CVE-2025-25167 identifies a missing authorization vulnerability in the Black and White BookPress – For Book Authors plugin, a tool designed for authors to manage and publish books, typically integrated with WordPress environments. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to perform certain actions. This misconfiguration can allow an attacker to bypass authorization checks, potentially granting them unauthorized access to sensitive functions or data within the plugin. Affected versions include all releases up to and including 1.2.7. The vulnerability does not require user interaction, and while no exploits are currently known in the wild, the flaw presents a significant risk if weaponized. The lack of a CVSS score suggests this is a newly disclosed issue, with the technical details indicating that the core problem lies in the plugin’s access control logic rather than a code execution or injection flaw. The vulnerability could be exploited remotely if the attacker can reach the application interface, making it a critical concern for websites using this plugin for book publishing and author management.

The primary impact of CVE-2025-25167 is unauthorized access to restricted functionalities or data within the BookPress plugin. This can lead to confidentiality breaches, such as unauthorized viewing or extraction of unpublished manuscripts or author data, and integrity issues, including unauthorized modification or deletion of content. For organizations and individual authors relying on this plugin, exploitation could result in intellectual property theft, reputational damage, and potential loss of revenue. Since the vulnerability bypasses authorization controls, attackers might escalate privileges or perform administrative actions without proper credentials. The availability impact is likely limited but could occur if attackers disrupt plugin operations. Given the plugin’s role in content management, the risk extends to the broader website environment, potentially affecting the hosting WordPress site’s security posture.

To mitigate CVE-2025-25167, organizations should immediately monitor for updates or patches from the Black and White vendor and apply them as soon as they become available. In the interim, administrators should audit and tighten access control configurations within the plugin, ensuring that user roles and permissions are strictly enforced and tested. Implementing web application firewalls (WAF) with rules to detect and block unauthorized access attempts targeting the plugin’s endpoints can provide additional protection. Restricting access to the plugin’s administrative interfaces via IP whitelisting or VPNs can reduce exposure. Regular security assessments and penetration testing focusing on authorization logic are recommended to detect similar misconfigurations. Additionally, maintaining comprehensive logging and monitoring can help identify suspicious activities related to unauthorized access attempts.
