fix: Improve plain text CV output with dedicated template
- Replace html2text library conversion with dedicated text template - Create clean, well-formatted cv-text.txt template - Remove k3a/html2text dependency - Fix lint warnings in security tests (ineffectual assignments) - Output now shows only CV content without UI/menu elements

# Contact Form Security Test Suite
|
||||
|
||||
Comprehensive security testing for the contact form API endpoint `/api/contact`.
|
||||
|
||||
## Test Files
|
||||
|
||||
### 1. `middleware_security_test.go` (Unit Tests)
|
||||
**Purpose**: Unit tests for security middleware in isolation
|
||||
**Test Coverage**:
|
||||
- ✅ Browser-Only Middleware (blocks curl, wget, Postman, etc.)
|
||||
- ✅ Referer/Origin header requirements
|
||||
- ✅ Browser-specific headers (HX-Request, X-Requested-With)
|
||||
- ✅ Rate limiting (5 requests per hour per IP)
|
||||
- ✅ Security headers (CSP, X-Frame-Options, etc.)
|
||||
- ✅ Attack scenario simulations
|
||||
|
||||
**Run Tests**:
|
||||
```bash
|
||||
# Run all tests
|
||||
go test -v ./tests/security/middleware_security_test.go
|
||||
|
||||
# Run with coverage
|
||||
go test -cover ./tests/security/middleware_security_test.go
|
||||
|
||||
# Run benchmarks
|
||||
go test -bench=. -benchmem ./tests/security/middleware_security_test.go
|
||||
```
|
||||
|
||||
**Performance** (Apple M3 Pro):
|
||||
- BrowserOnly Middleware: **2,350 ns/op** (~425,000 requests/sec)
|
||||
- Rate Limiter: **2,401 ns/op** (~416,000 requests/sec)
|
||||
- Full Security Chain: **3,110 ns/op** (~321,000 requests/sec)
|
||||
|
||||
### 2. `contact_security_test.go` (Integration Tests)
|
||||
**Purpose**: End-to-end integration tests with full handler chain
|
||||
**Test Coverage**:
|
||||
- ✅ Complete security middleware integration
|
||||
- ✅ Form validation (email format, message length)
|
||||
- ✅ Bot protection (honeypot field, timing checks)
|
||||
- ✅ Rate limiting across full stack
|
||||
- ✅ Required fields validation
|
||||
|
||||
**Note**: Some tests may show email sending errors in test environment (expected behavior - we're testing security layers, not email delivery).
|
||||
|
||||
**Run Tests**:
|
||||
```bash
|
||||
go test -v ./tests/security/contact_security_test.go
|
||||
```
|
||||
|
||||
### 3. `security_tests.sh` (Live Server Tests)
|
||||
**Purpose**: Black-box testing against running server
|
||||
**Test Coverage**:
|
||||
- ✅ Real HTTP client blocking (curl, wget, Postman, Python)
|
||||
- ✅ Header validation in production environment
|
||||
- ✅ Email format validation
|
||||
- ✅ Message length limits
|
||||
- ✅ Honeypot bot detection
|
||||
- ✅ Form submission timing
|
||||
- ✅ Rate limiting enforcement
|
||||
- ✅ Attack scenario testing
|
||||
|
||||
**Run Tests**:
|
||||
```bash
|
||||
# Start your server first
|
||||
go run main.go
|
||||
|
||||
# In another terminal, run tests
|
||||
./tests/security/security_tests.sh http://localhost:1999
|
||||
|
||||
# Or test production
|
||||
./tests/security/security_tests.sh https://yourdomain.com
|
||||
```
|
||||
|
||||
## Security Features Tested
|
||||
|
||||
### 1. Browser-Only Access
|
||||
**Protection**: Blocks non-browser HTTP clients
|
||||
**Blocks**:
|
||||
- curl (User-Agent: `curl/*`)
|
||||
- wget (User-Agent: `Wget/*`)
|
||||
- Postman (User-Agent: `PostmanRuntime/*`)
|
||||
- Python requests (User-Agent: `python-requests/*`)
|
||||
- Insomnia, HTTPie, Go http client, etc.
