CVE-2025-67976 identifies a missing authorization vulnerability in the Bob Watu Quiz plugin, versions up to and including 3.4.5. This vulnerability stems from improperly configured access control mechanisms that fail to enforce security levels correctly, allowing unauthorized users to bypass restrictions and perform actions they should not be permitted to do. The vulnerability is categorized as an access control flaw, which can lead to unauthorized data exposure, modification, or potentially disruption of quiz functionalities. The plugin is commonly used in WordPress environments to create and manage quizzes, often in educational or training contexts. Since the vulnerability does not require authentication or user interaction explicitly, it could be exploited remotely if the plugin is publicly accessible. No patches or fixes have been linked yet, and no active exploits have been reported, indicating the vulnerability is newly disclosed. The absence of a CVSS score requires an assessment based on the nature of the flaw: missing authorization typically results in a high risk due to the potential for unauthorized access and data compromise. Organizations relying on Watu Quiz should monitor for vendor updates and consider interim controls to restrict access and monitor suspicious activity.

For European organizations, especially those in education, training, and e-learning sectors using the Watu Quiz plugin, this vulnerability poses a significant risk to the confidentiality and integrity of quiz data. Unauthorized access could lead to exposure of sensitive user information, manipulation of quiz results, or disruption of learning processes. This could damage organizational reputation, violate data protection regulations such as GDPR, and impact operational continuity. Since Watu Quiz is a WordPress plugin, organizations with publicly accessible WordPress sites are particularly vulnerable. The impact extends to any entity relying on the plugin for assessments, certification, or training, potentially undermining trust in digital learning platforms. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once details become widely known.

1. Monitor official Bob Watu Quiz plugin channels for patches or updates addressing CVE-2025-67976 and apply them promptly once available. 2. Restrict access to the Watu Quiz plugin administration and management interfaces to trusted users only, using WordPress role management and access control plugins. 3. Implement web application firewalls (WAF) with rules to detect and block unauthorized access attempts targeting quiz management endpoints. 4. Conduct regular audits of user permissions within WordPress to ensure no excessive privileges are granted. 5. Employ network segmentation to isolate critical learning management systems and limit exposure to the internet. 6. Enable logging and monitoring of quiz-related activities to detect unusual or unauthorized actions quickly. 7. Consider temporarily disabling or replacing the plugin if immediate patching is not possible and the risk is deemed unacceptable. 8. Educate administrators about the risks of missing authorization vulnerabilities and the importance of strict access controls.
