# LiveComponents Security Audit Report
|
||
|
||
**Sprint**: Sprint 2 - Security Audit & OWASP Top 10 Check
|
||
**Date**: 2025-10-19
|
||
**System**: LiveComponents Framework Module
|
||
**Auditor**: Claude Code
|
||
**Duration**: 5-7 days (In Progress)
|
||
|
||
---
|
||
|
||
## Executive Summary
|
||
|
||
### Overall Security Posture: **STRONG** (B+ Grade)
|
||
|
||
The LiveComponents system demonstrates a **defense-in-depth security architecture** with multiple layers of protection. The implementation follows security best practices with:
|
||
|
||
- ✅ **6 major security layers** implemented and active
|
||
- ✅ **Framework-first security** - Security built into core architecture
|
||
- ✅ **Type-safe validation** - Readonly Value Objects prevent state tampering
|
||
- ✅ **Explicit allow-lists** - `#[Action]` attribute required for all callable methods
|
||
- ⚠️ **Encryption gap** - Sensitive state data not encrypted at rest
|
||
- ⚠️ **Testing coverage** - Security components need comprehensive unit tests
|
||
|
||
**Risk Level**: **LOW-MEDIUM** - System is production-ready with recommended improvements.

## OWASP Top 10:2021 Coverage Analysis
|
||
|
||
### A01:2021 – Broken Access Control ✅ COVERED
|
||
|
||
**Status**: **STRONG** - Multi-layer access control implementation
|
||
|
||
**Implemented Controls**:
|
||
|
||
1. **Permission-Based Authorization** (`ActionAuthorizationChecker`)
|
||
- Interface-based authorization system
|
||
- `#[RequiresPermission]` attribute for action-level access control
|
||
- Session-based implementation with `isAuthorized()` checks
|
||
- Method: `isAuthorized(component, method, permissionAttribute)`
|
||
|
||
2. **Action Allow-List** (`validateAction()` in `LiveComponentHandler`)
|
||
- Explicit `#[Action]` attribute required for all callable methods
|
||
- Reserved method protection (render, mount, hydrate, dehydrate)
|
||
- Public method + non-static validation
|
||
- Return type validation (must return State object)
|
||
|
||
3. **CSRF Protection** (Per-Component-Instance)
|
||
- Token required for all state-changing actions
|
||
- Component-scoped tokens: `livecomponent:{componentId}`
|
||
- Session-based CSRF validation
|
||
- Automatic token injection via `CsrfTokenProcessor`
|
||
|
||
**Code Evidence**:
|
||
```php
|
||
// Authorization check in LiveComponentHandler
|
||
private function validateAuthorization(
|
||
LiveComponentContract $component,
|
||
string $method
|
||
): void {
|
||
$reflection = new \ReflectionMethod($component, $method);
|
||
$permissionAttributes = $reflection->getAttributes(RequiresPermission::class);
|
||
|
||
if (empty($permissionAttributes)) {
|
||
return; // No permission required
|
||
}
|
||
|
||
$permissionAttribute = $permissionAttributes[0]->newInstance();
|
||
|
||
if (! $this->authorizationChecker->isAuthorized($component, $method, $permissionAttribute)) {
|
||
throw new UnauthorizedActionException(
|
||
"User does not have permission to execute action '{$method}'"
|
||
);
|
||
}
|
||
}
|
||
|
||
// Action validation with explicit allow-list
|
||
private function validateAction(LiveComponentContract $component, string $method): ?Action
|
||
{
|
||
if (ReservedActionName::isReserved($method)) {
|
||
throw new \BadMethodCallException("Cannot call reserved method '{$method}'");
|
||
}
|
||
|
||
$reflection = new \ReflectionMethod($component, $method);
|
||
$actionAttributes = $reflection->getAttributes(Action::class);
|
||
|
||
if (empty($actionAttributes)) {
|
||
throw new \BadMethodCallException(
|
||
"Method '{$method}' is not marked as an action. Add #[Action] attribute"
|
||
);
|
||
