[Remediation Priority Matrix](#remediation-priority-matrix) + +--- + +## Critical Security Vulnerabilities + +### VULN-001: AES-256-CBC Without Authentication Tag +- **File:** `src/lib/encryption.ts` +- **Severity:** Critical +- **Description:** The credential encryption uses AES-256-CBC mode without an authentication tag (MAC/HMAC). This makes encrypted data vulnerable to **padding oracle attacks**, allowing an attacker to decrypt ciphertext by observing error responses during decryption attempts. +- **Impact:** Third-party credentials (Facebook tokens, Pathao keys, payment gateway secrets) stored at rest could be decrypted by an attacker with database read access. +- **Recommendation:** Migrate to AES-256-GCM which provides authenticated encryption. Add a version byte prefix to ciphertext to support backward-compatible migration: + ```typescript + // Use AES-256-GCM instead of CBC + const cipher = crypto.createCipheriv('aes-256-gcm', key, iv); + // Store: version(1) + iv(12) + ciphertext + authTag(16) + ``` +- **Priority:** Immediate + +### VULN-002: Missing CSRF Protection on Order Routes +- **File:** `src/app/api/orders/route.ts`, `src/app/api/orders/[id]/route.ts` +- **Severity:** Critical +- **Description:** These route files use raw `export async function POST/PATCH/DELETE` instead of the `apiHandler` wrapper. This completely bypasses the CSRF protection middleware. An attacker could craft a malicious website that submits order creation/modification requests on behalf of authenticated users. +- **Impact:** Unauthorized order creation, status changes, and cancellations. +- **Recommendation:** Refactor to use `apiHandler` or manually call `validateCsrfTokenFromRequest()` in each handler. +- **Priority:** Immediate + +### VULN-003: No Authorization on Payment Configuration +- **File:** `src/app/api/payments/configurations/route.ts` +- **Severity:** Critical +- **Description:** The payment configuration endpoint has no permission check. Any authenticated user (including CUSTOMER role) can read and modify payment gateway configurations including API keys and secrets. +- **Impact:** Attacker could redirect payment flows, steal gateway credentials, or disable payment processing for stores. +- **Recommendation:** Add `permission: 'payments:admin'` check and require OWNER/ADMIN role. Use `apiHandler` wrapper. +- **Priority:** Immediate + +### VULN-004: Cross-Tenant Order Updates in Stripe Webhook +- **File:** `src/app/api/webhooks/stripe/route.ts` +- **Severity:** Critical +- **Description:** Order status updates use `prisma.order.update({ where: { id: orderId } })` without a `storeId` filter. If an attacker can inject a valid `orderId` into Stripe metadata (e.g., via a compromised store), they could trigger status changes on orders belonging to other stores. +- **Impact:** Cross-tenant data manipulation, payment status fraud. +- **Recommendation:** Always include `storeId` in the `where` clause: `{ where: { id: orderId, storeId: expectedStoreId } }`. +- **Priority:** Immediate + +--- + +## High Severity Issues + +### VULN-005: CSP Allows `'unsafe-eval'` in Production +- **File:** `src/lib/security.ts` (line ~28), `next.config.ts` (CSP header) +- **Severity:** High +- **Description:** The Content Security Policy includes `'unsafe-eval'` in the `script-src` directive. This allows JavaScript `eval()`, `Function()`, and similar constructs, significantly weakening XSS protections. +- **Impact:** If any XSS vector exists, the attacker can execute arbitrary JavaScript including `eval()`. +- **Recommendation:** Remove `'unsafe-eval'` from production CSP. Use nonce-based CSP for inline scripts. Add `'strict-dynamic'` where appropriate. + +### VULN-006: Duplicate CSRF Implementations +- **Files:** `src/lib/csrf.ts` (HMAC-signed stateless), `src/lib/security/csrf.ts` (cookie-based) +- **Severity:** High +- **Description:** Two entirely different CSRF protection systems exist. `api-middleware.ts` uses the HMAC-signed version, but the cookie-based version is also exported and could be used inconsistently. +- **Impact:** Confusion about which CSRF implementation to use. One may be weaker than the other. +- **Recommendation:** Consolidate to a single CSRF implementation. Remove the unused one. Document the canonical approach. + +### VULN-007: Four Duplicate Rate Limiting Implementations +- **Files:** + - `src/lib/rate-limit.ts` (Upstash Redis, fixed window) + - `src/lib/rate-limiter.ts` (Prisma database) + - `src/lib/security/rate-limit.ts` (Redis + memory fallback, sliding window) + - `src/middleware/rate-limit.ts` (middleware helper) +- **Severity:** High +- **Description:** Four separate rate-limiting