CVE-2025-68587 identifies a missing authorization vulnerability in the Bob Watu Quiz plugin, which is widely used for creating quizzes on WordPress sites. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to perform actions that should be restricted. This could include viewing, modifying, or deleting quiz content or results without proper permissions. The affected versions include all versions up to and including 3.4.5, although the exact range is not fully specified. The vulnerability does not require user interaction but does rely on the attacker accessing the vulnerable plugin interface. No public exploits have been reported yet, and no official patch links are provided at the time of publication. The lack of a CVSS score necessitates an independent severity assessment based on the potential impact on confidentiality, integrity, and availability, as well as ease of exploitation and scope. The vulnerability could compromise sensitive educational data and undermine trust in e-learning platforms using this plugin. Since Watu Quiz is a WordPress plugin, the threat surface includes any WordPress-based sites using this plugin, which are common in educational and training sectors.

For European organizations, especially educational institutions, e-learning providers, and training platforms that use the Watu Quiz plugin, this vulnerability poses a significant risk. Unauthorized access could lead to exposure or manipulation of quiz content, user scores, and potentially sensitive user data. This could result in reputational damage, loss of user trust, and compliance issues with data protection regulations such as GDPR. The integrity of educational assessments could be compromised, affecting academic outcomes and certification processes. Additionally, if attackers leverage this vulnerability as a foothold, it could lead to broader network compromise. The impact is heightened in countries with widespread adoption of WordPress for educational purposes and where digital learning is integral to institutional operations.

Organizations should immediately audit their WordPress installations to identify if Watu Quiz plugin versions up to 3.4.5 are in use. Until an official patch is released, restrict access to the plugin’s administrative and quiz management interfaces to trusted users only, using strong authentication and role-based access controls. Implement web application firewalls (WAFs) with rules to detect and block unauthorized access attempts targeting the plugin endpoints. Monitor logs for unusual activity related to quiz management functions. Educate administrators on the risks of misconfigured access controls and enforce the principle of least privilege. Once a patch becomes available, apply it promptly. Consider isolating the quiz functionality on separate subdomains or environments to limit potential lateral movement. Regularly back up quiz data to enable recovery in case of tampering.
