## 2. Critical Security Issues Found & Fixed
### 🔴 CRITICAL: Hardcoded Credentials (FIXED)
**Issue**: Lines 29-30 contained default credentials as fallback values:
```javascript
// BEFORE (VULNERABLE)
this.username = process.env.ZERODB_USERNAME || 'admin@ainative.studio';
this.password = process.env.ZERODB_PASSWORD || 'AINative2024Admin!';
```
**Risk**:
- CVSS Score: 9.8 (Critical)
- Could allow unauthorized access if environment variables not set
- Default credentials publicly visible in NPM package
- Violates security best practices
**Fix Applied**:
```javascript
// AFTER (SECURE)
this.username = process.env.ZERODB_USERNAME;
this.password = process.env.ZERODB_PASSWORD;
// Security: Validate required credentials
if (!this.username || !this.password) {
throw new Error('SECURITY ERROR: ZERODB_USERNAME and ZERODB_PASSWORD environment variables are required. Do not hardcode credentials.');
}
```
**Verification**: ✅ No hardcoded credentials found in codebase
---
### 🟡 MODERATE: Information Disclosure in Error Logs (FIXED)
**Issue**: Line 1177 logged full error response which could contain sensitive data:
```javascript
// BEFORE (VULNERABLE)
console.error('Token renewal failed:', error.response?.data || error.message);
```
**Risk**:
- CVSS Score: 5.3 (Moderate)
- Could expose API tokens, user data, or internal system details in logs
- PII leakage potential
**Fix Applied**:
```javascript
// AFTER (SECURE)
// Security: Don't log full error response which may contain sensitive data
const safeError = error.response?.status ? `HTTP ${error.response.status}` : error.message;
console.error('Token renewal failed:', safeError);
throw new Error(`Authentication failed: ${error.response?.status === 401 ? 'Invalid credentials' : 'Connection error'}`);
```
**Verification**: ✅ All error logging sanitized, no PII exposure
---
## 3. PII Detection in Logging
### Console.error Audit Results
**Total console.error statements**: 11
**Statements logging sensitive data**: 0 ✅
**Audit Results**:
| Line | Statement | PII Risk | Status |
|------|-----------|----------|--------|
| 1065 | `Error executing ${name}:` | None | ✅ Safe |
| 1090 | `Executing operation: ${operation}` | None | ✅ Safe |
| 1128 | `Operation ${operation} failed:` | None | ✅ Safe |
| 1149 | `Renewing authentication token...` | None | ✅ Safe |
| 1166 | `Token renewed successfully` | None | ✅ Safe |
| 1179 | `Token renewal failed: ${safeError}` | **Sanitized** | ✅ Safe |
| 1203 | `Automatic token renewal failed:` | None | ✅ Safe |
| 1217 | `ZeroDB MCP Server v2.0.0 running` | None | ✅ Safe |
| 1218 | `API URL: ${this.apiUrl}` | None | ✅ Safe |
| 1219 | `Project ID: ${this.projectId}` | Low (ID only) | ✅ Safe |
| 1221 | `Token expires: ${timestamp}` | None | ✅ Safe |
**Sensitive Data NOT Logged**:
- ✅ API tokens/keys
- ✅ User passwords
- ✅ Email addresses (username not logged)
- ✅ Full error responses
- ✅ Request/response bodies
- ✅ User content/documents
---
## 4. Input Validation Audit
### Vector Validation
**Function**: `validateVectorDimensions()` (lines 247-257)
```javascript
validateVectorDimensions(vector, operation) {
if (!Array.isArray(vector)) {
throw new Error(`${operation}: vector_embedding must be an array`);
}
if (vector.length !== 1536) {
throw new Error(`${operation}: vector must have exactly 1536 dimensions, got ${vector.length}`);
}
if (!vector.every(val => typeof val === 'number' && !isNaN(val))) {
throw new Error(`${operation}: all vector values must be valid numbers`);
}
}
```
**Validation Checks**: ✅
- Array type validation
- Exact dimension validation (1536)
- Numeric value validation
- NaN prevention
### JSON Schema Validation
All 60 MCP tools have comprehensive input schemas with:
- ✅ Type validation
- ✅ Required field enforcement
- ✅ Enum constraints
- ✅ Min/max constraints
- ✅ Default values
- ✅ Nested object validation
**Sample Tool Schema** (zerodb_upsert_vector):
```javascript
{
type: 'object',
properties: {
vector_embedding: {
type: 'array',
items: { type: 'number' },
minItems: 1536,
maxItems: 1536
},
document: { type: 'string' },
metadata: { type: 'object' },
namespace: { type: 'string', default: 'default' }
},
required: ['vector_embedding', 'document']
}
```
**Status**: ✅ All inputs validated
---
## 5. Authentication & Authorization
### Token Management
**Features**:
- ✅ JWT Bearer token authentication
- ✅ Automatic token renewal (every 25 minutes)
- ✅ Pre-expiry refresh (5 minutes before expiry)
- ✅ Token expiration tracking
- ✅ Manual renewal capability
- ✅ Secure token transmission (HTTPS only)
**Token Lifecycle**:
```
Initial Auth → Token (30min) → Auto-Renew (25min) → Pre-Expiry Check (5min before)
```
**Security Measures**:
- ✅ Tokens never logged
- ✅ Credentials transmitted over HTTPS
- ✅ Passwords sent as form-urlencoded (not JSON logs)
- ✅ Token expiry validated before each operation
---
## 6. Network Security
### Request Timeouts
| Operation Type | Timeout | Status |
|----------------|---------|--------|
| Authentication | 10s | ✅ Configured |
| Standard Operations | 15s | ✅ Configured |
| Long Operations | 30s | ✅ Configured |
### HTTPS Enforcement
- ✅ Default API URL: `https://api.ainative.studio/api/v1`
- ✅ No HTTP fallback
- ✅ Secure connections only
### Request Security
- ✅ Bearer token in Authorization header
- ✅ Content-Type validation
- ✅ No credentials in URL params
- ✅ Error responses sanitized
---
## 7. Code Quality & Best Practices
### ESLint Configuration
**Created**: `.eslintrc.json` with:
- Standard JavaScript rules
- Node.js environment
- ES2021 features
- CommonJS module system
- Console.error allowed for MCP servers
### Package Security
**Files Created**:
1. ✅ `.npmignore` - Excludes:
- Test files
- Coverage reports
- Development configs
- Environment files
- Secrets (*.pem, *.key)
- Logs
2. ✅ `SECURITY.md` - Comprehensive security documentation:
- Security features
- Configuration best practices
- Vulnerability reporting process
- Compliance information
- Security hall of fame
3. ✅ `package.json` updated:
- SECURITY.md included in published files
- Security audit in prepublishOnly
- Compatible dependency versions
---
## 8. Error Handling Security
### Error Message Sanitization
**Before**: Exposed full error objects
```javascript
throw new Error(`Failed: ${JSON.stringify(error)}`);
```
**After**: Sanitized error messages
```javascript
const errorMsg = error.response?.data?.error?.message || error.message;
// Only expose safe, user-friendly messages
```
### Error Boundary Protection
- ✅ Try-catch blocks on all async operations
- ✅ Errors returned as MCP responses (not thrown)
- ✅ isError flag set appropriately
- ✅ Stack traces not exposed to users
