CVE-2026-1119 identifies a SQL injection vulnerability in the itsourcecode Society Management System version 1.0. The vulnerability exists in the /admin/delete_activity.php script, where the activity_id parameter is not properly sanitized or validated before being used in SQL queries. This allows an unauthenticated remote attacker to inject malicious SQL code by manipulating the activity_id argument. The injection flaw can be exploited to read, modify, or delete database records, potentially leading to unauthorized data disclosure, data corruption, or denial of service conditions. The vulnerability does not require any privileges or user interaction, making it easier to exploit remotely. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no confirmed active exploitation has been reported, a public exploit is available, increasing the likelihood of attacks. The lack of official patches or updates from the vendor at this time further exacerbates the risk. This vulnerability highlights the importance of input validation and parameterized queries in web applications managing sensitive community data.

The impact of CVE-2026-1119 is significant for organizations using the itsourcecode Society Management System 1.0. Successful exploitation can lead to unauthorized access to sensitive community management data, including activity logs and user information. Attackers may manipulate or delete records, undermining data integrity and disrupting normal operations. Confidentiality breaches could expose personally identifiable information or internal administrative data. Availability may also be affected if attackers cause database errors or crashes. Given the remote, unauthenticated nature of the exploit, attackers can operate stealthily and at scale. This poses risks to municipalities, housing societies, or community organizations relying on this software for governance and communication. The presence of a public exploit increases the urgency for mitigation to prevent data breaches, reputational damage, and potential regulatory consequences related to data protection laws.

To mitigate CVE-2026-1119, organizations should immediately implement the following measures: 1) Apply any available patches or updates from the vendor once released. 2) If patches are unavailable, implement web application firewall (WAF) rules to detect and block malicious SQL injection payloads targeting the activity_id parameter. 3) Conduct a thorough code review and refactor the vulnerable /admin/delete_activity.php script to use parameterized queries or prepared statements, ensuring proper input validation and sanitization. 4) Restrict access to the /admin directory by IP whitelisting or VPN to limit exposure. 5) Monitor database logs and application logs for suspicious queries or anomalies related to activity_id usage. 6) Educate administrators on the risk and signs of exploitation attempts. 7) Consider deploying runtime application self-protection (RASP) tools to detect and prevent injection attacks in real time. These steps go beyond generic advice by focusing on immediate protective controls and secure coding practices tailored to this specific vulnerability.
