CVE-2025-2907 is a critical vulnerability affecting the WordPress plugin 'Order Delivery Date' in versions prior to 12.3.1, specifically version 2.0 as noted. The vulnerability stems from missing authorization and Cross-Site Request Forgery (CSRF) protections during the import of plugin settings. Additionally, the plugin fails to restrict updates solely to its own configuration options, allowing attackers to manipulate unrelated WordPress options. Exploiting this flaw, an attacker can modify the 'default_user_role' option to 'administrator' and enable 'users_can_register', effectively permitting arbitrary user registration with administrative privileges. This leads to a complete site takeover without requiring any authentication or user interaction. The CVSS 3.1 base score is 9.8 (critical), reflecting the vulnerability's ease of remote exploitation over the network (AV:N), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (all high). The underlying weaknesses correspond to CWE-862 (Missing Authorization) and CWE-352 (Cross-Site Request Forgery). No known exploits in the wild have been reported yet, but the vulnerability's nature and severity make it a high-risk target for attackers aiming to compromise WordPress sites using this plugin. The absence of authorization checks and CSRF protections during settings import is a critical design flaw, allowing attackers to escalate privileges and gain full control over affected websites.

For European organizations using the Order Delivery Date WordPress plugin, this vulnerability poses a severe risk of complete website compromise. Attackers can gain administrative access remotely without authentication, enabling them to manipulate site content, steal sensitive data, deploy malware, or use the site as a pivot point for further attacks within the organization's network. This can lead to reputational damage, data breaches involving customer or employee information, and potential regulatory non-compliance under GDPR due to unauthorized data access or modification. E-commerce and service-oriented websites relying on WordPress are particularly vulnerable, as attackers could disrupt business operations or conduct fraudulent activities. The lack of user interaction or authentication requirements lowers the barrier for exploitation, increasing the likelihood of automated attacks targeting vulnerable sites. Given WordPress's widespread use in Europe, especially among small and medium enterprises, the impact can be extensive if timely mitigation is not applied.

1. Immediate update of the Order Delivery Date plugin to version 12.3.1 or later where the vulnerability is patched. 2. If updating is not immediately possible, disable the plugin temporarily to prevent exploitation. 3. Implement Web Application Firewall (WAF) rules to detect and block unauthorized POST requests attempting to import settings or modify critical options. 4. Monitor WordPress user roles and registrations for unexpected administrator accounts and disable any suspicious accounts promptly. 5. Restrict access to the WordPress admin panel by IP whitelisting or VPN to reduce exposure. 6. Regularly audit plugin permissions and configurations to ensure no unauthorized changes occur. 7. Educate site administrators about the risks of importing settings from untrusted sources and enforce strict operational procedures for plugin management. 8. Employ security plugins that provide enhanced authorization and CSRF protections as an additional layer of defense. 9. Conduct periodic vulnerability scans focusing on WordPress plugins to detect outdated or vulnerable components proactively.
