviewed +- `route.ts` (GET/POST) +- `[id]/route.ts` (GET/PATCH/DELETE/PUT) +- `bulk/route.ts` (POST) +- `import/route.ts` (POST) +- `export/route.ts` (GET) + +### Findings + +| Check | products/ | products/[id] | bulk | import | export | +|-------|-----------|---------------|------|--------|--------| +| Authentication | ✅ `apiHandler` | ✅ `apiHandler` | ✅ Manual session | ✅ `apiHandler` | ✅ Manual session | +| Permission | ✅ `products:read/create` | ✅ Per-method | ⚠️ None specified | ✅ `products:create` | ⚠️ None specified | +| Store Isolation | ✅ `requireStore` + tenant resolver | ✅ `verifyStoreAccess` | ✅ `getAuthorizedStoreId` | ✅ `verifyStoreAccess` | ✅ `getAuthorizedStoreId` | +| Input Validation | ✅ Zod in service | ✅ `cuidSchema` | ✅ `createProductSchema` | ✅ CSV + Zod | N/A (read-only) | +| CSRF | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ❌ **MISSING** | ✅ Via `apiHandler` | N/A (GET) | +| Rate Limiting | ❌ | ❌ | ❌ | ❌ | ❌ | +| Error Handling | ✅ | ✅ | ✅ | ✅ | ✅ | + +### Issues + +- **HIGH — `products/bulk` bypasses `apiHandler`.** The bulk create endpoint uses raw `getServerSession` and `getAuthorizedStoreId` manually. It loses CSRF protection, content-type validation, and body-size limits. For a bulk operation accepting up to 100 products, body-size enforcement is important. +- **HIGH — `products/bulk` has no explicit permission check.** Unlike the main route (which requires `products:create`), the bulk route only checks authentication and store access. Any authenticated user with store access can bulk-create products regardless of their role permissions. +- **MEDIUM — `products/export` bypasses `apiHandler`.** Uses manual session check. Missing CSRF (though GET is safe), but more importantly, has no explicit permission check string — it manually validates session and store but doesn't use `checkPermission('products:read')`. +- **LOW — `products/[id]` PATCH has verbose console.log statements.** Lines 57-60 and 67-68 log storeId, variant counts, and access decisions. These should be removed or use a structured logger with level control. +- **LOW — `products/import` accepts `formData`, but `apiHandler` enforces `Content-Type: application/json`.** The `withApiMiddleware` function rejects non-JSON content types for POST/PUT/PATCH. The import route uses `apiHandler` with `permission: 'products:create'`, which means the middleware will reject the multipart form-data upload with a 415 error. This is a **functional bug** — the import route is likely broken in production unless the CSRF/content-type check is bypassed. + +--- + +## 4. Orders Group (`/api/orders/`) + +### Files Reviewed +- `route.ts` (GET/POST) +- `[id]/route.ts` (GET/PATCH/DELETE) +- `[id]/status/route.ts` (PATCH) +- `[id]/cancel/route.ts` (POST) +- `[id]/refund/route.ts` (POST) + +### Findings + +| Check | orders/ | orders/[id] | status | cancel | refund | +|-------|---------|-------------|--------|--------|--------| +| Authentication | ✅ Manual | ✅ Manual | ✅ `apiHandler` | ✅ `apiHandler` | ✅ `apiHandler` | +| Permission | ✅ `checkPermission` | ✅ Per-method | ✅ `orders:update` | ✅ `orders:update` | ✅ `orders:update` | +| Store Isolation | ✅ `hasStoreAccess` | ✅ `hasStoreAccess` | ✅ `hasStoreAccess` | ✅ `hasStoreAccess` | ✅ `hasStoreAccess` | +| Input Validation | ✅ Zod schemas | ⚠️ Partial | ✅ Zod | ✅ Zod | ✅ Zod | +| CSRF | ❌ **MISSING** | ❌ **MISSING** | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ✅ Via `apiHandler` | +| Rate Limiting | ❌ | ❌ | ❌ | ❌ | ❌ | + +### Issues + +- **HIGH — `orders/route.ts` (GET/POST) bypasses `apiHandler`.** Both the list and create handlers are raw `async function` exports. They lack CSRF protection, content-type validation, and body-size limits on the POST handler. +- **HIGH — `orders/[id]/route.ts` (PATCH/DELETE) bypasses `apiHandler`.** The PATCH endpoint accepts storeId from the request body without the middleware's protections. +- **MEDIUM — `orders/[id]` GET allows unauthenticated access.** The route has a dual-path: authenticated users need session + store access, but unauthenticated users can view orders by providing a matching email or phone. While this is intentional for post-checkout flows, the unauthenticated path: + - Passes an empty string as storeId when storeId is null (`storeId || ''`), which may return orders from any store. + - Does not rate-limit guessing attempts on order IDs with emails. +- **MEDIUM — `orders/[id]` PATCH has excessive `console.log` statements.** Lines 136, 148-149, 179, 189-195, and 225 log session user IDs, full request bodies, and order data. +- **LOW — `orders/` GET checks permission before checking session.