CVE-2026-1118 identifies a SQL Injection vulnerability in the itsourcecode Society Management System version 1.0, located in the /admin/add_activity.php file. The vulnerability stems from insufficient input validation of the 'Title' parameter, which is susceptible to SQL Injection attacks. This allows an unauthenticated remote attacker to manipulate SQL queries executed by the backend database, potentially leading to unauthorized data disclosure, data modification, or even full system compromise depending on the database privileges. The vulnerability does not require user interaction and can be exploited remotely, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the ease of exploitation (low attack complexity, no privileges or user interaction required) but limited scope and impact (low confidentiality, integrity, and availability impact). No official patches or fixes have been published yet, and no known exploits are currently active in the wild, though a public exploit is available. The affected product is a niche society management system, which may limit the overall exposure but still poses a significant risk to organizations relying on this software for community or society management functions.

The primary impact of this vulnerability is unauthorized access to or manipulation of the backend database of the Society Management System. Attackers could extract sensitive information such as user data, membership details, or administrative records. They could also alter or delete data, disrupting the normal operation of the system and potentially causing denial of service or reputational damage. Since the vulnerability is remotely exploitable without authentication, it increases the attack surface significantly. Organizations using this software may face data breaches, loss of data integrity, and operational interruptions. The impact is particularly critical for organizations managing sensitive community or society data, where confidentiality and integrity are paramount. However, the limited market penetration of the product and the medium severity rating somewhat constrain the overall global impact.

To mitigate this vulnerability, organizations should immediately implement input validation and sanitization on the 'Title' parameter in /admin/add_activity.php to prevent SQL Injection. Employ parameterized queries or prepared statements to ensure that user input cannot alter SQL command structure. Restrict access to the administrative interface using network-level controls such as VPNs or IP whitelisting to reduce exposure. Monitor logs for suspicious SQL query patterns indicative of injection attempts. Since no official patch is available, consider applying virtual patching via Web Application Firewalls (WAF) configured to detect and block SQL Injection payloads targeting this endpoint. Additionally, conduct a comprehensive security review of the application to identify and remediate similar injection flaws. Plan for an upgrade or replacement of the software if vendor support is lacking.
