CVE-2026-2116 identifies a SQL injection vulnerability in the itsourcecode Society Management System version 1.0, located in the /admin/edit_expenses.php file. The vulnerability is triggered by manipulation of the expenses_id parameter, which is not properly sanitized or validated before being used in SQL queries. This flaw allows an attacker to inject arbitrary SQL commands remotely without requiring authentication or user interaction, potentially leading to unauthorized access to sensitive data, data corruption, or deletion. The vulnerability has been publicly disclosed, increasing the likelihood of exploitation attempts. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the ease of remote exploitation and the potential impact on confidentiality, integrity, and availability, but limited by the scope and lack of known active exploits. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous for exposed systems. Organizations using this software should conduct thorough code reviews, implement input validation, and monitor database queries to detect and prevent exploitation.

The SQL injection vulnerability can have significant impacts on affected organizations, including unauthorized disclosure of sensitive financial or personal data managed by the Society Management System. Attackers could manipulate or delete expense records, leading to financial discrepancies and loss of data integrity. The availability of the system could also be affected if attackers execute destructive queries or cause database corruption. Given the administrative nature of the affected functionality, the impact on organizational operations could be substantial, especially for community or society management entities relying on this software for critical administrative tasks. The remote and unauthenticated exploitation vector increases the risk of widespread attacks, potentially affecting multiple organizations globally. Data breaches resulting from this vulnerability could lead to regulatory penalties, reputational damage, and operational disruptions.

To mitigate this vulnerability, organizations should immediately implement strict input validation and sanitization for the expenses_id parameter, ensuring that only expected numeric or predefined values are accepted. Employing parameterized queries or prepared statements in the database access layer will effectively prevent SQL injection attacks. Until an official patch is released, consider deploying web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the /admin/edit_expenses.php endpoint. Restricting access to the administrative interface by IP whitelisting or VPN-only access can reduce exposure. Regularly monitor database logs and application logs for suspicious query patterns indicative of injection attempts. Conduct security audits and code reviews to identify and remediate similar vulnerabilities elsewhere in the application. Finally, maintain an incident response plan to quickly address any exploitation attempts.
