CVE-2025-8437 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Kitchen Treasure application, specifically within the /userregistration.php file. The vulnerability arises from improper sanitization or validation of the 'email' parameter, which allows an attacker to inject malicious SQL code remotely without any authentication or user interaction. This injection can manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even full compromise of the database. The CVSS 4.0 score of 6.9 categorizes it as a medium severity vulnerability, reflecting the ease of remote exploitation (no privileges or user interaction required) but with limited impact on confidentiality, integrity, and availability (all rated low). Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts. The absence of available patches or mitigations from the vendor further elevates the urgency for affected organizations to implement compensating controls. Given the nature of SQL Injection, attackers could extract sensitive user data, alter registration records, or disrupt service functionality, impacting both the integrity and availability of the application.

For European organizations using Kitchen Treasure 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of user data, especially personal information collected during user registration. Exploitation could lead to unauthorized access to sensitive customer data, regulatory non-compliance (e.g., GDPR violations), and reputational damage. Additionally, attackers could manipulate or delete registration data, disrupting business operations and customer trust. Since the vulnerability can be exploited remotely without authentication, attackers from anywhere could target European deployments, increasing the threat landscape. The lack of vendor patches means organizations must rely on internal mitigations, which may not fully eliminate risk. This is particularly critical for sectors handling sensitive personal or financial data, such as hospitality, retail, or food service businesses using Kitchen Treasure for customer engagement or loyalty programs.

Given the absence of official patches, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'email' parameter in /userregistration.php. 2) Conduct thorough input validation and sanitization on all user-supplied data, especially the email field, using parameterized queries or prepared statements if source code access is available. 3) Restrict database user permissions to the minimum necessary to limit the impact of any injection attack. 4) Monitor application logs and database queries for unusual activity indicative of injection attempts. 5) If feasible, isolate the affected application environment from critical internal networks to contain potential breaches. 6) Engage with the vendor or community to track any forthcoming patches or updates and plan for timely application. 7) Consider temporary disabling or restricting access to the vulnerable registration functionality until a permanent fix is available.
