CVE-2026-24942 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the magepeopleteam WpEvently WordPress plugin, specifically affecting versions up to and including 5.1.1. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, causing the user’s browser to perform unwanted actions on a web application where they are logged in. In this case, the WpEvently plugin lacks adequate CSRF protections such as nonce tokens or proper validation of request origins, allowing attackers to craft malicious links or web pages that, when visited by an authenticated user, execute unauthorized commands on the WordPress site. This can lead to unauthorized changes in event data, plugin settings, or other administrative actions depending on the plugin’s capabilities. Although no public exploits have been reported yet, the vulnerability is publicly disclosed and documented in the CVE database. The absence of a CVSS score suggests that the vulnerability is newly identified and pending detailed severity assessment. The vulnerability affects a widely used WordPress plugin designed for event management, which is popular among organizations that rely on WordPress for their web presence. The attacker does not require user interaction beyond the victim visiting a malicious page, but the victim must be authenticated with sufficient privileges on the affected site. This vulnerability primarily impacts the integrity and potentially confidentiality of the affected systems by enabling unauthorized actions. The scope is limited to sites using the vulnerable plugin versions, but given WordPress’s widespread adoption, the potential reach is significant.

For European organizations, the impact of this CSRF vulnerability can be substantial, especially for those relying on WpEvently for managing events, registrations, or related content on WordPress sites. Successful exploitation could allow attackers to manipulate event details, disrupt event operations, or alter plugin configurations, potentially leading to misinformation, loss of trust, or operational disruptions. This could affect event organizers, educational institutions, cultural organizations, and businesses that use WordPress-based event management. Additionally, unauthorized changes could be leveraged as a foothold for further attacks, such as privilege escalation or data exfiltration, if combined with other vulnerabilities. The impact on confidentiality arises if sensitive event or user data is exposed or altered. The integrity of the website content and availability of event services could also be compromised, affecting user experience and organizational reputation. Given the reliance on WordPress in Europe and the critical role of event management in many sectors, this vulnerability poses a meaningful risk if left unaddressed.

To mitigate this vulnerability, organizations should first verify if they are using the WpEvently plugin version 5.1.1 or earlier. Immediate steps include: 1) Applying any available patches or updates from the vendor once released; 2) If no patch is available, temporarily disabling the plugin to prevent exploitation; 3) Implementing Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the plugin’s endpoints; 4) Enhancing site security by enforcing strong authentication and limiting user privileges to the minimum necessary; 5) Educating users about the risks of clicking unknown links while authenticated on administrative sites; 6) Monitoring logs for unusual POST requests or changes related to the plugin; 7) Reviewing and hardening the WordPress security posture overall, including ensuring that all plugins and core are up to date. Developers and site administrators should also consider adding nonce verification or other CSRF protections in custom plugin code. These measures go beyond generic advice by focusing on the specific plugin and its operational context.