}
|
||
|
||
return $actionAttributes[0]->newInstance();
|
||
}
|
||
```
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Strong access control with defense-in-depth
|
||
|
||
**Recommendations**:
|
||
- ✅ Already implemented - No critical gaps
|
||
- Consider: Add audit logging for authorization failures
|
||
- Consider: Implement role-based access control (RBAC) for complex permission scenarios
|
||

|
||
|
||
### A02:2021 – Cryptographic Failures ⚠️ PARTIAL COVERAGE
|
||
|
||
**Status**: **NEEDS IMPROVEMENT** - Encryption missing for sensitive state data
|
||
|
||
**Implemented Controls**:
|
||
|
||
1. **Session Security**
|
||
- Session-based CSRF tokens (cryptographically secure)
|
||
- Client identifier hashing: `Hash::sha256($identifier->toString())->toShort(16)`
|
||
|
||
**Missing Controls**:
|
||
|
||
1. ❌ **State Encryption at Rest**
|
||
- Sensitive state data (user PII, payment info) stored unencrypted
|
||
- No encryption layer for `StateSnapshot` storage
|
||
- Search result: `grep -r "encrypt" src/Framework/LiveComponents/` returned **0 results**
|
||
|
||
2. ❌ **Transport Layer Security Documentation**
|
||
- No explicit HTTPS enforcement in LiveComponents layer
|
||
- Relies on application-level configuration
|
||
|
||
**Risk Assessment**: ⚠️ **MEDIUM** - Sensitive data exposure risk
|
||
|
||
**Recommendations**:
|
||
|
||
**Priority 1 - HIGH**: Implement State Encryption Layer
|
||
```php
|
||
// Recommended implementation
|
||
final readonly class EncryptedStateSerializer implements StateSerializer
|
||
{
|
||
public function __construct(
|
||
private readonly Encryptor $encryptor,
|
||
private readonly StateSerializer $innerSerializer
|
||
) {}
|
||
|
||
public function serialize(object $state): string
|
||
{
|
||
$plaintext = $this->innerSerializer->serialize($state);
|
||
|
||
// Encrypt sensitive state data
|
||
return $this->encryptor->encrypt($plaintext);
|
||
}
|
||
|
||
public function deserialize(string $serialized, string $className): object
|
||
{
|
||
$plaintext = $this->encryptor->decrypt($serialized);
|
||
|
||
return $this->innerSerializer->deserialize($plaintext, $className);
|
||
}
|
||
}
|
||
|
||
// Usage in LiveComponentHandler
|
||
$encryptedSerializer = new EncryptedStateSerializer(
|
||
encryptor: $this->vault->getEncryptor(),
|
||
innerSerializer: $this->stateSerializer
|
||
);
|
||
```
|
||
|
||
**Priority 2 - MEDIUM**: Add HTTPS Enforcement Middleware
|
||
- Document HTTPS requirement in production deployment checklist
|
||
- Add middleware to enforce HTTPS for LiveComponent requests
|
||
- Implement HSTS headers
|
||
|
||
---
|
||
|
||
### A03:2021 – Injection ✅ STRONG COVERAGE
|
||
|
||
**Status**: **EXCELLENT** - Multiple injection protection layers
|
||
|
||
**Implemented Controls**:
|
||
|
||
1. **Type-Safe State Validation** (`DefaultStateValidator`)
|
||
- Automatic schema derivation from readonly Value Objects
|
||
- Type checking: `$this->typesMatch($expectedType, $actualType, $value)`
|
||
- Field validation: Required fields, unexpected fields, type mismatches
|
||
- Throws `StateValidationException` on validation failure
|
||
|
||
2. **Readonly Value Objects** (Framework Principle)
|
||
- All state represented as immutable Value Objects
|
||
- No direct SQL queries in LiveComponents layer
|
||
- State changes only via validated action methods
|
||
|
||
3. **Action Parameter Validation**
|
||
- Return type validation (must return State object, not primitive types)
|
||
- Public method + non-static validation
|
||
- Prevents void/null/int/float/string/bool/array returns
|
||
|
||
**Code Evidence**:
|
||
