CVE-2025-11475 identifies a SQL injection vulnerability in projectworlds Advanced Library Management System version 1.0. The vulnerability resides in the /view_member.php script, where the user_id parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection can be performed remotely without authentication or user interaction, enabling attackers to manipulate backend database queries. Potential consequences include unauthorized retrieval, modification, or deletion of sensitive library member data, as well as possible compromise of the entire database. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, and no privileges or user interaction required, but with limited confidentiality, integrity, and availability impact. No patches or fixes have been publicly released yet, and no known exploits are reported in the wild, but public disclosure increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which is used primarily in library management contexts to handle member information and related operations. Attackers exploiting this flaw could gain unauthorized access to personal data, disrupt library services, or pivot to further attacks within the affected network.

For European organizations, particularly academic institutions, public libraries, and cultural heritage centers relying on projectworlds Advanced Library Management System 1.0, this vulnerability poses a significant risk to member data confidentiality and system integrity. Exploitation could lead to unauthorized disclosure of personally identifiable information (PII), including membership details and borrowing histories, potentially violating GDPR requirements and resulting in regulatory penalties. Integrity compromises could allow attackers to alter records, impacting operational reliability and trust. Availability may also be affected if attackers execute destructive queries or cause database corruption, disrupting library services. The remote, unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing the system to the internet or poorly segmented internal networks. The lack of current patches means organizations must rely on mitigation and monitoring to reduce risk. The reputational damage and potential legal consequences from data breaches further amplify the impact on European entities.

Organizations should immediately implement strict input validation and sanitization on the user_id parameter in /view_member.php, employing parameterized queries or prepared statements to prevent SQL injection. If source code modification is not feasible, deploying a web application firewall (WAF) with custom rules to detect and block SQL injection payloads targeting this endpoint is recommended. Network segmentation should be enforced to limit external access to the library management system, restricting it to trusted internal users where possible. Regularly monitor logs for suspicious query patterns or repeated access attempts to /view_member.php. Conduct thorough security assessments of the entire application to identify and remediate similar injection flaws. Engage with the vendor for official patches or updates and apply them promptly once available. Additionally, ensure backups of critical data are maintained securely to enable recovery in case of compromise. Educate staff on the risks and signs of exploitation attempts to enhance detection and response capabilities.
