## 1. SECURITY ISSUES

### Critical Issues

#### 1.1 **Axios SSRF Vulnerability** [CRITICAL]
- **Severity:** CRITICAL
- **Issue:** Axios has a NO_PROXY Hostname Normalization Bypass leading to SSRF
- **Affected Package:** `axios < 1.15.0` (via `typesense > axios`)
- **Path:** `apps__api > typesense > axios`
- **Risk:** Server-side request forgery attacks possible
- **Recommendation:** 
  - Update typesense dependency to use axios >= 1.15.0
  - Pin axios version explicitly in package.json

#### 1.2 **Next.js HTTP Request Deserialization DoS** [HIGH]
- **Severity:** HIGH
- **Issue:** Next.js < 15.0.8 vulnerable to DoS when using insecure React Server Components
- **Affected Package:** `next ^14.2.0` (apps/web/package.json:33)
- **Current Version:** 14.2.0 (vulnerable)
- **Recommendation:**
  - Upgrade to Next.js ^15.0.8
  - Test compatibility before production deployment

#### 1.3 **Lodash Code Injection & Prototype Pollution** [HIGH]
- **Severity:** HIGH
- **Issues:** Two vulnerabilities in lodash <= 4.17.23
  1. Code Injection via `_.template` imports
  2. Prototype Pollution via `_.unset` and `_.omit`
- **Affected Path:** `apps__api > @nestjs/config > lodash`
- **Recommendation:**
  - Update @nestjs/config to use lodash >= 4.18.0
  - Check if lodash can be removed or replaced with native JS

#### 1.4 **path-to-regexp DoS Vulnerabilities** [HIGH]
- **Severity:** HIGH
- **Issues:** Two DoS vulnerabilities (sequential optional groups, regex DoS)
- **Affected Path:** `apps__api > @nestjs/swagger > path-to-regexp`
- **Current Version:** < 8.4.0 (vulnerable)
- **Recommendation:**
  - Update @nestjs/swagger to use path-to-regexp >= 8.4.0

### High Priority Issues

#### 1.5 **Next.js Image Optimizer Issues** [MODERATE/HIGH]
- **Issues (3):**
  1. DoS via remotePatterns configuration (< 15.5.10)
  2. HTTP request smuggling in rewrites (< 15.5.13)
  3. Unbounded disk cache growth (< 15.5.14)
- **Current Version:** 14.2.0 (all vulnerable)
- **Recommendation:** Upgrade to Next.js ^15.5.14

### Medium Priority Issues

#### 1.6 **Moderate Vulnerabilities** [MODERATE]
- `@hono/node-server < 1.19.13`: Middleware bypass via repeated slashes
- `@tootallnate/once < 3.0.1`: Incorrect control flow scoping
- Multiple Next.js vulnerabilities affecting image and request handling

**Total Dependencies with Issues:** 6 packages
**Action Required:** 6 high/critical issues MUST be fixed before production

---

## 2. SECURITY BEST PRACTICES ✅

### Positive Findings

✅ **Environment Configuration:**
- `.env` is NOT committed to git (correctly listed in `.gitignore`)
- `.env.example` exists with template values (71 environment variables documented)
- `.env.test` provided for test environment
- No hardcoded secrets found in TypeScript code

✅ **API Security Headers (apps/api/src/main.ts):**
- Helmet.js configured with strong CSP directives
- CORS properly enforced with environment variable validation
- Production CORS requires `CORS_ORIGINS` to be set
- HSTS, X-Frame-Options, Permissions-Policy configured
- Cookie parser for CSRF protection
- Rate limiting trust proxy configuration

✅ **CI/CD Security:**
- E2E tests use separate CI credentials (not production)
- Test database password safely isolated
- JWT secrets in CI are test-only values

### Remaining Gaps

⚠️ **Typesense CORS:**
- Line 50 in `docker-compose.yml`: `TYPESENSE_ENABLE_CORS: 'true'` (acceptable for dev)
- Recommendation: Disable in production or restrict origins

⚠️ **Password Storage:**
- Production secrets use Docker secrets manager (good)
- Grafana admin credentials properly isolated
- Recommendation: Ensure all production secrets use secrets manager

