CVE-2026-4319 identifies a SQL injection vulnerability in the Simple Food Order System version 1.0 developed by code-projects. The vulnerability resides in the /routers/add-item.php script, specifically in the handling of the 'price' parameter. Due to insufficient input validation or sanitization, an attacker can manipulate this parameter to inject arbitrary SQL commands into the backend database query. This injection flaw allows remote attackers to execute unauthorized SQL queries without requiring authentication or user interaction, increasing the attack surface. The vulnerability can lead to unauthorized data disclosure, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's database. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no active exploitation in the wild has been reported, a public exploit exists, making it easier for attackers to leverage this vulnerability. The lack of patch links suggests that a fix may not yet be officially released, emphasizing the need for immediate mitigation by users of this software. This vulnerability is typical of web applications that fail to use parameterized queries or proper input sanitization, a common security oversight in PHP-based systems.

The impact of CVE-2026-4319 on organizations using the affected Simple Food Order System can be significant. Successful exploitation allows attackers to execute arbitrary SQL commands remotely, potentially leading to unauthorized access to sensitive customer and order data, manipulation or deletion of records, and disruption of service availability. This can result in data breaches, financial losses, reputational damage, and regulatory compliance violations, especially for businesses handling payment or personal information. Since the vulnerability requires no authentication and no user interaction, it can be exploited at scale by automated tools, increasing the risk of widespread compromise. Organizations relying on this system for order processing may experience operational disruptions, impacting customer satisfaction and revenue. The presence of a public exploit further elevates the threat level, as less skilled attackers can attempt exploitation. However, the medium severity rating reflects that the impact is partial rather than complete compromise, and the vulnerability is limited to a specific component and version of the software.

To mitigate CVE-2026-4319, organizations should immediately review and update the input handling code in /routers/add-item.php to ensure the 'price' parameter is properly validated and sanitized. The most effective mitigation is to refactor the database queries to use parameterized queries or prepared statements, which prevent SQL injection by separating code from data. 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 'price' parameter can provide temporary protection. Organizations should also monitor logs for suspicious activity related to this endpoint and restrict access to the application where possible. Regular security testing, including dynamic application security testing (DAST), can help identify similar injection flaws. Finally, organizations should track vendor updates for official patches and apply them promptly once available. Educating developers on secure coding practices and conducting code reviews can prevent recurrence of such vulnerabilities.
