CVE-2025-66082 is a security vulnerability identified in the magepeopleteam WpEvently WordPress plugin, specifically affecting versions up to and including 5.0.4. The vulnerability arises from missing authorization checks, meaning that the plugin fails to properly enforce access control on certain functions or endpoints. This misconfiguration allows attackers to bypass intended security restrictions, potentially enabling unauthorized users to perform actions that should be limited to privileged roles such as administrators. The nature of the plugin, which manages event-related content and functionality within WordPress sites, means that exploitation could lead to unauthorized creation, modification, or deletion of event data, impacting the integrity and confidentiality of site content. The vulnerability does not currently have a CVSS score and no public exploits have been reported, but the lack of authorization checks inherently presents a significant risk. The issue affects all versions up to 5.0.4, with no patch links provided at this time. The vulnerability was published on November 21, 2025, and assigned by Patchstack. Because WordPress is widely used across Europe, and event management plugins are common in many organizational websites, this vulnerability poses a tangible threat to affected sites. Attackers do not require authentication or user interaction to exploit this flaw, increasing the risk profile. The absence of a patch necessitates immediate mitigation through access restrictions and monitoring until an official fix is released.

For European organizations, the impact of CVE-2025-66082 can be significant, especially for those relying on the WpEvently plugin to manage event-related content on their WordPress sites. Unauthorized access could lead to manipulation or deletion of event data, disrupting business operations, event scheduling, and communications. Confidential information related to events or attendees could be exposed or altered, undermining trust and potentially violating data protection regulations such as GDPR. The integrity of organizational websites could be compromised, damaging reputation and leading to potential financial losses. Since the vulnerability allows bypassing authorization without authentication, attackers can exploit it remotely and anonymously, increasing the likelihood of attacks. This is particularly concerning for sectors with high reliance on event management, including education, government, and corporate entities. The lack of a patch means organizations must rely on compensating controls, increasing operational overhead. Additionally, exploitation could serve as a foothold for further attacks within the network, escalating the overall security risk.

1. Immediately audit all WordPress sites to identify installations of the WpEvently plugin, especially versions up to 5.0.4. 2. Restrict access to WordPress administrative interfaces and event management pages using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3. Implement strict role-based access controls within WordPress to minimize the number of users with administrative privileges. 4. Monitor logs and network traffic for unusual activity related to event management endpoints or unauthorized access attempts. 5. Disable or uninstall the WpEvently plugin if it is not essential to reduce attack surface until a patch is available. 6. Stay informed through official vendor channels and security advisories for the release of a security update and apply patches promptly. 7. Employ security plugins that can detect and block unauthorized access attempts or suspicious behavior. 8. Conduct regular backups of website data and event information to enable recovery in case of compromise. 9. Educate site administrators about the risks and signs of exploitation related to this vulnerability. 10. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this plugin.