```php
|
||
// Type-safe state validation
|
||
public function checkState(object $state, DerivedSchema $schema): ValidationResult
|
||
{
|
||
$errors = [];
|
||
$fieldErrors = [];
|
||
$stateData = $state->toArray();
|
||
|
||
// Check for missing required fields
|
||
foreach ($schema->getFields() as $field) {
|
||
if (! array_key_exists($field, $stateData)) {
|
||
if (! $schema->isNullable($field)) {
|
||
$fieldErrors[$field] = "Field '{$field}' is missing but required";
|
||
}
|
||
}
|
||
}
|
||
|
||
// Check for unexpected fields and type mismatches
|
||
foreach ($stateData as $field => $value) {
|
||
if (! $schema->hasField($field)) {
|
||
$fieldErrors[$field] = "Field '{$field}' is not in schema";
|
||
continue;
|
||
}
|
||
|
||
$expectedType = $schema->getType($field);
|
||
$actualType = $this->getValueType($value);
|
||
|
||
if (! $this->typesMatch($expectedType, $actualType, $value)) {
|
||
$fieldErrors[$field] = "Field expects '{$expectedType}' but got '{$actualType}'";
|
||
}
|
||
}
|
||
|
||
return empty($errors) && empty($fieldErrors)
|
||
? ValidationResult::valid()
|
||
: ValidationResult::invalid($errors, $fieldErrors);
|
||
}
|
||
```
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Strong injection protection through type system
|
||
|
||
**Recommendations**:
|
||
- ✅ Already implemented - No critical gaps
|
||
- Consider: Add XSS protection documentation for template rendering
|
||
- Consider: Document SQL injection protection at framework database layer
|
||
|
||
---
|
||
|
||
### A04:2021 – Insecure Design ✅ EXCELLENT
|
||
|
||
**Status**: **BEST IN CLASS** - Security-first architecture
|
||
|
||
**Implemented Design Patterns**:
|
||
|
||
1. **Defense in Depth** (6 Security Layers)
|
||
```
|
||
Request → CSRF Validation → Action Validation → Idempotency Check
|
||
→ Rate Limiting → Authorization → State Validation → Execute
|
||
```
|
||
|
||
2. **Principle of Least Privilege**
|
||
- Explicit `#[Action]` attribute required (deny by default)
|
||
- Permission-based authorization with `#[RequiresPermission]`
|
||
- Reserved methods blocked from external calls
|
||
|
||
3. **Fail Securely**
|
||
- Invalid CSRF token → Exception + Block
|
||
- Missing `#[Action]` → Exception + Block
|
||
- Rate limit exceeded → Exception + 429 Response
|
||
- Unauthorized → Exception + 403 Response
|
||
- Invalid state → Exception + Rollback
|
||
|
||
4. **Immutable State Architecture**
|
||
- Readonly Value Objects prevent state tampering
|
||
- State changes only via validated action methods
|
||
- No direct property mutation allowed
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Excellent security architecture
|
||
|
||
**Recommendations**:
|
||
- ✅ Already implemented - Framework follows security best practices
|
||
- Consider: Document security design decisions in architecture docs
|
||
- Consider: Create threat model diagram for LiveComponents request flow
|
||
|
||

|
||
|
||
### A05:2021 – Security Misconfiguration ✅ GOOD
|
||
|
||
**Status**: **GOOD** - Secure defaults with configuration flexibility
|
||
|
||
**Implemented Secure Defaults**:
|
||
|
||
1. **Rate Limiting Defaults** (`LiveComponentRateLimiter`)
|
||
- Action-level default: **30 requests/minute**
|
||
- Component-level default: **60 requests/minute**
|
||
- 1-minute sliding window
|
||
- Per-client identifier isolation
|
||
|
||
2. **CSRF Protection**
|
||
- Enabled by default for all actions
|
||
- No opt-out mechanism (always required)
|
||
- Per-component-instance token scope
|
||
|
||
3. **Authorization**
|
||
- Default: No permission required (public access)
|
||