** The `checkPermission` call implicitly gets the session, but the explicit session check on line 62 happens after. If the permission check succeeds, the session is guaranteed. However, the error ordering is inverted — a 403 fires before a potential 401. +- **LOW — Order POST gets storeId from `x-store-id` header.** This is an unusual pattern compared to the rest of the codebase (query params or body). It's functional but inconsistent. + +--- + +## 5. Customers Group (`/api/customers/`) + +### Files Reviewed +- `route.ts` (GET/POST) +- `export/route.ts` (GET) +- `bulk/route.ts` (POST) + +### Findings + +| Check | customers/ | export | bulk | +|-------|-----------|--------|------| +| Authentication | ✅ `apiHandler` | ✅ `apiHandler` | ✅ Manual | +| Permission | ✅ `customers:read/create` | ✅ `customers:read` | ⚠️ None specified | +| Store Isolation | ✅ GET uses `requireStore` | ⚠️ Permission only, no store access check | ✅ `getAuthorizedStoreId` | +| CSRF | ✅ Via `apiHandler` | N/A (GET) | ❌ **MISSING** | +| Rate Limiting | ❌ | ❌ | ❌ | + +### Issues + +- **HIGH — `customers/bulk` bypasses `apiHandler`.** Same pattern as products/bulk: manual session check, no CSRF, no content-type validation, no body-size limit, and **no explicit permission check** for `customers:create`. +- **MEDIUM — `customers/` POST does not verify store access.** The create customer handler has `permission: 'customers:create'` but does NOT use `requireStore: true`. The `storeId` comes from the request body and is passed directly to the service without verifying the user has access to that store. Any authenticated user with the `customers:create` permission could create customers in any store. +- **MEDIUM — `customers/export` has no store access verification.** The route validates the storeId format with Zod but does not call `verifyStoreAccess` or use `requireStore`. It queries all customers for the given storeId if the user has `customers:read` permission, potentially leaking customer data from other tenants. + +--- + +## 6. Checkout Group (`/api/checkout/`) + +### Files Reviewed +- `complete/route.ts` (POST) +- `validate/route.ts` (POST) +- `shipping/route.ts` (POST) +- `payment-intent/route.ts` (POST) + +### Findings + +| Check | complete | validate | shipping | payment-intent | +|-------|----------|----------|----------|----------------| +| Authentication | ✅ `apiHandler` | ✅ `apiHandler` | ✅ `apiHandler` | ✅ `apiHandler` | +| Permission | ⚠️ `checkout:complete` | ⚠️ `checkout:validate` | ⚠️ `checkout:shipping` | ⚠️ `checkout:payment` | +| Store Isolation | ⚠️ Via service (storeId in body) | ⚠️ Via service | ⚠️ Via service | ✅ Order-store verification | +| Input Validation | ✅ Zod | ✅ Zod | ✅ Zod | ✅ Zod | +| CSRF | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ✅ Via `apiHandler` | + +### Issues + +- **MEDIUM — Checkout routes require authentication but should likely be public.** All checkout routes require authentication through `apiHandler({})`. However, the permissions used (`checkout:complete`, `checkout:validate`, etc.) appear to be custom permissions that may not be assigned to all user roles. If storefront customers are not authenticated users, the checkout flow is broken for guest checkout. +- **MEDIUM — No explicit store access verification in checkout routes.** The `storeId` is accepted in the request body and passed to the checkout service without verifying the authenticated user has access to that store. The service may perform its own checks, but the API layer should enforce this. +- **LOW — `payment-intent` returns mock/placeholder data.** The endpoint returns fake Stripe payment intent data with `pi_mock_*` identifiers. This is documented with TODO comments but should not be deployed to production. + +--- + +## 7. Subscriptions Group (`/api/subscriptions/`) + +### Files Reviewed +- `subscribe/route.ts` (POST) +- `cancel/route.ts` (PATCH) +- `upgrade/route.ts` (POST) +- `downgrade/route.ts` (POST) + +### Findings + +| Check | subscribe | cancel | upgrade | downgrade | +|-------|-----------|--------|---------|-----------| +| Authentication | ✅ `apiHandler` | ✅ Manual | ✅ Manual | ✅ Manual | +| Permission | ❌ **NONE** (empty `{}`) | N/A (self-service) | N/A (self-service) | N/A (self-service) | +| Store Isolation | ❌ **MISSING** | ✅ `getCurrentStoreId` | ✅ `getCurrentStoreId` | ✅ `getCurrentStoreId` | +| Input Validation | ✅ Zod | ✅ Zod | ✅ Zod | ✅ Zod | +| CSRF | ✅ Via `apiHandler` | ❌ **MISSING** | ❌ **MISSING** | ❌ **MISSING** | +| Rate Limiting | ❌ | ❌ | ❌ | ❌ | + +### Issues + +- **HIGH — `subscribe` has no permission check and no store context.