## 3. TEST COVERAGE ANALYSIS

### Summary Statistics
- **Total Source Files:** 557 (API: 509, Frontend: 48)
- **Total Test Files:** 166 (API: 166, Frontend: 0)
- **Overall Coverage Ratio:** 30% (166 tests / 557 sources)

| **analytics** | 49 | 18 | 37% | 🟠 MEDIUM |
| **auth** | 72 | 21 | 29% | 🔴 LOW |
| **health** | 5 | 3 | 60% | 🟢 GOOD |
| **inquiries** | 19 | 5 | 26% | 🔴 LOW |
| **leads** | 23 | 6 | 26% | 🔴 LOW |
| **listings** | 55 | 13 | 24% | 🔴 LOW |
| **mcp** | 3 | 1 | 33% | 🟠 MEDIUM |
| **metrics** | 7 | 2 | 28% | 🔴 LOW |
| **notifications** | 32 | 17 | 53% | 🟡 FAIR |

| **shared** | 38 | 18 | 47% | 🟡 FAIR |
| **subscriptions** | 35 | 13 | 37% | 🟠 MEDIUM |

### High Priority Coverage Gaps

**CRITICAL:** Modules with <30% coverage:
- `listings` (24%): 55 sources, only 13 tests — core business logic
- `leads` (26%): 23 sources, only 6 tests
- `inquiries` (26%): 19 sources, only 5 tests
- `search` (30%): 33 sources, only 10 tests
- `auth` (29%): 72 sources, only 21 tests — security-critical

### Reviews Controller Test Status

**File:** `apps/api/src/modules/reviews/presentation/__tests__/reviews.controller.spec.ts`
- ✅ Status: **Tests Pass** (not failing)
- Coverage: 100% of controller methods tested
  - ✅ `createReview` with/without comment (lines 21-49)
  - ✅ `getReviewsByTarget` with defaults and custom params (lines 52-80)
  - ✅ `getStats` for average rating (lines 83-98)
  - ✅ `getMyReviews` (lines 101-116)
  - ✅ `deleteReview` (lines 119-133)
- Note: Test uses mocked buses; handler logic not fully tested

### Frontend Test Coverage
- **Frontend source files:** 48 `.tsx` files
- **Frontend test files:** 0 (No tests in `apps/web/`)
- **Status:** 🔴 CRITICAL GAP
- **Recommendation:** Add vitest configuration and tests for critical UI components

## 5. MISSING SPRINT FEATURES FROM BLUEPRINT

### Sprint Item Implementation Status

| Feature | Status | Evidence | Priority |
|---------|--------|----------|----------|
| **Saved Searches + Alerts** | ❌ NOT IMPLEMENTED | No SavedSearch entity, handlers, or routes found | HIGH |
| **Transaction Flow (Inquiry→Deposit→Complete)** | ❌ NOT IMPLEMENTED | Deposit logic not found in payments or inquiries modules | HIGH |
| **Agent Quality Score Calculation** | ✅ IMPLEMENTED | `apps/api/src/modules/agents/` has quality score calculation, recalculation handler, and event listener (review-based) | DONE |
| **Mobile App Preparation** | ✅ PARTIALLY IMPLEMENTED | FCM push notifications configured (`fcm.service.ts`), API versioning ready for mobile, but no mobile app repo found | IN-PROGRESS |
| **Agent Cooperation Network** | ❌ NOT IMPLEMENTED | No cooperation network entities, referral system, or network features in agents module | HIGH |

### Implementation Details

**Agent Quality Score:** ✅ Working
- File: `apps/api/src/modules/agents/domain/__tests__/quality-score.spec.ts`
- Handler: `recalculate-quality-score.handler.ts`
- Listener: `review-events.listener.ts` (updates score on review creation/deletion)
- Dashboard: `get-agent-dashboard.handler.ts` includes score data

**Missing Critical Features:**
1. **Saved Searches:** Would require:
   - SavedSearch entity in Prisma schema
   - Search/Queries/SavedSearchQuery handler
   - Commands/SaveSearchCommand, Commands/DeleteSavedSearchCommand
   - Alerts system for price changes or new listings

2. **Deposit Transaction Flow:** Would require:
   - Deposit entity for escrow/payment holds
   - Transaction state machine (pending → completed → released)
   - Integration with payment gateways (VNPay, MoMo, ZaloPay)
   - Currently only has generic payments module

3. **Agent Cooperation Network:** Would require:
   - Agent referral/relationship entities
   - Network topology storage
   - Incentive/commission calculation
   - Network analytics
