CVE-2026-0582 identifies a SQL injection vulnerability in the itsourcecode Society Management System version 1.0, located in the /admin/edit_activity_query.php file. The vulnerability stems from insufficient input validation of the 'Title' parameter, which is used in SQL queries without proper sanitization or parameterization. An attacker can remotely manipulate this parameter to inject arbitrary SQL commands, potentially accessing or modifying the backend database. The vulnerability does not require user interaction and can be exploited without authentication, increasing its risk profile. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges required, but with limited impact on confidentiality, integrity, and availability (low impact on each). No official patches are currently available, and no known exploits have been observed in the wild, though a public exploit exists, which could facilitate attacks. The vulnerability primarily threatens the confidentiality and integrity of data managed by the Society Management System, such as member information and activity records. The lack of secure coding practices in handling SQL queries highlights the need for immediate remediation. Organizations relying on this software should audit their systems, implement input validation, and consider restricting access to the affected administrative interface to mitigate risk.

For European organizations, exploitation of CVE-2026-0582 could lead to unauthorized disclosure of sensitive community or society member data, manipulation or deletion of records, and potential disruption of society management operations. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and operational downtime. The vulnerability's remote exploitability without authentication increases the attack surface, especially for organizations exposing the administrative interface to the internet. Given that society management systems often handle personal data and event information, attackers could leverage this vulnerability to conduct further attacks or data exfiltration. The medium severity rating suggests that while the impact is significant, it may be contained if proper network segmentation and access controls are in place. However, organizations lacking these controls or using version 1.0 of the software without mitigation are at considerable risk.

1. Immediately implement input validation and sanitization on the 'Title' parameter to prevent SQL injection. 2. Refactor the affected code to use parameterized queries or prepared statements instead of dynamic SQL concatenation. 3. Restrict access to the /admin/edit_activity_query.php endpoint by IP whitelisting or VPN access to limit exposure. 4. Conduct a thorough code review of the entire application to identify and remediate similar injection flaws. 5. Monitor logs for suspicious SQL query patterns or unexpected database errors that may indicate exploitation attempts. 6. If possible, upgrade to a patched version once available or apply vendor-provided fixes promptly. 7. Employ Web Application Firewalls (WAF) with rules to detect and block SQL injection payloads targeting this parameter. 8. Educate administrators on the risks and ensure strong authentication and session management to reduce risk of unauthorized access. 9. Regularly backup databases to enable recovery in case of data tampering. 10. Consider network segmentation to isolate the management system from public-facing services.
