CVE-2025-14210 identifies a SQL injection vulnerability in projectworlds Advanced Library Management System version 1.0, located in the /delete_member.php script. The vulnerability arises from improper sanitization of the user_id parameter, allowing attackers to inject malicious SQL code remotely without authentication or user interaction. This injection can manipulate backend database queries, potentially enabling attackers to read, modify, or delete sensitive data within the library management system's database. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of remote exploitation and the potential impact on confidentiality, integrity, and availability, albeit with limited scope and no privilege or user interaction requirements. Although no exploits have been observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation by threat actors. The Advanced Library Management System is typically deployed in academic and public library environments, where sensitive patron and institutional data is stored. The lack of available patches necessitates immediate code review and remediation by implementing secure coding practices such as prepared statements and input validation to prevent SQL injection attacks.

For European organizations, particularly educational institutions, public libraries, and research centers using projectworlds Advanced Library Management System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to personal patron data, membership records, and potentially administrative credentials, compromising confidentiality. Data integrity may be affected if attackers modify or delete records, disrupting library operations and trust. Availability could also be impacted if attackers execute destructive queries or cause database errors, leading to service outages. The medium severity score indicates a moderate but tangible risk, especially given the lack of authentication requirements and remote exploitability. The exposure of sensitive data could have regulatory implications under GDPR, leading to legal and reputational damage. Organizations relying on this system must assess their exposure and prioritize remediation to avoid data breaches and operational disruptions.

Immediate mitigation should focus on code-level remediation by sanitizing the user_id parameter in /delete_member.php. Developers must implement parameterized queries or prepared statements to prevent SQL injection. Input validation should enforce strict type and format checks on user_id values. In the absence of an official patch, organizations can apply web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this endpoint. Regular database activity monitoring and anomaly detection can help identify exploitation attempts early. Additionally, restricting access to the /delete_member.php endpoint through network segmentation or authentication mechanisms can reduce exposure. Organizations should also conduct thorough security audits of the entire application to identify and remediate similar vulnerabilities. Finally, maintaining up-to-date backups ensures recovery in case of data corruption or loss.