** The handler is wrapped with `apiHandler({})` — empty options means auth is required but no permission is checked. It accepts a `customerId` in the body with no verification that the customer belongs to the user's store. Additionally, this returns mock data. +- **HIGH — `cancel`, `upgrade`, `downgrade` bypass `apiHandler`.** All three export raw handlers, losing CSRF protection. These are financial operations where CSRF attacks could lead to unauthorized plan changes. +- **MEDIUM — No rate limiting on subscription operations.** An attacker could repeatedly trigger upgrade payment flows, potentially causing SSLCommerz session flooding. + +--- + +## 8. Payments Group (`/api/payments/`) + +### Files Reviewed +- `configurations/route.ts` (GET/POST) +- `bkash/callback/route.ts` (GET) +- `sslcommerz/initiate/route.ts` (POST) +- `transactions/route.ts` (GET) + +### Findings + +| Check | configurations | bkash/callback | sslcommerz/initiate | transactions | +|-------|---------------|----------------|---------------------|-------------| +| Authentication | ✅ Manual | N/A (callback) | ✅ Manual | ✅ Manual | +| Store Isolation | ⚠️ Org-level only | ✅ Via paymentAttempt | ❌ **MISSING** | ✅ Via user stores | +| Input Validation | ⚠️ Partial | ✅ | ⚠️ Partial | ⚠️ No int bounds | +| CSRF | ❌ **MISSING** | N/A | ❌ **MISSING** | N/A (GET) | +| Rate Limiting | ❌ | ❌ | ❌ | ❌ | + +### Issues + +- **CRITICAL — `payments/configurations` POST has no permission check and no input validation on `config`.** Any authenticated user with an organization membership can update payment gateway credentials (API keys, secrets) for their organization. The `config` field is passed directly to the database without schema validation. An attacker who compromises any user account could: + - Replace bKash/SSLCommerz credentials to redirect payments. + - Enable payment gateways with malicious configurations. + - No CSRF protection means a cross-site attack could modify payment configs. +- **HIGH — `sslcommerz/initiate` does not verify store access.** The endpoint accepts `storeId` and `organizationId` in the request body without verifying the user has access to them. An authenticated user could initiate payments against any store. +- **MEDIUM — `payments/configurations` GET exposes organization structure.** Uses `membership.findFirst` with no role check. Any organization member (even with the lowest role) can read payment configuration metadata. +- **MEDIUM — `transactions` route computes stats by loading ALL payment attempts into memory.** For stores with high transaction volume, `prisma.paymentAttempt.findMany` with no limit will cause memory issues. +- **LOW — `bkash/callback` has good security.** Amount verification, currency verification, and idempotent updates are all present. The callback correctly resolves credentials by order's store scope. + +--- + +## 9. Webhooks Group (`/api/webhooks/`) + +### Files Reviewed +- `stripe/route.ts` (POST) +- `sslcommerz/ipn/route.ts` (POST) +- `pathao/route.ts` (POST) +- `[id]/route.ts` (GET/PATCH/DELETE) + +### Findings + +| Check | stripe | sslcommerz/ipn | pathao | [id] | +|-------|--------|----------------|--------|------| +| Signature Verification | ✅ Stripe signature | ✅ Hash + API validation | ✅ Token-based | N/A | +| Fail-Secure | ✅ | ✅ | ✅ | N/A | +| Amount Verification | ✅ (in service) | ✅ Tolerance check | N/A (shipping) | N/A | +| Idempotency | ⚠️ Uses `updateMany` | ✅ Status check | ❌ No dedup | N/A | +| Auth | ✅ `apiHandler` | N/A | N/A | ✅ `apiHandler` | + +### Issues + +- **MEDIUM — Stripe webhook `orderId` extraction is fragile.** The handler casts `result.data` as a Record and reads `orderId` from the event data. If the Stripe event metadata isn't populated correctly, `orderId` will be undefined, and the order update silently fails (the `if (orderId)` guard prevents errors but also silently drops events). +- **MEDIUM — Pathao webhook has no idempotency protection.** If Pathao retries the webhook, the order status will be re-applied. While this is generally safe for shipping status updates, the `adminNote` field gets appended each time, potentially growing unbounded. +- **LOW — `sslcommerz/ipn` correctly uses store-scoped credentials.** Good multi-tenant practice: it resolves SSLCommerz config from the transaction ID rather than using environment variables. +- **LOW — Pathao webhook returns order details in the response body.