|
||||
|
||||
**Requires**:
|
||||
- Valid browser User-Agent header
|
||||
- Referer OR Origin header
|
||||
- Browser-specific header (HX-Request, X-Requested-With, or X-Browser-Request)
|
||||
|
||||
### 2. Input Validation
|
||||
**Email Format**:
|
||||
- ✅ Must contain @ and domain with TLD
|
||||
- ✅ Max 254 characters
|
||||
- ✅ No newlines (header injection protection)
|
||||
|
||||
**Message Validation**:
|
||||
- ✅ Minimum 10 characters
|
||||
- ✅ Maximum 5,000 characters
|
||||
- ✅ Required field
|
||||
|
||||
**Other Fields**:
|
||||
- Name: Max 100 chars, letters/spaces/hyphens/apostrophes only
|
||||
- Company: Max 100 chars (optional)
|
||||
- Subject: Max 200 chars
|
||||
|
||||
### 3. Bot Protection
|
||||
|
||||
**Honeypot Field**:
|
||||
- Hidden `website` field must be empty
|
||||
- If filled, bot is detected but receives fake 200 success (to fool automated bots)
|
||||
|
||||
**Timing Validation**:
|
||||
- Form must be displayed for ≥2 seconds before submission
|
||||
- Too fast (<2s): Rejected as bot
|
||||
- Normal (≥2s): Allowed
|
||||
|
||||
### 4. Rate Limiting
|
||||
**Limits**: 5 requests per hour per IP address
|
||||
**Enforcement**: 6th request returns 429 Too Many Requests
|
||||
**Tracking**: Per IP address (handles X-Forwarded-For for proxies)
|
||||
|
||||
### 5. Security Headers
|
||||
All responses include:
|
||||
- `X-Content-Type-Options: nosniff`
|
||||
- `X-Frame-Options: SAMEORIGIN`
|
||||
- `X-XSS-Protection: 1; mode=block`
|
||||
- `Referrer-Policy: strict-origin-when-cross-origin`
|
||||
- `Content-Security-Policy: ...` (comprehensive CSP)
|
||||
- `Permissions-Policy: ...` (restrictive)
|
||||
- `Strict-Transport-Security` (production only with HTTPS)
|
||||
|
||||

|
||||
```
|
||||
|
||||
## Attack Scenarios Tested
|
||||
|
||||
### Scenario 1: Script Kiddie with curl
|
||||
**Attack**: Direct curl request
|
||||
```bash
|
||||
curl -X POST /api/contact -d "email=hacker@evil.com&message=Pwned"
|
||||
```
|
||||
**Result**: ❌ Blocked 403 Forbidden (no browser User-Agent)
|
||||
|
||||
### Scenario 2: Sophisticated Bot
|
||||
**Attack**: Bot with browser-like headers but fills honeypot
|
||||
```bash
|
||||
curl -X POST /api/contact \
|
||||
-H "User-Agent: Mozilla/5.0" \
|
||||
-H "Referer: http://target.com/" \
|
||||
-H "HX-Request: true" \
|
||||
-d "website=http://spam.com&..."
|
||||
```
|
||||
**Result**: ✅ Returns fake 200 (bot fooled), email not sent
|
||||
|
||||
### Scenario 3: Automated Form Filler
|
||||
**Attack**: Script that fills form instantly (<2s)
|
||||
```bash
|
||||
curl -X POST /api/contact \
|
||||
-H "User-Agent: Mozilla/5.0" \
|
||||
-H "Referer: http://target.com/" \
|
||||
-H "HX-Request: true" \
|
||||
-d "submit_time=<500ms ago>&..."
|
||||
```
|
||||
**Result**: ❌ Blocked 400 Bad Request (too fast)
|
||||
|
||||
### Scenario 4: Postman/API Client
|
||||
**Attack**: Postman without proper headers
|
||||
```bash
|
||||
curl -H "User-Agent: PostmanRuntime/7.26.8" ...
|
||||
```
|
||||
**Result**: ❌ Blocked 403 Forbidden (non-browser client)
|
||||
|
||||
### Scenario 5: Email Header Injection
|
||||
**Attack**: Malicious newlines in subject
|
||||
```bash
|
||||
curl -d "subject=Test%0AContent-Type:%20text/html&..." ...
|
||||
```
|
||||
**Result**: ❌ Blocked 400 Bad Request (validation error)
|
||||

## Maintenance
|
||||
|
||||
### Adding New Security Tests
|
||||
|
||||
1. **Unit Test** (for new middleware):
|
||||
- Add test in `middleware_security_test.go`
|
||||
- Follow existing pattern (Arrange-Act-Assert)
|
||||
- Add benchmark if performance-critical
|
||||
|
||||
2. **Integration Test** (for new validation):
|
||||
- Add test in `contact_security_test.go`
|
||||
- Test with full handler chain
|
||||
|
||||
3. **Live Test** (for black-box validation):
|
||||
- Add function in `security_tests.sh`
|
||||
- Follow existing format with colored output
|
||||
- Update test counter
|
||||
|
||||
### Security Checklist for Code Reviews
|
||||
- [ ] New middleware added to middleware_security_test.go
|
||||
- [ ] Integration tests updated if handler changes
|
||||
- [ ] Live tests updated if API contract changes
|
||||
- [ ] All tests pass (`go test ./tests/security/...`)
|
||||
- [ ] Benchmarks run (<5ms per request)
|
||||
- [ ] Documentation updated
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Server Not Running Error
|
||||
```bash
|
||||
✗ Server is not accessible at http://localhost:8080
|
||||
Please start the server first: go run main.go
|
||||
```
|
||||
**Solution**: Start server in separate terminal before running shell tests
|
||||
|
||||
### Permission Denied on Shell Script
|
||||
```bash
|
||||
permission denied: ./security_tests.sh
|
||||
```
|
||||
**Solution**: Make script executable
|
||||
```bash
|
||||
chmod +x ./tests/security/security_tests.sh
|
||||
```
|
||||
|
||||
### Rate Limit Test Failures
|
||||
If rate limit tests fail intermittently:
|
||||
- Tests share the same rate limiter instance
|
||||
- Wait 1 hour between test runs, or
|
||||
- Restart the test server to reset limits
|
||||
|
||||