- Explicit opt-in via `#[RequiresPermission]` attribute
|
||
- Session-based authentication
|
||
|
||
**Code Evidence**:
|
||
```php
|
||
private function getDefaultActionLimit(): ?int
|
||
{
|
||
return 30; // 30 requests per minute per action
|
||
}
|
||
|
||
private function getDefaultComponentLimit(): int
|
||
{
|
||
return 60; // 60 requests per minute for all actions combined
|
||
}
|
||
```
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Secure defaults in place
|
||
|
||
**Recommendations**:
|
||
|
||
**Priority 1 - MEDIUM**: Document Production Security Configuration
|
||
- Create `docs/livecomponents/security-deployment.md` with:
|
||
- Rate limiting configuration recommendations
|
||
- HTTPS enforcement checklist
|
||
- Security headers configuration
|
||
- Session security settings
|
||
|
||
**Priority 2 - LOW**: Add Security Configuration Validation
|
||
```php
|
||
final readonly class LiveComponentSecurityValidator
|
||
{
|
||
public function validateProductionConfig(LiveComponentConfig $config): SecurityValidationReport
|
||
{
|
||
$issues = [];
|
||
|
||
// Check rate limiting is enabled
|
||
if ($config->rateLimitingEnabled === false) {
|
||
$issues[] = "Rate limiting should be enabled in production";
|
||
}
|
||
|
||
// Check default limits are reasonable
|
||
if ($config->defaultActionLimit > 100) {
|
||
$issues[] = "Default action limit is too high (>100/min)";
|
||
}
|
||
|
||
// Check HTTPS enforcement
|
||
if (! $config->requireHttps) {
|
||
$issues[] = "HTTPS should be enforced in production";
|
||
}
|
||
|
||
return new SecurityValidationReport($issues);
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### A06:2021 – Vulnerable and Outdated Components 🔄 TO BE ASSESSED
|
||
|
||
**Status**: **PENDING** - Automated dependency scanning required
|
||
|
||
**Current State**:
|
||
- PHP 8.5.0RC2 (Docker container)
|
||
- Composer dependencies not yet scanned
|
||
- JavaScript dependencies (Vite, frontend) not yet scanned
|
||
|
||
**Risk Assessment**: ⚠️ **UNKNOWN** - Requires automated scanning
|
||
|
||
**Recommendations**:
|
||
|
||
**Priority 1 - HIGH**: Sprint 2 Task 4 - Automated Dependency Scanning (1-2 days)
|
||
- Implement Composer dependency scanning
|
||
- Implement NPM dependency scanning
|
||
- Set up continuous monitoring
|
||
|
||
**Planned Tools**:
|
||
1. **PHP Dependencies**: `composer audit` + Roave Security Advisories
|
||
2. **JavaScript Dependencies**: `npm audit`
|
||
3. **CI/CD Integration**: Automated vulnerability scanning in build pipeline
|
||
|
||
**Action Required**: Execute Sprint 2 Task 4 after completing security audit
|
||
|
||
---
|
||
|
||
### A07:2021 – Identification and Authentication Failures ✅ COVERED
|
||
|
||
**Status**: **GOOD** - Session-based authentication with security controls
|
||
|
||
**Implemented Controls**:
|
||
|
||
1. **Rate Limiting Protection** (Brute Force Prevention)
|
||
- 30 requests/minute per action default
|
||
- 60 requests/minute per component default
|
||
- Client identifier hashing for privacy
|
||
- Configurable per-action limits via `#[Action]` attribute
|
||
|
||
2. **Idempotency Protection** (Replay Attack Prevention)
|
||
- Optional per-action idempotency with TTL
|
||
- Prevents duplicate request processing
|
||
- Integrated with `IdempotencyService`
|
||
- Configurable TTL: `idempotencyTTL: Duration::fromMinutes(5)`
|
||
|
||
3. **Session-Based Authentication**
|
||
- `SessionBasedAuthorizationChecker` implementation
|
||
- `isAuthenticated()` check available
|
||
- `getUserPermissions()` for fine-grained access control
|
||
|
||
**Code Evidence**:
|
||
```php
|
||
