Attack Chain

1. An attacker identifies an internet-facing instance of code-projects Online Food Order System 1.0.
2. The attacker crafts a specially designed HTTP request, potentially a POST request, targeting the /edit_food_items.php endpoint.
3. Within the crafted request, the attacker injects malicious SQL statements into the 'update' argument, bypassing any insufficient input validation.
4. The vulnerable application processes this request, and due to the lack of proper sanitization, the embedded SQL payload is passed directly to the backend database.
5. The backend database executes the attacker's malicious SQL query, leading to unauthorized data access or manipulation.
6. Through the executed query, the attacker can extract sensitive information (e.g., user credentials, financial data) or alter critical application data.

Impact

Successful exploitation of CVE-2026-15135 can lead to unauthorized information disclosure, allowing attackers to exfiltrate sensitive data from the underlying database, such as customer records, administrator credentials, or financial transaction details. Furthermore, the vulnerability permits data manipulation, enabling attackers to alter, delete, or insert arbitrary data, which could lead to service disruption, financial fraud, or defacement. Given that a public exploit is available, organizations using the affected system face an elevated and immediate risk of compromise, potentially affecting business operations and customer trust.

Recommendation

• Immediately apply patches or vendor-provided mitigations for CVE-2026-15135 in code-projects Online Food Order System 1.0 as soon as they become available.
• Implement and configure a Web Application Firewall (WAF) to detect and block SQL injection attempts, specifically targeting the /edit_food_items.php endpoint and the 'update' argument.
• Deploy the Sigma rule provided in this brief to your SIEM/detection platform to alert on suspicious requests targeting the vulnerable endpoint.
• Review web server access logs for code-projects Online Food Order System for requests to /edit_food_items.php containing suspicious parameters.
