CVE-2026-4533 identifies a SQL injection vulnerability in the Simple Food Ordering System version 1.0 developed by code-projects. The flaw exists in the all-tickets.php file, where the 'Status' parameter is improperly sanitized, enabling attackers to manipulate SQL queries executed by the backend database. This vulnerability can be exploited remotely without requiring authentication or user interaction, increasing its risk profile. The injection allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized data disclosure, data modification, or deletion. The CVSS 4.0 base score is 5.3 (medium), reflecting the ease of exploitation (network attack vector, low attack complexity) but limited impact scope and privileges required (low privileges). No official patches or fixes have been published yet, and while exploit code is publicly available, there are no confirmed active exploits in the wild. The vulnerability primarily threatens organizations using this specific food ordering system, which may be deployed in small to medium-sized restaurants or food service providers. The lack of authentication requirements and remote exploitability make it critical to address promptly. The vulnerability highlights the importance of secure coding practices, especially input validation and use of parameterized queries to prevent SQL injection attacks.

The primary impact of CVE-2026-4533 is unauthorized access to or manipulation of the backend database of the Simple Food Ordering System. Attackers exploiting this vulnerability could retrieve sensitive customer data, order details, or internal system information, leading to confidentiality breaches. Data integrity could also be compromised if attackers modify or delete records, potentially disrupting business operations or causing financial losses. Availability impact is limited but possible if attackers execute destructive SQL commands. Given the system's role in processing food orders, exploitation could result in operational disruptions for affected businesses. Although the product's market penetration appears limited, organizations relying on this software without mitigation are at risk of data breaches and reputational damage. The public availability of exploit code increases the likelihood of opportunistic attacks, especially against poorly secured deployments. The medium severity rating indicates a moderate but tangible risk that requires timely remediation to prevent exploitation.

To mitigate CVE-2026-4533, organizations should immediately review and update the all-tickets.php file to implement strict input validation and sanitize the 'Status' parameter. The best practice is to replace dynamic SQL queries with parameterized prepared statements or stored procedures to eliminate SQL injection vectors. If source code modification is not immediately feasible, deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting the 'Status' parameter can provide temporary protection. Restricting network access to the vulnerable endpoint to trusted IP addresses and monitoring logs for suspicious query patterns are additional defensive measures. Organizations should also conduct a thorough security audit of the entire application to identify and remediate similar injection flaws. Regular backups of the database are recommended to enable recovery in case of data tampering. Finally, maintain awareness of vendor updates or patches and apply them promptly once available.
