CVE-2025-12707 identifies a SQL Injection vulnerability in the owthub Library Management System plugin for WordPress, affecting all versions up to and including 3.2.1. The vulnerability stems from improper neutralization of special elements in SQL commands (CWE-89), specifically due to insufficient escaping and lack of prepared statements for the 'bid' parameter. This parameter is user-supplied and directly incorporated into SQL queries without adequate sanitization, allowing attackers to append arbitrary SQL code. The vulnerability is exploitable remotely over the network without authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Exploitation can lead to unauthorized disclosure of sensitive information stored in the backend database, compromising confidentiality. While integrity and availability impacts are not indicated, the exposure of confidential data poses significant risks. No patches are currently linked, and no known exploits have been reported in the wild, but the vulnerability's characteristics suggest a high likelihood of exploitation once weaponized. The plugin’s widespread use in managing library resources on WordPress sites increases the attack surface, especially for organizations relying on this system for catalog and user data management.

For European organizations, particularly educational institutions, public libraries, and cultural heritage organizations using the owthub Library Management System plugin, this vulnerability poses a significant risk of data leakage. Sensitive information such as user records, borrowing histories, and internal catalog data could be exposed, potentially violating data protection regulations like GDPR. The breach of confidentiality could lead to reputational damage, legal penalties, and loss of trust among users. Since the vulnerability requires no authentication and no user interaction, attackers can automate exploitation at scale, increasing the risk of widespread data compromise. Additionally, organizations with interconnected systems might face secondary risks if attackers leverage extracted data for further attacks. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the high CVSS score underscores the urgency of addressing the issue.

1. Monitor for and apply official patches or updates from the owthub plugin vendor as soon as they become available. 2. In the absence of patches, implement Web Application Firewalls (WAFs) with rules specifically targeting SQL Injection patterns on the 'bid' parameter to block malicious payloads. 3. Restrict access to the vulnerable plugin endpoints by IP whitelisting or requiring authentication at the web server or application level to reduce exposure. 4. Conduct code reviews and, if feasible, modify the plugin source to use parameterized queries or prepared statements to properly sanitize inputs. 5. Regularly audit logs for suspicious SQL query patterns or unusual database access attempts. 6. Educate administrators on the risks and encourage timely updates of all WordPress plugins. 7. Employ network segmentation to isolate critical backend databases from direct web access. 8. Backup databases regularly and ensure backups are securely stored to enable recovery in case of compromise.