** Webhook responses should typically only acknowledge receipt. Returning order details (`id`, `orderNumber`, `status`) leaks internal data to the webhook caller. + +--- + +## 10. Cron Group (`/api/cron/`) + +### Files Reviewed +- `subscriptions/route.ts` (POST/GET) +- `cleanup/route.ts` (POST/GET) +- `release-reservations/route.ts` (GET/POST) + +### Findings + +| Check | subscriptions | cleanup | release-reservations | +|-------|--------------|---------|---------------------| +| Auth | ✅ Bearer token | ✅ Bearer token | ✅ Bearer token | +| Timing-Safe Compare | ⚠️ Custom impl | ✅ `crypto.timingSafeEqual` | ⚠️ Custom impl | +| Fail-Secure (no secret) | ✅ 503 | ✅ 503 | ✅ 503 | +| Error Handling | ✅ Per-job isolation | ✅ Per-job isolation | ✅ Try/catch | + +### Issues + +- **MEDIUM — Inconsistent timing-safe comparison implementations.** Three different implementations exist across the cron routes: + - `subscriptions` and `release-reservations` use a custom char-by-char XOR comparison that leaks string length (early return on length mismatch). + - `cleanup` correctly uses `crypto.createHash` + `timingSafeEqual` to avoid length leakage. + - All three should use the `cleanup` approach. +- **LOW — All cron routes alias `GET = POST`.** This is intentional for Vercel Cron compatibility. However, GET requests with side effects violate HTTP semantics and could be triggered by web crawlers or browser prefetching if the URLs are ever exposed. + +--- + +## 11. Stores Group (`/api/stores/[id]/`) + +### Files Reviewed +- `route.ts` (GET/PUT/PATCH/DELETE) +- `settings/route.ts` (GET/PATCH) +- `staff/route.ts` (GET/POST) +- `storefront/route.ts` (GET/PATCH/PUT) + +### Findings + +| Check | stores/[id] | settings | staff | storefront | +|-------|-------------|----------|-------|------------| +| Authentication | ✅ `apiHandler` | ✅ `apiHandler` | ✅ `apiHandler` + session | ✅ Manual | +| Store Access | ✅ `requireStoreAccessCheck` | ❌ **MISSING** | ✅ Custom check | ✅ Custom check | +| Permission | ✅ Per-method | ✅ `stores:read/update` | ✅ `staff:read/create` | ✅ Custom | +| Input Validation | ✅ Zod | ✅ Zod | ✅ Zod | ✅ Zod | +| CSRF | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ✅ Via `apiHandler` | ❌ **MISSING** | + +### Issues + +- **HIGH — `stores/[id]/settings` does not verify store access.** The GET and PATCH handlers validate the `storeId` from the URL param with Zod but never call `requireStoreAccessCheck` or `verifyStoreAccess`. Any user with `stores:read` or `stores:update` permission can read/modify settings for any store. The route returns mock data currently, but this access control gap will become a real vulnerability when connected to a database. +- **HIGH — `stores/[id]/storefront` bypasses `apiHandler` for all methods.** The GET, PATCH, and PUT handlers are raw function exports. No CSRF protection on PATCH/PUT. The route correctly implements its own permission check, but misses the middleware's content-type, body-size, and error handling protections. +- **LOW — `staff` route has good access control.** Both GET and POST verify store access with a custom `checkStoreAccess` function that checks ownership, staff membership, and org membership. + +--- + +## Cross-Cutting Issues + +### 1. Inconsistent Middleware Adoption (Severity: HIGH) + +**Routes using `apiHandler`:** products/, products/[id], products/import, customers/, customers/export, checkout/*, orders/[id]/status, orders/[id]/cancel, orders/[id]/refund, stores/[id], stores/[id]/settings, webhooks/[id], subscriptions/subscribe + +**Routes bypassing `apiHandler`:** orders/ (GET/POST), orders/[id] (GET/PATCH/DELETE), admin/subscriptions, products/bulk, products/export, customers/bulk, subscriptions/cancel, subscriptions/upgrade, subscriptions/downgrade, payments/configurations, payments/sslcommerz/initiate, payments/transactions, stores/[id]/storefront + +**Impact:** Routes that bypass `apiHandler` miss: +- CSRF protection for state-changing requests +- `Content-Type: application/json` enforcement +- Request body size limits (1MB max) +- Centralized error handling with log scrubbing in production + +### 2. Missing Rate Limiting (Severity: HIGH) + +Only 2 out of 50+ routes apply rate limiting: +- `auth/signup` — `authRateLimit` (10/min) +- `admin/users` — `searchRateLimit` (30/min) + +The following sensitive endpoints have **no rate limiting**: +- All subscription management (upgrade, downgrade, cancel) +- All payment initiation endpoints +- Order creation +- Bulk operations (products/bulk, customers/bulk) +- Admin subscription management + +### 3. Excessive Console Logging (Severity: MEDIUM) + +Multiple routes contain `console.log` statements that output sensitive information: +- `orders/route.ts` — 14 console statements