// Idempotency protection in LiveComponentHandler
|
||
if ($params->hasIdempotencyKey() && $actionAttribute?->idempotencyTTL !== null) {
|
||
return $this->handleWithIdempotency($component, $method, $params, $actionAttribute);
|
||
}
|
||
|
||
private function handleWithIdempotency(
|
||
LiveComponentContract $component,
|
||
string $method,
|
||
ActionParameters $params,
|
||
Action $actionAttribute
|
||
): ComponentUpdate {
|
||
$idempotencyKey = $params->getIdempotencyKey();
|
||
$ttl = $actionAttribute->idempotencyTTL;
|
||
|
||
$cachedResult = $this->idempotencyService->get($idempotencyKey);
|
||
|
||
if ($cachedResult !== null) {
|
||
return $cachedResult; // Return cached result for duplicate request
|
||
}
|
||
|
||
$result = $this->executeActionAndBuildUpdate($component, $method, $params);
|
||
|
||
$this->idempotencyService->store($idempotencyKey, $result, $ttl);
|
||
|
||
return $result;
|
||
}
|
||
```
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Strong authentication failure prevention
|
||
|
||
**Recommendations**:
|
||
- ✅ Already implemented - Brute force + replay attack protection
|
||
- Consider: Add account lockout after N failed authorization attempts
|
||
- Consider: Document session timeout configuration
|
||
- Consider: Implement multi-factor authentication (MFA) support for sensitive actions
|
||
|
||
---
|
||
|
||
### A08:2021 – Software and Data Integrity Failures ✅ EXCELLENT
|
||
|
||
**Status**: **BEST IN CLASS** - Integrity protection at multiple layers
|
||
|
||
**Implemented Controls**:
|
||
|
||
1. **Immutable State Architecture** (Framework Principle)
|
||
- Readonly Value Objects enforce immutability
|
||
- State changes only via validated action methods
|
||
- No direct property mutation possible
|
||
- Type system prevents data corruption
|
||
|
||
2. **State Validation** (`DefaultStateValidator`)
|
||
- Schema-based validation on every state change
|
||
- Type checking prevents data type corruption
|
||
- Required field validation prevents incomplete state
|
||
- Unexpected field detection prevents data injection
|
||
|
||
3. **Idempotency Keys** (Data Integrity)
|
||
- Prevents duplicate operations
|
||
- Ensures exactly-once execution semantics
|
||
- Cached results guarantee consistent outcomes
|
||
|
||
4. **CSRF Tokens** (Request Integrity)
|
||
- Prevents unauthorized state changes
|
||
- Per-component-instance scope
|
||
- Session-based validation
|
||
|
||
**Framework Principles Supporting Integrity**:
|
||
```php
|
||
// Readonly Value Objects - Immutability by design
|
||
final readonly class CounterState
|
||
{
|
||
public function __construct(
|
||
public int $count
|
||
) {}
|
||
|
||
// State changes return NEW instance (immutable)
|
||
public function increment(): self
|
||
{
|
||
return new self($this->count + 1);
|
||
}
|
||
}
|
||
|
||
// Type-safe action execution
|
||
#[Action]
|
||
public function increment(): CounterState
|
||
{
|
||
// MUST return CounterState (validated by framework)
|
||
// Cannot return void/null/array/primitive types
|
||
return $this->state->increment();
|
||
}
|
||
```
|
||
|
||
**Risk Assessment**: ✅ **LOW** - Excellent data integrity protection
|
||
|
||
**Recommendations**:
|
||
- ✅ Already implemented - Framework architecture enforces integrity
|
||
- Consider: Add digital signatures for critical state transitions
|
||
- Consider: Implement state change audit logging
|
||
|
||
---
|
||
|
||
### A09:2021 – Security Logging and Monitoring Failures ⚠️ NEEDS IMPROVEMENT
|
||
|
||
**Status**: **NEEDS IMPROVEMENT** - Logging exists but lacks comprehensive security events
|
||
|
||
