CVE-2026-5019 identifies a SQL injection vulnerability in the Simple Food Order System version 1.0 developed by code-projects. The flaw exists in the all-orders.php file within the Parameter Handler component, where the 'Status' argument is not properly sanitized or validated before being used in SQL queries. This improper handling allows an unauthenticated remote attacker to inject arbitrary SQL commands by manipulating the 'Status' parameter. The vulnerability does not require user interaction or authentication, making it easier to exploit over the network. Successful exploitation could lead to unauthorized reading, modification, or deletion of database records, potentially exposing sensitive order information or disrupting order processing. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, no privileges or user interaction required, and limited but non-negligible impact on confidentiality, integrity, and availability. Although no public exploit code is currently known to be actively used in the wild, the public disclosure increases the risk of future exploitation. The affected software is a specialized food ordering system, which may be deployed by small to medium-sized restaurants or food service providers. The lack of available patches necessitates immediate mitigation through secure coding practices such as parameterized queries and input validation.

The primary impact of this vulnerability is unauthorized access and manipulation of the backend database of the Simple Food Order System. Attackers could extract sensitive customer order data, modify order statuses, or delete records, leading to data breaches, financial loss, and operational disruption. For organizations relying on this system, this could result in compromised customer trust, regulatory penalties for data exposure, and potential downtime affecting business continuity. Since the vulnerability can be exploited remotely without authentication, it increases the attack surface significantly. While the scope is limited to users of this specific software, any deployment in production environments handling real customer data is at risk. The integrity of order processing could be undermined, leading to incorrect orders or denial of service. The medium severity rating suggests moderate but actionable risk, especially for organizations lacking compensating controls or monitoring.

1. Immediately review and sanitize all inputs, especially the 'Status' parameter in all-orders.php, using strict whitelist validation. 2. Refactor the code to use parameterized queries or prepared statements to prevent direct SQL injection. 3. If available, apply official patches or updates from the vendor; if not, consider upgrading to a newer, secure version or alternative software. 4. Implement Web Application Firewalls (WAF) with SQL injection detection rules to block malicious payloads targeting this parameter. 5. Conduct thorough code audits and penetration testing focusing on input handling and database interactions. 6. Monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. 7. Restrict database user permissions to the minimum necessary to limit potential damage from injection attacks. 8. Educate developers and administrators about secure coding practices and the risks of SQL injection. 9. Consider isolating the affected system within the network and applying network segmentation to reduce exposure. 10. Backup databases regularly to enable recovery in case of data tampering or loss.
