CVE-2025-14210 identifies a SQL injection vulnerability in version 1.0 of the projectworlds Advanced Library Management System, specifically within the /delete_member.php script. The vulnerability arises from improper sanitization of the user_id parameter, which is directly incorporated into SQL queries without adequate validation or use of parameterized statements. This flaw allows remote attackers to inject malicious SQL code, potentially enabling unauthorized access to the underlying database, data extraction, modification, or deletion. The attack vector is network-based, requiring no authentication or user interaction, which significantly lowers the barrier for exploitation. The vulnerability has been publicly disclosed, although no active exploits have been reported in the wild to date. The CVSS 4.0 base score of 6.9 (medium severity) reflects the vulnerability's potential to impact confidentiality, integrity, and availability to a limited extent, with low complexity of attack and no privileges required. The affected product is primarily used in library management environments, which often contain sensitive patron and organizational data. The lack of available patches or official remediation guidance increases the urgency for organizations to implement their own mitigations. Given the nature of the vulnerability, attackers could leverage this flaw to manipulate membership records, extract sensitive user data, or disrupt library services.

For European organizations, particularly academic institutions, public libraries, and cultural heritage centers utilizing the projectworlds Advanced Library Management System, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive user and organizational data. Exploitation could lead to unauthorized disclosure of personal information, membership details, or operational data, potentially violating GDPR and other data protection regulations. Additionally, attackers could alter or delete membership records, disrupting library operations and availability of services. The remote and unauthenticated nature of the attack increases the likelihood of exploitation, especially in environments with internet-facing management interfaces. This could result in reputational damage, legal liabilities, and operational downtime. The absence of known exploits in the wild currently limits immediate impact but the public disclosure raises the risk of future attacks. Organizations may also face challenges in incident response due to the lack of official patches or detailed remediation instructions.

To mitigate this vulnerability, European organizations should immediately audit and restrict access to the /delete_member.php endpoint, ideally limiting it to trusted internal networks or VPNs. Implementing strict input validation and sanitization on the user_id parameter is critical; this includes enforcing type checks (e.g., numeric only) and length restrictions. Refactoring the code to use parameterized queries or prepared statements will prevent SQL injection attacks effectively. Organizations should conduct thorough code reviews and penetration testing focused on SQL injection vectors within the application. Monitoring database logs and web server access logs for suspicious or anomalous queries targeting the vulnerable endpoint can help detect exploitation attempts early. If possible, isolate the affected system from external networks until remediation is complete. Additionally, organizations should engage with the vendor or community to obtain or develop patches and apply them promptly once available. Regular backups of membership and database data should be maintained to enable recovery in case of data corruption or deletion. Finally, raising awareness among IT and security teams about this vulnerability will enhance preparedness and response capabilities.