including payment gateway URLs, session keys, and full order data +- `orders/[id]/route.ts` — logs session user IDs, full request bodies, and store access decisions +- `products/[id]/route.ts` — logs storeId, variant counts +- `payments/bkash/callback/route.ts` — logs payment execution results +- `subscriptions/upgrade/route.ts` — logs healing operations + +These should use a structured logger (like the existing `apiLogger`) with environment-aware log levels. + +### 4. Response Format Inconsistency (Severity: LOW) + +The codebase uses three different response patterns: +1. **`createSuccessResponse`/`createErrorResponse`** — from `api-middleware.ts` (used by ~60% of routes) +2. **`successResponse`/`errorResponse`** — from `api-response.ts` (used by bulk routes) +3. **Raw `NextResponse.json`** — used by manually authored routes + +This makes it harder for frontend code to have a unified response parser. + +### 5. `products/import` Content-Type Conflict (Severity: HIGH — Functional Bug) + +The `products/import` route uses `apiHandler({ permission: 'products:create' })`, which triggers the `withApiMiddleware` function. That middleware enforces `Content-Type: application/json` for POST requests (line 463 of `api-middleware.ts`). However, the import route reads `request.formData()`, which requires `multipart/form-data`. This means the middleware will reject every import request with a 415 error before the handler runs. The import endpoint is likely non-functional. + +--- + +## Recommendations (Priority Order) + +### P0 — Critical / Immediate + +1. **Fix `payments/configurations` POST** — Add Zod validation on the `config` field, require an admin-level permission (e.g., `payments:configure`), and add store-level isolation. +2. **Fix `products/import` Content-Type conflict** — Either add `skipCsrf: true` to the `apiHandler` options and handle Content-Type validation manually, or extract the import handler outside `apiHandler` while preserving auth and permission checks. + +### P1 — High / This Sprint + +3. **Migrate all raw routes to `apiHandler`** — Focus on `orders/route.ts`, `admin/subscriptions`, `subscriptions/cancel|upgrade|downgrade`, `products/bulk`, `customers/bulk`, `payments/sslcommerz/initiate`, and `stores/[id]/storefront`. +4. **Add store access checks to** `customers/` POST, `customers/export`, and `stores/[id]/settings`. +5. **Add rate limiting to financial endpoints** — at minimum: subscription upgrade, payment initiation, order creation, and bulk operations. + +### P2 — Medium / Next Sprint + +6. **Standardize timing-safe comparison** — Extract the `cleanup` cron's `constantTimeCompare` (SHA-256 digest + `timingSafeEqual`) into a shared utility and use it in all cron routes. +7. **Add rate limiting to `verify-email`** — even though the 256-bit token is practically unguessable. +8. **Audit and reduce `console.log` usage** — Replace with `apiLogger` calls gated behind environment checks. +9. **Fix the unauthenticated order lookup** — the `storeId || ''` fallback in `orders/[id]` GET could return orders from the wrong store. + +### P3 — Low / Backlog + +10. **Standardize response format** — deprecate `api-response.ts` helpers in favor of `api-middleware.ts` `createSuccessResponse`/`createErrorResponse`. +11. **Review checkout authentication model** — decide if checkout routes should be public (for guest checkout) or authenticated, and adjust permissions accordingly. +12. **Add `Idempotency-Key` support** to all financial POST endpoints (subscription upgrade, payment initiation) to prevent double-charging. diff --git a/docs/cursor/review/00-session-progress.md b/docs/cursor/review/00-session-progress.md new file mode 100644 index 00000000..a1e5d071 --- /dev/null +++ b/docs/cursor/review/00-session-progress.md @@ -0,0 +1,122 @@ +# Review Session Progress & Status + +**Session Date:** April 1, 2026 +**Branch:** `cursor/comprehensive-repository-project-review-24a0` + +--- + +## Completed Tasks + +### 1.

Multi-tenant isolation depends entirely on application code. +2. **JSON string fields**: Several fields store JSON as `String` instead of `Json` type (`permissions`, `options`, `images`, `shippingAddress`). This prevents database-level JSON querying and validation. +3. **Monetary values as `Int`**: Amounts stored as integers (presumably paisa/cents) - good practice but needs documentation. +4. **Missing `deletedAt` on some models**: `StoreStaff`, `PaymentAttempt`, `Fulfillment` lack soft delete capability. +5. **Duplicate `DiscountType`**: `FIXED_AMOUNT` and `FIXED` appear to be the same concept in the enum. + +--- + +## 4.

