CVE-2025-63030 is a Cross-Site Request Forgery (CSRF) vulnerability found in the New User Approve plugin developed by Saad Iqbal, affecting all versions up to 3.2.0. The plugin is designed to manage and approve new user registrations on WordPress sites. The vulnerability arises because the plugin lacks proper CSRF protections, such as nonce tokens or other anti-CSRF mechanisms, on the user approval functionality. This flaw allows an attacker to craft a malicious web request that, when visited by an authenticated administrator, triggers the approval of new users without the administrator's explicit consent. Since the attack leverages the administrator's authenticated session, no additional authentication bypass is required, and no user interaction beyond visiting a malicious page is necessary. This can lead to unauthorized user accounts being approved, potentially granting attackers or malicious actors access to restricted areas of the affected site. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and unpatched, increasing the risk of exploitation. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the technical details suggest a significant risk to the integrity of user management processes. The plugin is commonly used in WordPress environments, which are prevalent in many European organizations for content management and business operations.

For European organizations, this vulnerability poses a significant risk to the integrity and security of their WordPress-based user management systems. Unauthorized approval of new users can lead to privilege escalation, unauthorized access to sensitive information, and potential lateral movement within the network. This is particularly concerning for organizations handling sensitive data or providing critical services through WordPress portals. The exploitation of this vulnerability could facilitate further attacks such as data exfiltration, installation of backdoors, or use of compromised accounts for phishing campaigns. The impact extends beyond confidentiality to integrity and availability, as unauthorized users could disrupt normal operations or introduce malicious content. Organizations with high administrative exposure or insufficient network segmentation are at greater risk. The absence of known exploits currently provides a window for proactive mitigation, but the public disclosure increases the urgency for remediation. European entities in sectors like government, finance, healthcare, and e-commerce, which rely heavily on WordPress for public-facing and internal applications, could face reputational damage and regulatory consequences if exploited.

To mitigate CVE-2025-63030, organizations should immediately review and restrict administrative access to the New User Approve plugin functionality, ensuring only trusted personnel have approval rights. Implementing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide an additional layer of defense. Administrators should avoid visiting untrusted websites while logged into WordPress admin accounts to reduce the risk of CSRF exploitation. Monitoring and logging of user approval actions should be enhanced to detect anomalous or unauthorized approvals promptly. If possible, apply manual patches or code modifications to introduce nonce verification or other CSRF tokens in the plugin’s approval workflows until an official patch is released. Organizations should also maintain up-to-date backups and have incident response plans ready in case of compromise. Regular security audits and penetration testing focused on WordPress plugins can help identify similar vulnerabilities proactively. Finally, educating administrators about CSRF risks and safe browsing practices is essential to reduce the likelihood of successful exploitation.
