The vulnerability identified as CVE-2025-12407 affects the 'Events Manager – Calendar, Bookings, Tickets, and more!' WordPress plugin developed by netweblogic. This plugin is widely used to manage event calendars, bookings, and ticketing functionalities on WordPress websites. The security issue is a Cross-Site Request Forgery (CSRF) vulnerability classified under CWE-352. The root cause is the absence or incorrect implementation of nonce validation on the 'location_delete' action within the plugin. Nonces are security tokens used to verify that a request originates from a legitimate user action within the site. Without proper nonce checks, an attacker can craft a malicious URL or form that, when visited or submitted by an authenticated administrator, triggers the deletion of event location data without their explicit consent. The attack vector requires no authentication from the attacker but does require the victim administrator to interact with the malicious content (e.g., clicking a link). The CVSS v3.1 base score is 4.3, indicating a medium severity level, with the vector string AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. This means the attack can be performed remotely over the network with low attack complexity, no privileges required, but user interaction is necessary. The impact is limited to integrity loss (unauthorized deletion of location data) without affecting confidentiality or availability. No known public exploits have been reported yet, and no patches or updates are linked in the provided data, suggesting that mitigation may require manual intervention or awaiting an official update. The vulnerability was published on December 12, 2025, and reserved on October 28, 2025, indicating recent discovery and disclosure.

For European organizations, especially those relying on WordPress for event management, this vulnerability can lead to unauthorized deletion of event location data, disrupting event scheduling, bookings, and ticketing operations. This could result in operational inefficiencies, loss of customer trust, and potential financial losses due to event mismanagement. While the vulnerability does not directly compromise sensitive data confidentiality or availability of the entire system, the integrity breach can undermine the reliability of event information presented to users and customers. Organizations running multi-administrator WordPress sites are particularly at risk since the attack depends on tricking an administrator into clicking a malicious link. The impact is more pronounced for businesses in sectors such as entertainment, hospitality, conferences, and cultural events, where accurate event data is critical. Additionally, the lack of known exploits currently reduces immediate risk but does not eliminate the threat of future exploitation. European regulatory frameworks like GDPR emphasize data integrity and operational reliability, so even integrity-focused attacks can have compliance implications if they affect service delivery or data accuracy.

1. Immediate mitigation involves educating WordPress site administrators to avoid clicking on suspicious links or visiting untrusted websites while logged into the WordPress admin panel. 2. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the 'location_delete' action or requests lacking valid nonces. 3. Restrict administrative access to trusted IP addresses or via VPN to reduce exposure to CSRF attacks. 4. Monitor logs for unusual deletion activities related to event locations to detect potential exploitation attempts early. 5. If possible, apply manual nonce validation patches or custom code to enforce nonce checks on the vulnerable action until an official plugin update is released. 6. Regularly check for and apply official plugin updates from netweblogic that address this vulnerability. 7. Employ Content Security Policy (CSP) headers to reduce the risk of malicious content injection that could facilitate CSRF attacks. 8. Consider implementing multi-factor authentication (MFA) for WordPress administrators to add an additional layer of security, although it does not directly prevent CSRF, it reduces overall account compromise risk. 9. Backup event data regularly to enable quick restoration in case of unauthorized deletions.
