CVE-2026-1594 is a SQL Injection vulnerability identified in the itsourcecode Society Management System version 1.0, specifically within the /admin/add_expenses.php script. The vulnerability is triggered by the manipulation of the 'detail' parameter, which is inadequately sanitized before being incorporated into SQL queries. This flaw allows remote attackers to inject arbitrary SQL commands without requiring any authentication or user interaction, enabling them to potentially read, modify, or delete sensitive data stored in the backend database. The vulnerability was publicly disclosed on January 29, 2026, and although no known exploits have been reported in the wild, the public availability of the exploit code increases the risk of exploitation. The CVSS 4.0 base score of 6.9 (medium severity) reflects the vulnerability’s characteristics: it is remotely exploitable (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability does not affect system confidentiality or integrity completely but can lead to significant unauthorized data access or manipulation. The lack of patches or official fixes at the time of disclosure further elevates the risk. This vulnerability is particularly concerning for organizations managing community or society data using this software, as attackers could leverage the flaw to compromise financial or membership records. The vulnerability highlights the critical need for secure coding practices, especially input validation and the use of parameterized queries to prevent SQL injection attacks.

For European organizations using the itsourcecode Society Management System 1.0, this SQL Injection vulnerability poses a significant risk to the confidentiality, integrity, and availability of sensitive data related to society management, such as financial records and member information. Exploitation could lead to unauthorized data disclosure, data tampering, or deletion, potentially causing financial loss, reputational damage, and regulatory non-compliance, especially under GDPR requirements. The remote and unauthenticated nature of the exploit increases the attack surface, allowing attackers to compromise systems without insider access. Given the software’s niche use in managing societies or community groups, the impact might be concentrated but severe for affected organizations. Additionally, the lack of official patches means organizations must rely on immediate mitigations to reduce risk. The vulnerability could also be leveraged as a foothold for further attacks within a network, increasing overall organizational risk.

To mitigate CVE-2026-1594, organizations should immediately implement strict input validation and sanitization on the 'detail' parameter within /admin/add_expenses.php. Employing parameterized queries or prepared statements is critical to prevent SQL injection. If source code modification is possible, refactor the vulnerable code to use secure database access methods. Restrict access to the /admin/add_expenses.php endpoint through network segmentation, firewall rules, or VPN requirements to limit exposure. Monitor logs for suspicious SQL query patterns or unusual activity related to this endpoint. In the absence of an official patch, consider deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection attempts targeting this parameter. Conduct thorough security assessments of the entire application to identify and remediate similar injection flaws. Finally, maintain an incident response plan to quickly address any exploitation attempts.
