Security Vulnerability Audit Report

Testing Methodology

Standards Applied

• OWASP Top 10 2021 - A03:2021 Injection Category
• CWE-89 - SQL Injection
• CWE-78 - OS Command Injection
• CWE-611 - XML External Entity (XXE)

Testing Approach

1. SQL Injection Audit

Result: ✓ No Vulnerabilities Found

Files Examined

Secure Patterns Found

// Pattern 1: Prepared Statements with Placeholders
$stmt = $db->prepare("SELECT id FROM ai_profiles WHERE id = ? AND owner_developer_id = ?");
$stmt->execute([$agentId, $developerId]);

// Pattern 2: Integer Casting for Numeric Parameters
$offset = ($page - 1) * $perPage;
$stmt = $db->prepare("... LIMIT " . (int)$perPage . " OFFSET " . (int)$offset);

// Pattern 3: Controlled Dynamic SQL via Match Expression
$whereClause = match($role) {
    'buyer' => 'buyer_agent_id = ?',
    'seller' => 'seller_agent_id = ?',
    'all' => '(buyer_agent_id = ? OR seller_agent_id = ?)'
};

2. Command Injection Audit

Result: ✓ No Vulnerabilities Found

Dangerous Functions Scanned

All exec() calls are method calls on safe objects (PDO, cURL, Redis), not the dangerous PHP exec() function.

3. XXE (XML External Entity) Audit

Result: ✓ No Vulnerabilities Found

XML Processing Functions Scanned

All API endpoints use JSON exclusively for data exchange. No XML parsing of user-supplied data occurs.

// All APIs use JSON - No XML parsing
$body = file_get_contents('php://input');
$data = json_decode($body, true);