Security Assessment + +### Critical Vulnerabilities + +#### SEC-001: Payment Configuration API Missing Authorization (CRITICAL) +- **Location**: `src/app/api/payments/configurations/route.ts` +- **Issue**: POST handler allows any authenticated user with org membership to update payment gateway credentials without permission checks +- **Impact**: An attacker could redirect payment flows by changing Stripe/SSLCommerz credentials +- **Fix**: Add `payments:manage` permission check + +#### SEC-002: bKash/Nagad Payment Services Completely Stubbed (CRITICAL) +- **Location**: `src/lib/payments/providers/bkash.service.ts`, `nagad.service.ts` +- **Issue**: Both services return mock/empty responses for all operations. No actual API integration exists. +- **Impact**: Payment attempts via bKash/Nagad silently fail without recording transactions +- **Fix**: Implement full API integration or remove from payment options + +#### SEC-003: AES-256-CBC Without Authentication (HIGH) +- **Location**: `src/lib/encryption.ts` +- **Issue**: Uses AES-256-CBC for encrypting payment credentials. CBC mode without HMAC authentication is vulnerable to padding oracle attacks. +- **Fix**: Switch to AES-256-GCM (authenticated encryption) + +#### SEC-004: CSRF Origin Check Trusts Spoofable Headers (HIGH) +- **Location**: `src/lib/csrf.ts` +- **Issue**: CSRF validation reads `x-forwarded-host` header which is user-controllable without trusted proxy +- **Fix**: Validate `Origin` header directly or use `host` header with known-good list + +#### SEC-005: ~40% of API Routes Bypass Centralized Middleware (HIGH) +- **Location**: Various route files across `src/app/api/` +- **Issue**: Routes like `orders/`, `admin/subscriptions`, `subscriptions/*`, `products/bulk`, `customers/bulk`, `stores/[id]/storefront` use raw handlers instead of `apiHandler` +- **Impact**: These routes miss CSRF protection, content-type validation, body-size limits +- **Fix**: Wrap all mutation routes in `apiHandler` + +#### SEC-006: Minimal Rate Limiting Coverage (HIGH) +- **Issue**: Only ~2 of 291 routes apply rate limiting +- **Impact**: Financial operations (subscription upgrades, payment initiation, order creation) and bulk operations vulnerable to abuse +- **Fix**: Apply rate limiting to all mutation endpoints, especially financial ones + +#### SEC-007: Missing Multi-Tenant Isolation on Several Routes (HIGH) +- **Location**: `customers/` POST, `customers/export`, `stores/[id]/settings`, `sslcommerz/initiate` +- **Issue**: These routes accept a `storeId` from the request body without verifying the user belongs to that store +- **Fix**: Always derive storeId from session/membership, never from request body + +#### SEC-008: Nagad Service Hardcodes Sandbox Mode (MEDIUM) +- **Location**: `src/lib/payments/providers/nagad.service.ts` +- **Issue**: `mode: 'sandbox'` is hardcoded, so production payments would always use sandbox endpoints +- **Fix**: Read mode from environment variable + +### Security Strengths +- HSTS, X-Content-Type-Options, X-Frame-Options, CSP headers configured in `next.config.ts` +- X-Powered-By header removed +- Input sanitization via DOMPurify in `src/lib/security/xss-protection.ts` +- Audit logging infrastructure in place +- Password hashing with bcryptjs +- API token system with scoped permissions + +--- + +## 8.

Every import request gets rejected with 415. +- **Fix**: Use raw handler for file upload routes or modify middleware to support multipart + +#### ARCH-004: Inconsistent API Response Patterns +- **Issue**: Some routes use `apiResponse()` helper, others use raw `NextResponse.json()`. Error formats vary. +- **Fix**: Standardize all routes through `apiHandler` wrapper + +#### ARCH-005: TypeScript Build Errors Ignored +- **Configuration**: `typescript.ignoreBuildErrors: true` in `next.config.ts` +- **Issue**: Type errors are silently ignored during build, potentially masking runtime bugs +- **Recommendation**: Fix type errors and enable strict checking + +--- + +## 9.

