CVE-2026-2116 identifies a SQL Injection vulnerability in the itsourcecode Society Management System version 1.0. The vulnerability exists in the /admin/edit_expenses.php file, where the expenses_id parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it particularly dangerous. The attacker can manipulate SQL queries executed by the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. The CVSS 4.0 base score of 6.9 reflects a medium severity, considering the vulnerability's ease of exploitation (network attack vector, low attack complexity) and the lack of required privileges or user interaction. The impact on confidentiality, integrity, and availability is limited but present, as the vulnerability allows partial compromise of the database content. No patches or fixes have been officially released yet, and no known exploits are currently observed in the wild. However, the public disclosure of the vulnerability increases the risk of exploitation by threat actors. The vulnerability affects only version 1.0 of the software, which is used for managing societies or community organizations, potentially exposing sensitive financial or membership data. The lack of secure coding practices in input handling is the root cause, emphasizing the need for parameterized queries and input validation.

For European organizations using the itsourcecode Society Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive financial and administrative data managed within the system. Exploitation could lead to data breaches involving personal or financial information of society members, undermining privacy and trust. Integrity of financial records could be compromised, affecting accounting accuracy and potentially leading to fraud or financial loss. Availability might be impacted if attackers manipulate or delete critical data, disrupting society management operations. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable systems over the internet, increasing exposure. Organizations involved in community management, housing societies, or local administrative bodies using this software are particularly at risk. The medium severity indicates a significant but not catastrophic impact, yet the potential for lateral movement or further exploitation exists if attackers gain foothold. Compliance with European data protection regulations (e.g., GDPR) could be jeopardized if personal data is exposed or mishandled due to this vulnerability.

To mitigate CVE-2026-2116, organizations should immediately restrict access to the /admin/edit_expenses.php interface by implementing network-level controls such as IP whitelisting or VPN access to limit exposure. Apply strict input validation and sanitization on the expenses_id parameter, ensuring only expected numeric or alphanumeric values are accepted. Refactor the backend code to use parameterized SQL queries or prepared statements to eliminate injection vectors. Monitor logs for suspicious SQL query patterns or unexpected database errors indicative of attempted exploitation. If possible, isolate the affected system within a segmented network zone to reduce lateral movement risk. Engage with the vendor or community to obtain patches or updates addressing this vulnerability and apply them promptly once available. Conduct regular security assessments and penetration tests focusing on injection flaws in all web-facing applications. Educate administrators on recognizing signs of compromise and maintaining strong authentication and authorization controls for administrative interfaces. Implement web application firewalls (WAF) with rules targeting SQL injection attempts as an additional protective layer.
