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, allowing attackers to inject arbitrary SQL commands. This vulnerability can be exploited remotely without authentication or user interaction, making it accessible to unauthenticated attackers over the network. The injection could enable attackers to read, modify, or delete data within the backend database, potentially compromising confidentiality and integrity of stored information such as order details, user data, or system configurations. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The vulnerability is limited to version 1.0 of this specific software, which is a niche product used primarily for food ordering management. No official patches or updates have been linked yet, suggesting that users must implement manual mitigations or monitor for vendor updates. This vulnerability highlights the importance of secure coding practices, especially input validation and use of parameterized queries to prevent SQL injection attacks.

The impact of CVE-2026-4533 on organizations using the affected Simple Food Ordering System can be significant. Successful exploitation allows attackers to execute arbitrary SQL commands remotely, potentially leading to unauthorized disclosure of sensitive customer and order information, modification or deletion of critical data, and disruption of ordering services. This can result in data breaches, loss of customer trust, financial losses, and regulatory penalties, especially if personal or payment data is involved. The medium severity rating reflects partial impact on confidentiality, integrity, and availability, but the lack of authentication requirement and remote exploitability increase the risk. However, the limited market penetration of this specific software reduces the overall global impact. Organizations relying on this system, particularly small to medium-sized food service providers, may face operational disruptions and reputational damage if exploited. The presence of public exploit code raises the risk of opportunistic attacks, especially from automated scanning and exploitation tools targeting vulnerable web applications.

To mitigate CVE-2026-4533, organizations should immediately implement the following specific actions: 1) Apply input validation and sanitization on the 'Status' parameter in all-tickets.php to ensure only expected values are accepted. 2) Refactor database queries to use parameterized statements or prepared queries to prevent SQL injection. 3) Restrict database user permissions to the minimum necessary, limiting the impact of any injection. 4) Monitor web application logs for suspicious query patterns or repeated failed attempts targeting the 'Status' parameter. 5) If vendor patches become available, prioritize timely application. 6) Consider deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting this parameter. 7) Conduct security code reviews and penetration testing on the application to identify and remediate similar injection points. 8) Educate developers on secure coding practices to prevent future injection vulnerabilities. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable parameter and the context of this application.
