CVE-2025-66083 is a missing authorization vulnerability identified in the magepeopleteam WpEvently WordPress plugin, specifically affecting versions up to and including 5.0.4. The vulnerability arises from incorrectly configured access control security levels within the plugin, which is designed to manage event-related content on WordPress sites. Due to this misconfiguration, unauthorized users can exploit the plugin to access certain functionalities or data that should be restricted. The CVSS 3.1 score is 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact is limited to confidentiality (C:L), with no impact on integrity (I:N) or availability (A:N). This means attackers may be able to view some sensitive information without altering or disrupting the system. The vulnerability does not require authentication, increasing its risk profile, but does require some form of user interaction, such as clicking a crafted link or visiting a malicious page. No public exploits or patches are currently available, but the issue has been officially published and reserved in the CVE database. The plugin is commonly used in WordPress environments for event management, making websites relying on it potentially vulnerable to unauthorized data exposure.

For European organizations, the primary impact of CVE-2025-66083 is the potential unauthorized disclosure of sensitive event-related information managed via the WpEvently plugin. This could include event details, user registrations, or other confidential data stored or displayed by the plugin. While the vulnerability does not allow modification or disruption of services, the confidentiality breach could lead to reputational damage, privacy violations under GDPR, and potential exploitation by threat actors for further social engineering or targeted attacks. Organizations relying heavily on WordPress for event management, especially those in sectors like education, government, or large enterprises hosting public or private events, may face increased risk. The requirement for user interaction somewhat limits automated exploitation but does not eliminate risk, especially if attackers can lure users into triggering the vulnerability. The absence of known exploits reduces immediate threat but does not preclude future attacks once exploit code becomes available.

Organizations should monitor for official patches or updates from magepeopleteam and apply them promptly once released. In the interim, restrict access to the WpEvently plugin’s administrative and event management interfaces using web application firewalls (WAFs) or IP whitelisting to limit exposure. Implement strict role-based access controls within WordPress to minimize the number of users who can interact with the plugin. Educate users about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. Conduct regular security audits and vulnerability scans focusing on WordPress plugins. Consider disabling or replacing the WpEvently plugin with alternative event management solutions that have a stronger security posture if patching is delayed. Monitor logs for unusual access patterns or attempts to exploit the plugin. Finally, ensure compliance with GDPR by assessing and documenting the risk and response related to this vulnerability.
