CVE-2026-24954 identifies a deserialization of untrusted data vulnerability in the magepeopleteam WpEvently WordPress plugin, specifically versions up to and including 5.0.8. Deserialization vulnerabilities occur when untrusted input is deserialized by an application without proper validation, enabling attackers to inject malicious objects. In this case, the vulnerability allows object injection, which can lead to remote code execution, privilege escalation, or other malicious behaviors depending on the plugin's internal logic and the environment. WpEvently is a plugin used to manage events within WordPress sites, and its compromised state could allow attackers to manipulate event data, execute arbitrary code on the server, or pivot within the hosting environment. The vulnerability was reserved on January 28, 2026, and published on February 3, 2026, but no public exploits have been reported yet. No CVSS score has been assigned, and no official patches or mitigation links are currently available. The vulnerability requires no authentication and likely no user interaction, making it easier to exploit remotely if the plugin is active. The lack of known exploits suggests it is either newly discovered or not yet weaponized. However, the potential impact on confidentiality, integrity, and availability is significant due to the nature of object injection attacks in PHP-based WordPress plugins.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive event data, website defacement, or full server compromise if remote code execution is achieved. This could disrupt business operations, damage reputation, and lead to data breaches involving personal or corporate information. Organizations relying on WpEvently for event management, especially those handling large-scale or sensitive events, face increased risk. The impact is heightened for entities in sectors such as government, education, and large enterprises where WordPress is widely used and event data is critical. Additionally, compromised sites could be leveraged to distribute malware or conduct phishing campaigns targeting European users. The absence of patches increases the window of exposure, and the ease of exploitation without authentication raises the threat level. Overall, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of affected systems within Europe.

Organizations should immediately inventory their WordPress installations to identify the presence of the WpEvently plugin and its version. If the plugin is installed and version 5.0.8 or earlier is in use, disable or uninstall the plugin until a vendor patch is released. Monitor official magepeopleteam channels and trusted vulnerability databases for patch announcements. Implement web application firewalls (WAF) with rules to detect and block suspicious deserialization payloads or unusual POST requests targeting the plugin endpoints. Restrict access to WordPress admin interfaces and plugin files using IP whitelisting or VPNs to reduce exposure. Regularly back up WordPress sites and databases to enable recovery in case of compromise. Conduct security audits and penetration testing focused on deserialization vulnerabilities. Educate site administrators about the risks of installing unverified plugins and the importance of timely updates. Finally, consider deploying runtime application self-protection (RASP) solutions that can detect and block exploitation attempts in real time.