implementations with different algorithms and backing stores. Most API routes have no rate limiting at all because there's no clear canonical choice. +- **Impact:** Inconsistent protection. Developers skip rate limiting due to confusion. +- **Recommendation:** Choose one implementation (recommend `security/rate-limit.ts` with sliding window + Redis). Deprecate and remove others. Apply to all API routes via `apiHandler`. + +### VULN-008: Guest Order Lookup Without Rate Limiting +- **File:** `src/app/api/orders/[id]/route.ts` +- **Severity:** High +- **Description:** The guest order lookup path (unauthenticated) allows querying orders by ID + email/phone without any rate limiting. An attacker can enumerate order IDs and guess associated email addresses. +- **Impact:** Order information disclosure, customer data leakage. +- **Recommendation:** Apply aggressive rate limiting (5 requests/minute per IP) to the guest lookup path. + +### VULN-009: Timing-Unsafe String Comparison +- **File:** `src/lib/security.ts` (line ~141) +- **Severity:** High +- **Description:** `constantTimeCompare` returns `false` immediately when string lengths differ, leaking length information through response timing. +- **Impact:** Attacker can determine the correct length of tokens/secrets. +- **Recommendation:** Pad both strings to the same length before comparison, or use Node's `crypto.timingSafeEqual` directly. + +### VULN-010: No Brute-Force Protection on Login +- **File:** `src/app/api/auth/[...nextauth]/route.ts` +- **Severity:** High +- **Description:** The NextAuth credentials callback has no rate limiting. An attacker can attempt unlimited password guesses. +- **Impact:** Account takeover via credential stuffing or brute-force attacks. +- **Recommendation:** Add rate limiting to the NextAuth handler or implement account lockout after N failed attempts. + +--- + +## Medium Severity Issues + +### VULN-011: Unfiltered Error Details in API Responses +- **File:** `src/lib/api-response.ts` +- **Description:** The `errorResponse` function passes an `unknown` `details` parameter directly to the JSON response. Callers may inadvertently pass stack traces, internal file paths, or database error messages. +- **Recommendation:** Whitelist allowed detail fields. Strip stack traces in production. + +### VULN-012: CSRF Same-Origin Bypass +- **File:** `src/lib/csrf.ts` (line ~219) +- **Description:** `isSameOriginRequest` trusts the `x-forwarded-host` header. If a reverse proxy doesn't sanitize this header, an attacker can set it to match the origin and bypass CSRF protection. +- **Recommendation:** Only trust `x-forwarded-host` from known trusted proxies. Validate against a whitelist. + +### VULN-013: Weak Input Sanitization +- **File:** `src/lib/security.ts` (line ~51) +- **Description:** `sanitizeString` only removes `<>` characters, which is trivially bypassable (e.g., `javascript:` URLs, event handler attributes). This function provides a false sense of security. +- **Recommendation:** Use DOMPurify (already available via `isomorphic-dompurify`) for all HTML sanitization. Deprecate `sanitizeString`. + +### VULN-014: Stateful Regex Race Condition +- **File:** `src/lib/security.ts` (line ~233) +- **Description:** `hasSqlInjectionPattern` uses regex with the `g` flag, which maintains state across calls via `lastIndex`. Calling the function multiple times on the same regex produces alternating true/false results. +- **Recommendation:** Remove the `g` flag from the regex or create a new RegExp instance per call. + +### VULN-015: Rate Limiting Fails Open +- **Files:** `src/lib/rate-limit.ts`, `src/lib/security/rate-limit.ts` +- **Description:** When Redis is unavailable, all rate limiting is silently disabled. An attacker could DoS the Redis instance to bypass rate limits. +- **Recommendation:** Implement in-memory fallback rate limiting (already partially done in `security/rate-limit.ts`). Log warnings in production. + +### VULN-016: No PostgreSQL Row-Level Security +- **File:** `prisma/schema.prisma` +- **Description:** Multi-tenancy relies entirely on application-level `storeId` filtering. A single missed filter in any query could expose cross-tenant data. +- **Recommendation:** Implement PostgreSQL RLS policies as defense-in-depth. Set `app.current_store_id` in each connection's session context. + +### VULN-017: Missing Store Access Verification on Checkout +- **File:** `src/app/api/checkout/complete/route.ts` +- **Description:** The `apiHandler` is not configured with `requireStore: true`, so store access is not verified at the middleware level. +- **Recommendation:** Add `requireStore: true` to the `apiHandler` configuration. + +### VULN-018: Incomplete Environment Variable Validation +- **File:** `src/lib/env.ts` +- **Description:** The env validation schema doesn't include security-critical variables like `CSRF_SECRET`, `CREDENTIALS_ENCRYPTION_KEY`, `UPSTASH_REDIS_REST_URL`. +- **Recommendation:** Add all security-critical env vars to the validation schema with appropriate constraints. + +### VULN-019: Memory Store Unbounded Growth +- **File:** `src/lib/security/rate-limit.ts` +- **Description:** The in-memory rate limit fallback store (`InMemoryRateLimitStore`) has no size limit. An attacker rotating IPs could exhaust server memory. +- **Recommendation:** Add a maximum entry count (e.g., 100K) with LRU eviction. + +--- + +## Low Severity Issues + +### VULN-020: Permission Names in Error Messages +- **File:** `src/lib/api-middleware.ts` (line ~332) +- **Description:** Error message reveals internal permission identifiers: "Access denied. You do not have permission: {permission}". +- **Recommendation:** Return generic "Access denied" without specifying the required permission. + +### VULN-021: Modulo Bias in Token Generation +- **File:** `src/lib/security.ts` (line ~162) +- **Description:** `generateSecureToken` uses `randomValues[i] % chars.length` with 62 characters. Since 256 % 62 !== 0, some characters are more probable. +- **Recommendation:** Use rejection sampling or `crypto.randomUUID()` based approaches. + +### VULN-022: Verbose Production Logging +- **Files:** `src/app/api/products/[id]/route.ts`, `src/app/api/orders/route.ts`, `src/app/api/orders/[id]/route.ts` +- **Description:** `console.log` statements expose user IDs, store IDs, monetary amounts, and customer emails in production logs. +- **Recommendation:** Replace with structured logging at appropriate levels. Redact sensitive fields. + +### VULN-023: `__Host-` Cookie Prefix Without HTTPS in Dev +- **File:** `src/lib/security/csrf.ts` +- **Description:** The `__Host-csrf-token` cookie name requires the `Secure` attribute, but dev mode sets `secure: false`. Browsers reject `__Host-` cookies without `Secure`. +- **Recommendation:** Use a different cookie name in development or always set `secure: true` with local HTTPS. + +--- + +## Architectural Misimplementations + +### ARCH-001: Missing Next.js Edge Middleware +- **Description:** There is no `middleware.ts` at the project root. This means there's no route-level authentication guard, no redirect for unauthenticated users to login, and no tenant context resolution at the edge. +- **Impact:** Authentication checks happen in each API route handler individually, leading to inconsistency. +- **Recommendation:** Add `middleware.ts` at project root with auth redirects and tenant resolution. + +### ARCH-002: Dual Session Caching Layers +- **Files:** `src/lib/get-session.ts`, `src/lib/cached-session.ts` +- **Description:** Two separate modules provide session caching with `React.cache()`. Different parts of the codebase use different modules. +- **Impact:** Inconsistent session handling, potential double-fetching. +- **Recommendation:** Consolidate into one module. + +### ARCH-003: Dual Store Access Verification +- **Files:** `src/lib/get-current-user.ts`, `src/lib/security/tenant-resolver.ts` +- **Description:** Two separate implementations for verifying store access authorization. +- **Impact:** Different behavior for the same check. +- **Recommendation:** Consolidate into `tenant-resolver.ts`. + +### ARCH-004: Service Layer Transaction Safety +- **File:** `src/lib/services/order-processing.service.ts` +- **Description:** `InventoryService.deductStockForOrder` runs its own `$transaction` inside the outer checkout transaction. Nested transactions in Prisma use savepoints, but this pattern is fragile. +- **Impact:** Inventory deduction could succeed while order creation fails, or vice versa. +- **Recommendation:** Accept a `tx: Prisma.TransactionClient` parameter and use the outer transaction. + +### ARCH-005: Inconsistent Route Handler Patterns +- **Description:** Some routes use `apiHandler` (secure), some use raw exports (insecure), some use a mix. +- **Impact:** Security properties vary by route without clear indication. +- **Recommendation:** Mandate `apiHandler` for all routes. Lint rule to detect raw exports. + +### ARCH-006: Store Model Bloat +- **File:** `prisma/schema.prisma` (Store model) +- **Description:** The Store model has 10+ Pathao-specific fields directly on it. This violates single responsibility and makes the model unwieldy. +- **Recommendation:** Extract to a `PathaoConfig` model with a one-to-one relation to Store. + +--- + +## Incomplete/Irrelevant/Duplicate Code + +### CODE-001: bKash and Nagad Payment Providers (Stubs) +- **Files:** `src/lib/payments/providers/bkash.service.ts`, `src/lib/payments/providers/nagad.service.ts` +- **Description:** These payment providers have stub implementations that don't persist payment state to the database. +- **Impact:** Payments through these gateways would be lost if the process restarts between creation and callback. +- **Status:** Incomplete + +### CODE-002: Backup File Committed +- **File:** `src/components/landing-pages/landing-page-editor-client.tsx.bak` +- **Description:** A `.bak` backup file has been committed to the repository. +- **Recommendation:** Delete and add `*.bak` to `.gitignore`. + +### CODE-003: Redundant `radix-ui` Unified Package +- **File:** `package.json` +- **Description:** Both the unified `radix-ui` package and 24 individual `@radix-ui/*` packages are installed. The unified package is not imported anywhere. +- **Recommendation:** Remove `radix-ui` from dependencies. + +### CODE-004: Dual Icon Libraries +- **File:** `package.json` +- **Description:** Both `lucide-react` and `@tabler/icons-react` are used across different components. +- **Recommendation:** Standardize on one icon library. + +### CODE-005: Deprecated `requireAuth` Function +- **File:** `src/lib/multi-tenancy.ts` +- **Description:** Marked as `@deprecated` but still exported and potentially used. +- **Recommendation:** Remove and update callers. + +### CODE-006: DiscountType Enum Ambiguity +- **File:** `prisma/schema.prisma` +- **Description:** `DiscountType` has both `FIXED_AMOUNT` and `FIXED` values. These appear to mean the same thing. +- **Recommendation:** Consolidate to one value and migrate existing data. + +### CODE-007: JSON Data Stored as String +- **File:** `prisma/schema.prisma` +- **Description:** Several JSON fields are stored as `String` instead of `Json` type: `storefrontConfig`, `permissions` (CustomRole), `orderData` (FacebookOrder), etc. +- **Impact:** Cannot use JSON query operators, no schema validation at database level. +- **Recommendation:** Migrate to `Json` type with proper migration. + +### CODE-008: Multiple `hasPermission` Implementations +- **Files:** `permissions.ts`, `get-session.ts`, `api-middleware.ts` +- **Description:** Three different implementations with varying wildcard support levels. +- **Recommendation:** Use single canonical implementation from `permissions.ts`. + +--- + +## Error Handling Issues + +### ERR-001: Generic Error Messages Expose Internal Details +- **Files:** Various API routes +- **Description:** Some catch blocks return `Error.message` directly to clients, which may contain database error details, file paths, or stack traces. +- **Recommendation:** Return generic error messages. Log details server-side only. + +### ERR-002: Missing Error Boundaries in Key Pages +- **Description:** Dashboard pages like `/dashboard/products`, `/dashboard/orders` have `error.tsx` boundaries, but many pages (settings, integrations, subscriptions) do not. +- **Recommendation:** Add `error.tsx` to all route segments. + +### ERR-003: Unhandled Promise Rejections in Webhook Handlers +- **Description:** Webhook handlers fire-and-forget some operations (e.g., webhook delivery notifications) without awaiting. Unhandled rejections may crash the serverless function. +- **Recommendation:** Always `await` or use `.catch()` on all promises within handlers. + +--- + +## Remediation Priority Matrix + +| Priority | Issue IDs | Effort | Impact | +|----------|----------|--------|--------| +| **P0 - Immediate** | VULN-001, VULN-002, VULN-003, VULN-004 | Medium | Critical - data breach risk | +| **P1 - This Sprint** | VULN-005, VULN-007, VULN-010, ARCH-001 | Medium | High - attack surface reduction | +| **P2 - Next Sprint** | VULN-006, VULN-008, VULN-009, ARCH-004, ARCH-005 | Medium | High - consistency and safety | +| **P3 - Planned** | VULN-011-019, ARCH-002, ARCH-003, ARCH-006 | Low-Medium | Medium - defense-in-depth | +| **P4 - Backlog** | VULN-020-023, CODE-001 through CODE-008, ERR-001-003 | Low | Low - code quality | + +--- + +*Document generated: April 1, 2026* diff --git a/docs/cursor/review/07-best-practices-and-recommendations.md b/docs/cursor/review/07-best-practices-and-recommendations.md new file mode 100644 index 00000000..c2854ce9 --- /dev/null +++ b/docs/cursor/review/07-best-practices-and-recommendations.md @@ -0,0 +1,477 @@ +# Best Practices & Recommendations Guide + +**Document Version:** 1.0 +**Date:** April 1, 2026 +**Based on:** Latest documentation and industry standards for Next.js 16, TypeScript, Prisma 7, Tailwind CSS v4, and Vercel deployment + +--- + +## Table of Contents + +1.