Security Vulnerabilities + +### SEC-001: Payment Configuration Missing Authorization (CRITICAL) + +- **File:** `src/app/api/payments/configurations/route.ts` +- **Issue:** POST handler allows any authenticated user with organization membership to create/update payment gateway credentials. No permission check (e.g., `payments:manage`) is enforced. +- **Impact:** Malicious authenticated user could modify Stripe secret keys, SSLCommerz credentials, or other payment gateway configurations to redirect payments. +- **Fix:** + ```typescript + // Add permission check + const hasPermission = await checkPermission(session, 'payments:manage'); + if (!hasPermission) return apiResponse.forbidden(); + ``` + +### SEC-002: bKash Payment Service Returns Mock Data (CRITICAL) + +- **File:** `src/lib/payments/providers/bkash.service.ts` +- **Issue:** All methods (`initiate`, `verify`, `refund`) return hardcoded mock/empty responses. No actual bKash API integration exists. +- **Impact:** If a store enables bKash payments, customer payments silently fail with no database records, causing potential revenue loss. +- **Fix:** Either fully implement the bKash API integration or remove bKash from available payment options in the UI. + +### SEC-003: Nagad Payment Service Returns Mock Data (CRITICAL) + +- **File:** `src/lib/payments/providers/nagad.service.ts` +- **Issue:** Same as SEC-002 but for Nagad. Additionally, `mode: 'sandbox'` is hardcoded regardless of environment. +- **Impact:** Production payments via Nagad would be sent in sandbox mode. +- **Fix:** Same as SEC-002 - implement or remove. + +### SEC-004: AES-256-CBC Without Authentication (HIGH) + +- **File:** `src/lib/encryption.ts` +- **Issue:** Uses AES-256-CBC for encrypting payment gateway credentials stored in the database. CBC mode without HMAC authentication is vulnerable to padding oracle attacks. +- **Impact:** An attacker with database write access could modify ciphertext to alter decrypted credentials without detection. +- **Fix:** + ```typescript + // Switch to AES-256-GCM (authenticated encryption) + const cipher = crypto.createCipheriv('aes-256-gcm', key, iv); + // Store auth tag alongside ciphertext + ``` + +### SEC-005: CSRF Validation Trusts x-forwarded-host Header (HIGH) + +- **File:** `src/lib/csrf.ts` +- **Issue:** CSRF origin validation reads `x-forwarded-host` header, which is user-controllable in environments without a trusted reverse proxy stripping it. +- **Impact:** Attacker could bypass CSRF protection by setting `x-forwarded-host` to match the application's expected origin. +- **Fix:** Validate `Origin` header directly. On Vercel, `x-forwarded-host` is trustworthy, but add explicit proxy trust configuration. + +### SEC-006: ~40% of Mutation Routes Bypass apiHandler Middleware (HIGH) + +- **Files:** Multiple route files across `src/app/api/` +- **Affected Routes Include:** + - `orders/route.ts` + - `admin/subscriptions/route.ts` + - `subscriptions/cancel/route.ts`, `upgrade/route.ts`, `downgrade/route.ts` + - `products/bulk/route.ts` + - `customers/bulk/route.ts` + - `stores/[id]/storefront/route.ts` +- **Issue:** These routes use raw `NextResponse.json()` handlers instead of the `apiHandler` wrapper, bypassing CSRF protection, content-type validation, body-size limits, and centralized error handling. +- **Impact:** Inconsistent security enforcement across the API surface. +- **Fix:** Wrap all mutation endpoints in `apiHandler`. + +### SEC-007: Only ~2 of 291 Routes Apply Rate Limiting (HIGH) + +- **Issue:** Vast majority of API routes have no rate limiting. +- **Critical Unprotected Routes:** + - `POST /api/subscriptions/subscribe` (financial) + - `POST /api/subscriptions/upgrade` (financial) + - `POST /api/payments/sslcommerz/initiate` (financial) + - `POST /api/orders` (order creation) + - `POST /api/products/bulk` (bulk operations) + - `POST /api/customers/bulk` (bulk operations) + - `POST /api/auth/signup` (account creation) +- **Fix:** Apply tiered rate limiting: stricter for financial/auth endpoints, moderate for mutations, lighter for reads. + +### SEC-008: Missing Multi-Tenant Isolation on Specific Routes (HIGH) + +- **Files:** + - `src/app/api/customers/route.ts` (POST) + - `src/app/api/customers/export/route.ts` + - `src/app/api/stores/[id]/settings/route.ts` + - `src/app/api/payments/sslcommerz/initiate/route.ts` +- **Issue:** These routes accept `storeId` from the request body without verifying the authenticated user has access to that store. +- **Impact:** IDOR vulnerability - user could access/modify data belonging to another store. +- **Fix:** Always derive `storeId` from the authenticated session's membership, never from the request body. + +### SEC-009: TypeScript Build Errors Silently Ignored (MEDIUM) + +- **File:** `next.config.ts` line 13 +- **Issue:** `typescript.ignoreBuildErrors: true` suppresses all type errors during build. +- **Impact:** Type errors that could indicate security bugs (incorrect type casts, missing null checks) go undetected. +- **Fix:** Enable strict type checking and resolve existing errors. + +### SEC-010: Webhook Secret Not Validated Consistently (MEDIUM) + +- **Files:** Various webhook route handlers +- **Issue:** Some webhook handlers verify signatures, others accept payloads without validation. +- **Impact:** Spoofed webhook events could trigger