CVE-2025-13254 is a SQL injection vulnerability identified in projectworlds Advanced Library Management System version 1.0. The vulnerability resides in the /add_member.php script, where the roll_number parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without requiring authentication or user interaction, enabling attackers to manipulate backend database queries. The vulnerability could lead to unauthorized data disclosure, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's data. The CVSS 4.0 base score is 5.3 (medium), reflecting the vulnerability's moderate impact and ease of exploitation. Although no active exploits have been reported in the wild, publicly available exploit code increases the likelihood of future attacks. The affected product is a specialized library management system, which may be deployed in educational institutions, public libraries, or similar organizations. The lack of vendor patches or official remediation guidance necessitates immediate defensive measures by users. The vulnerability highlights the critical need for secure coding practices, particularly input validation and the use of parameterized queries to prevent SQL injection attacks.

For European organizations, especially those in the education and public sector using projectworlds Advanced Library Management System 1.0, this vulnerability poses a significant risk of unauthorized access to sensitive member data, including personally identifiable information. Exploitation could lead to data breaches, loss of data integrity through unauthorized modifications, or denial of service if database operations are disrupted. Such incidents can damage organizational reputation, incur regulatory penalties under GDPR due to data exposure, and disrupt library services. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers can exploit the vulnerability without insider access or user interaction. While the product's niche market limits widespread impact, targeted attacks on institutions relying on this system could have outsized consequences. Additionally, the availability of public exploit code lowers the barrier for attackers, increasing the urgency for mitigation in affected environments.

Organizations should immediately audit their use of projectworlds Advanced Library Management System version 1.0 and isolate affected instances. Since no official patches are currently available, developers or administrators should implement input validation and sanitization for the roll_number parameter, ensuring only expected formats are accepted. Refactoring the /add_member.php code to use parameterized queries or prepared statements is critical to prevent SQL injection. Network-level protections such as web application firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting the roll_number parameter. Continuous monitoring of database logs for anomalous queries and unusual access patterns is recommended. Organizations should also consider restricting remote access to the management interface to trusted IP addresses and enforce strict access controls. Finally, planning for an upgrade or replacement of the vulnerable system with a more secure alternative should be prioritized to reduce long-term risk.
