CVE-2025-12407 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the 'Events Manager – Calendar, Bookings, Tickets, and more!' WordPress plugin developed by netweblogic. This vulnerability exists in all versions up to and including 7.2.2.2 due to missing or incorrect nonce validation on the 'location_delete' action. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and prevent unauthorized actions. The absence or improper implementation of nonce validation allows an attacker to craft a malicious request that, when executed by an authenticated administrator (via clicking a link or visiting a crafted webpage), can delete event locations without the administrator's explicit consent. This attack does not require the attacker to be authenticated but does require user interaction from a privileged user. The vulnerability affects the integrity of the event location data by enabling unauthorized deletion but does not compromise confidentiality or availability. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality or availability impact, and limited integrity impact. No patches or fixes are listed yet, and no known exploits have been reported in the wild as of the publication date. The vulnerability is categorized under CWE-352, which is a common web application security weakness related to CSRF attacks.

The primary impact of this vulnerability is on the integrity of event location data within affected WordPress sites using the vulnerable plugin. An attacker can cause unauthorized deletion of event locations by tricking an administrator into executing a malicious request. This can disrupt event management operations, cause data loss, and potentially affect business continuity for organizations relying on accurate event scheduling and location data. Since the attack requires user interaction from an administrator, the risk is somewhat mitigated but still significant in environments where administrators may be targeted via phishing or social engineering. There is no direct impact on confidentiality or availability, and no privilege escalation or remote code execution is involved. However, the disruption of event data can have operational and reputational consequences, especially for organizations that depend heavily on this plugin for customer engagement, ticketing, and event management.

To mitigate this vulnerability, organizations should immediately verify if they are using the affected versions of the 'Events Manager – Calendar, Bookings, Tickets, and more!' plugin and plan to update to a patched version once available. In the absence of an official patch, administrators can implement manual nonce validation on the 'location_delete' action by modifying the plugin code to include proper WordPress nonce checks (e.g., using wp_verify_nonce). Additionally, administrators should be trained to recognize phishing attempts and avoid clicking suspicious links, especially when logged into administrative accounts. Employing web application firewalls (WAFs) that can detect and block CSRF attack patterns may provide additional protection. Restricting administrative access to trusted networks and using multi-factor authentication can further reduce the risk of exploitation. Regular backups of event data should be maintained to enable recovery in case of unauthorized deletions.