unauthorized actions. +- **Fix:** Ensure all webhook handlers validate signatures before processing. + +### SEC-011: No Content-Security-Policy Nonce for Inline Scripts (MEDIUM) + +- **File:** `next.config.ts` +- **Issue:** CSP includes `'unsafe-inline'` and `'unsafe-eval'` for scripts, weakening XSS protection. +- **Impact:** Inline script injection could bypass CSP. +- **Fix:** Use nonce-based CSP with Next.js Script component. + +--- + +## 2. Architectural Issues + +### ARCH-001: Triple-Redundant Redis Implementation + +- **Files:** + - `src/lib/redis.ts` - ioredis client + - `src/lib/redis-upstash.ts` - @upstash/redis client + - `src/lib/cache/cache-service.ts` - Another ioredis client +- **Issue:** Three separate Redis client initializations with different connection handling. +- **Impact:** Wasted connections, inconsistent behavior, maintenance burden. +- **Recommendation:** Consolidate to a single Redis client factory. + +### ARCH-002: Triple-Redundant Rate Limiting + +- **Files:** + - `src/lib/rate-limit.ts` - Redis-based rate limiter + - `src/lib/rate-limiter.ts` - Different API for rate limiting + - `src/middleware/rate-limit.ts` - Middleware-level rate limiting + - `src/lib/security/rate-limit.ts` - Yet another implementation +- **Issue:** Four different rate limiting implementations with incompatible APIs. +- **Recommendation:** Choose one implementation and apply consistently. + +### ARCH-003: NextAuth v4 Instead of Auth.js v5 + +- **File:** `src/lib/auth.ts` +- **Issue:** NextAuth v4 is used while Auth.js v5 is the recommended version for Next.js 15+/16+. +- **Impact:** Missing built-in server component integration, middleware-based auth, newer security patterns. +- **Recommendation:** Plan phased migration to Auth.js v5. + +### ARCH-004: No PostgreSQL Row Level Security + +- **File:** `prisma/schema.prisma` +- **Issue:** Multi-tenant data isolation relies entirely on application code filtering by `storeId`. +- **Impact:** Any application bug that omits the `storeId` filter could leak data across tenants. +- **Recommendation:** Implement PostgreSQL RLS policies as defense-in-depth. + +### ARCH-005: Product Import Content-Type Conflict + +- **File:** `src/app/api/products/import/route.ts` +- **Issue:** The `apiHandler` middleware enforces `Content-Type: application/json`, but this route expects `multipart/form-data` for CSV upload. +- **Impact:** All product import attempts fail with 415 Unsupported Media Type. +- **Fix:** Use raw handler for file upload endpoints. + +### ARCH-006: Subscription Route Duplication + +- **Files:** + - `src/app/api/subscription/` (4 endpoints) + - `src/app/api/subscriptions/` (18 endpoints) +- **Issue:** Two separate route groups for subscription management with overlapping functionality (e.g., both have `plans` endpoints). +- **Recommendation:** Merge into single `subscriptions/` group. + +### ARCH-007: WebSocket Server Not Integrated + +- **File:** `src/lib/websocket/server.ts` +- **Issue:** Socket.io server is initialized but not integrated into the Next.js server lifecycle. Vercel serverless functions don't support persistent WebSocket connections. +- **Impact:** WebSocket functionality is non-functional on Vercel deployment. +- **Recommendation:** Use SSE (already partially implemented) or Vercel's Realtime API for real-time features. + +--- + +## 3. Code Quality Issues + +### CQ-001: JSON Stored as String in Multiple Models + +- **Models Affected:** `CustomRole.permissions`, `CustomRoleRequest.permissions`, `ProductVariant.options`, `Product.images`, `Order.shippingAddress`, `Store.storefrontConfig*` +- **Issue:** JSON data stored as `String` type instead of Prisma's `Json` type. +- **Impact:** No database-level JSON validation, requires manual `JSON.parse()` everywhere, prevents JSON path queries. +- **Fix:** Migrate to `Json` type with proper migration. + +### CQ-002: Inconsistent Hook Naming + +- **Files:** + - `src/hooks/use-mobile.ts` (kebab-case) + - `src/hooks/useApiQuery.ts` (camelCase) + - `src/hooks/useOrderStream.ts` (camelCase, but file says `use-order-stream.ts` in some contexts) +- **Recommendation:** Standardize to kebab-case filenames (`use-xxx.ts`). + +### CQ-003: Backup File in Source + +- **File:** `src/components/landing-pages/landing-page-editor-client.tsx.bak` +- **Issue:** Backup file committed to repository. +- **Fix:** Delete the `.bak` file. + +### CQ-004: Inconsistent Error Response Formats + +- **Issue:** Some routes return `{ error: "message" }`, others return `{ success: false, error: "message" }`, and some use `apiResponse` helpers. +- **Impact:** Client-side error handling must account for multiple formats. +- **Fix:** Standardize all API responses through `apiResponse` helper. + +### CQ-005: Magic Numbers in Subscription Logic + +- **Files:** Various files in `src/lib/subscription/` +- **Issue:** Grace period days (3), trial days (7), max retries (3) are scattered as magic numbers. +- **Fix:** Move to constants or read from `SubscriptionPlanModel` configuration. + +### CQ-006: Missing Error Boundaries + +- **Files:** `src/app/dashboard/` pages +- **Issue:** Only a few dashboard pages have `error.tsx` boundary files (categories, customers, inventory, orders, products). Most dashboard routes lack error boundaries. +- **Fix:** Add error boundaries to all major route groups. + +--- + +## 4.