**Current State**:
|
||
- Framework has OWASP security logging infrastructure
|
||
- LiveComponents layer missing explicit security event logging
|
||
- No documented security monitoring dashboard
|
||
|
||
**Missing Controls**:
|
||
|
||
1. ❌ **Security Event Logging**
|
||
- CSRF validation failures not logged
|
||
- Rate limit violations not logged to security events
|
||
- Authorization failures not logged
|
||
- Suspicious activity not flagged
|
||
|
||
2. ❌ **Audit Trail**
|
||
- State changes not audited
|
||
- Action executions not logged with user context
|
||
- No retention policy documented
|
||
|
||
**Risk Assessment**: ⚠️ **MEDIUM** - Security incidents may go undetected
|
||
|
||
**Recommendations**:
|
||
|
||
**Priority 1 - HIGH**: Implement Security Event Logging Integration
|
||
```php
|
||
use App\Framework\Security\OWASPSecurityLogger;
|
||
use App\Framework\Security\OWASPEventIdentifier;
|
||
|
||
final readonly class LiveComponentHandler
|

public function __construct(
|
||
// ... existing dependencies
|
||
private readonly OWASPSecurityLogger $securityLogger
|
||
) {}
|
||
|
||
private function validateCsrf(ComponentId $componentId, ActionParameters $params): void
|
||
{
|
||
if (! $params->hasCsrfToken()) {
|
||
// LOG: CSRF token missing
|
||
$this->securityLogger->logSecurityEvent(
|
||
new SecurityEventType(OWASPEventIdentifier::INPUT_VALIDATION_FAILURE),
|
||
context: [
|
||
'component_id' => $componentId->toString(),
|
||
'reason' => 'csrf_token_missing',
|
||
'threat_level' => 'high'
|
||
]
|
||
);
|
||
|
||
throw new \InvalidArgumentException('CSRF token required');
|
||
}
|
||
|
||
// ... existing CSRF validation
|

```
|
||
|
||
**Priority 2 - MEDIUM**: Add Action Execution Audit Logging
|
||
```php
|
||
private function executeAction(
|
||
LiveComponentContract $component,
|
||
string $method,
|
||
ActionParameters $params
|
||
): object {

$startTime = microtime(true);
|
||
|
||
try {
|
||
$newState = $component->$method();
|
||
|
||
// LOG: Successful action execution
|
||
$this->auditLogger->logActionExecution([
|
||
'component' => get_class($component),
|
||
'component_id' => $component->id->toString(),
|
||
'action' => $method,
|
||
'user_id' => $this->authorizationChecker->getUserId(),
|
||
'execution_time_ms' => (microtime(true) - $startTime) * 1000,
|
||
'status' => 'success'
|
||
]);
|
||
|
||
return $newState;
|
||
} catch (\Throwable $e) {
|
||
// LOG: Failed action execution
|
||
$this->auditLogger->logActionExecution([
|
||
'component' => get_class($component),
|
||
'action' => $method,
|
||
'status' => 'failed',
|
||
'error' => $e->getMessage()
|
||
]);
|
||
|
||
throw $e;
|
||
}
|
||
}
|
||
```
|
||
|
||
**Priority 3 - LOW**: Document Security Monitoring Dashboard Requirements
|
||
- Real-time CSRF attack detection alerts
|
||
- Rate limit violation trending
|
||
- Authorization failure patterns
|
||
- Suspicious activity detection (e.g., rapid component instantiation)
|
||
|
||
---
|
||
|
||
### A10:2021 – Server-Side Request Forgery (SSRF) ✅ NOT APPLICABLE
|
||
|
||
**Status**: **NOT APPLICABLE** - LiveComponents does not make external requests
|
||
|
||
**Analysis**:
|
||
- LiveComponents system handles client-server state synchronization
|
||
- No URL fetching or external HTTP requests in LiveComponents layer
|
||
- File uploads handled via framework's upload system (separate layer)
|
||
- No user-controlled URLs processed
|
||
|
||
**Risk Assessment**: ✅ **NOT APPLICABLE**
|
||
|
||
**Recommendations**:
|
||
- ✅ No action required
|
||
- If future features add external requests, implement URL validation and allowlist
