6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Endpoint: /food/routers/cancel-order.php
• Input Parameters: The specific input parameters vulnerable to SQL injection should be identified through code review or dynamic analysis.

Exploitation Example:

-- Example of a malicious SQL injection payload
SELECT * FROM orders WHERE order_id = '1' OR '1'='1';

Mitigation Code Example:

// Example of using prepared statements in PHP
$stmt = $pdo->prepare("SELECT * FROM orders WHERE order_id = :order_id");
$stmt->bindParam(':order_id', $order_id);
$stmt->execute();

Detection Methods:

• Static Analysis: Use static analysis tools to identify SQL injection vulnerabilities in the codebase.
• Dynamic Analysis: Perform dynamic analysis using tools like Burp Suite to test for SQL injection vulnerabilities.

Incident Response:

• Monitoring: Implement monitoring to detect unusual database activities.
• Logging: Ensure comprehensive logging of database queries to facilitate incident response.

Conclusion: CVE-2026-26713 represents a critical vulnerability that requires immediate attention. Organizations should prioritize patching and implementing robust security measures to mitigate the risk.
