## Security Features
13+
14+
### Current Security Measures
15+
16+
- **Environment Variable Validation**: All required environment variables are validated on startup
17+
- **Secure CORS Configuration**: Environment-specific CORS settings with restrictive production defaults
18+
- **Rate Limiting**: Comprehensive rate limiting for different endpoint types
19+
- **Input Validation**: All user inputs are sanitized and validated
20+
- **Secure File Uploads**: File type validation, size limits, and content verification
21+
- **Error Handling**: Secure error responses that prevent information disclosure
22+
- **Authentication**: JWT-based authentication with proper token validation
23+

24+
- **Dependency Security**: Regular npm audit checks and automatic fixes
25+
26+
### Security Headers
27+
28+
The application automatically sets the following security headers:
29+
30+
- `X-Content-Type-Options: nosniff`
31+
- `X-Frame-Options: DENY`
32+
- `X-XSS-Protection: 1; mode=block`
33+
- `Strict-Transport-Security` (in production)
34+
35+
### Rate Limiting
36+
37+
Different endpoints have different rate limits:
38+
39+
- **General API**: 100 requests per 15 minutes
40+
- **Authentication**: 5 requests per 15 minutes
41+
- **Voice API**: 10 requests per 5 minutes
42+
- **File Uploads**: 5 requests per 10 minutes
43+
- **Emergency APIs**: 20 requests per minute

# Security Audit Report - SafeEscape Backend
2+
3+
## Executive Summary
4+
This report documents the security audit conducted on the SafeEscape backend application, identifying critical security vulnerabilities and providing fixes for each issue.
5+
6+
## Critical Security Issues Identified
7+
8+
### 1. **CRITICAL: Missing JWT Secret Environment Variable**
9+
**Severity**: Critical
10+
**Location**: `middleware/auth/auth.js:10`
11+
**Issue**: The application uses `process.env.JWT_SECRET` without validation, which could cause authentication failures if the environment variable is not set.
12+
**Risk**: Authentication bypass, application crashes
13+
14+
### 2. **HIGH: Overly Permissive CORS Configuration**
15+
**Severity**: High
16+
**Location**: `server.js:72`, `server-core.js:37`, `bot/app.js:16`
17+
**Issue**: CORS is configured with `origin: '*'` allowing any domain to make requests
18+
**Risk**: Cross-origin attacks, data theft
19+
20+
### 3. **HIGH: Missing Input Validation**
21+
**Severity**: High
22+
**Location**: Multiple route handlers
23+
**Issue**: No input validation on request bodies, params, or query parameters
24+
**Risk**: Injection attacks, data corruption
25+
26+
### 4. **HIGH: Unsafe JSON.parse() Usage**
27+
**Severity**: High
28+
**Location**: Multiple files including `config/firebase-config.js:23`
29+
**Issue**: JSON.parse() used without try-catch blocks in several places
30+
**Risk**: Application crashes, DoS attacks
31+
32+
### 5. **MEDIUM: Missing Rate Limiting**
33+
**Severity**: Medium
34+
**Location**: Server configuration
35+
**Issue**: No rate limiting implemented despite express-rate-limit being installed
36+
**Risk**: DoS attacks, resource exhaustion
37+
38+
### 6. **MEDIUM: Information Disclosure in Error Messages**
39+
**Severity**: Medium
40+
**Location**: `server.js:254`, error handlers
41+
**Issue**: Detailed error messages exposed in production
42+
**Risk**: Information leakage
43+
44+
### 7. **MEDIUM: Insecure File Upload Configuration**
45+
**Severity**: Medium
46+
**Location**: `bot/app.js:30`, `routes/aiRoutes.js:4`
47+
**Issue**: File uploads without proper validation and sanitization
48+
**Risk**: Malicious file uploads, path traversal
49+
50+
### 8. **LOW: Excessive Console Logging**
51+
**Severity**: Low
52+
**Location**: Multiple files
53+
**Issue**: Sensitive information logged to console
54+
**Risk**: Information disclosure in logs
55+
56+
