CVE-2026-1176 is a SQL Injection vulnerability identified in the itsourcecode School Management System version 1.0. The vulnerability exists in an unspecified function within the /subject/index.php file, where the ID parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This flaw can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. Successful exploitation can lead to unauthorized data access, data modification, or deletion, compromising the confidentiality, integrity, and availability of the school management system’s database. The CVSS 4.0 score of 6.9 reflects a medium severity level, considering the attack vector is network-based with low attack complexity and no privileges or user interaction required. However, the impact on data confidentiality, integrity, and availability is limited to low levels individually but combined can be significant. No official patches or fixes have been published yet, and although no known exploits are currently active in the wild, a public exploit code has been released, increasing the likelihood of exploitation. The vulnerability is particularly concerning for educational institutions relying on this software for managing sensitive student and staff information. Without proper mitigation, attackers could extract sensitive data such as personal information, grades, or attendance records, or manipulate records to disrupt school operations.

For European organizations, particularly educational institutions using the itsourcecode School Management System, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive student and staff data. Exploitation could lead to unauthorized disclosure of personal data, violating GDPR and other data protection regulations, potentially resulting in legal and financial penalties. Data manipulation could disrupt academic records, affecting students’ academic progress and institutional reputation. Availability impacts could arise if attackers delete or corrupt data, causing operational downtime. The public availability of exploit code increases the risk of opportunistic attacks, especially against under-resourced schools lacking robust cybersecurity defenses. The medium severity rating suggests moderate but tangible risks, emphasizing the need for timely remediation to prevent data breaches and operational disruptions.

Organizations should immediately implement input validation and sanitization on all user-supplied parameters, especially the ID parameter in /subject/index.php. Employing parameterized queries or prepared statements is critical to prevent SQL injection. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. Conduct thorough code reviews and security testing of the application to identify and remediate similar vulnerabilities. Monitor network traffic and application logs for suspicious SQL queries or unusual access patterns. If possible, isolate the school management system behind a web application firewall (WAF) configured to detect and block SQL injection attempts. Educate IT staff and administrators about the vulnerability and the importance of applying security best practices. Since no official patch is available, consider temporary mitigations such as disabling the vulnerable functionality or restricting access to trusted IP addresses until a vendor patch is released. Regularly back up critical data to enable recovery in case of data corruption or deletion.
