CVE-2026-5018 identifies a SQL injection vulnerability in the Simple Food Order System version 1.0 developed by code-projects. The vulnerability resides in the register-router.php file's Parameter Handler component, specifically involving the 'Name' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code into backend database queries. This injection flaw arises from insufficient input validation and lack of parameterized queries, allowing attackers to alter SQL statements executed by the application. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 base score is 6.9, reflecting medium severity with network attack vector, low attack complexity, and no privileges or user interaction needed. The impact includes potential unauthorized data disclosure, data modification, or deletion, which can compromise the confidentiality, integrity, and availability of the system's data. Although no exploits are currently reported in the wild, the public availability of exploit code increases the likelihood of attacks. The affected product is a niche food ordering system, which may limit the overall exposure but still poses significant risks to organizations relying on this software for order management. No official patches or updates have been linked, so mitigation relies on secure coding corrections and input sanitization.

The SQL injection vulnerability in the Simple Food Order System can have serious consequences for affected organizations. Attackers exploiting this flaw can gain unauthorized access to sensitive customer and order data stored in the backend database, leading to data breaches and privacy violations. They may also alter or delete data, disrupting order processing and causing operational downtime. This can damage the reputation of food service providers using the system and result in financial losses. Since the vulnerability allows remote exploitation without authentication, attackers can launch automated attacks at scale, increasing the risk of widespread compromise. The lack of user interaction requirement further lowers the barrier for exploitation. Although the product is niche, organizations using it in countries with large food delivery markets or where this software is popular face elevated risks. The potential impact extends beyond data loss to include regulatory non-compliance and customer trust erosion.

To mitigate CVE-2026-5018, organizations should immediately review and update the affected code, particularly the register-router.php file's handling of the 'Name' parameter. Developers must implement strict input validation and sanitization to reject malicious input. The use of parameterized queries or prepared statements is critical to prevent SQL injection by separating code from data. If possible, upgrade to a patched version once available or apply custom patches to fix the vulnerability. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting this parameter. Conduct thorough security testing, including automated scanning and manual code review, to identify and remediate similar injection flaws. Limit database user privileges to the minimum necessary to reduce potential damage. Monitor logs for suspicious activity related to the vulnerable endpoint. Finally, educate development teams on secure coding practices to prevent future injection vulnerabilities.
