CVE-2025-63030 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the New User Approve plugin developed by Saad Iqbal, affecting versions up to 3.2.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unintended actions on behalf of the user. In this case, the vulnerability allows an attacker to induce an authenticated administrator or user with approval privileges to approve new user registrations without their knowledge or consent. The CVSS 3.1 score of 7.1 reflects a high severity, with attack vector being network (remote), low attack complexity, no privileges required, but requiring user interaction. The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability losses, meaning that unauthorized user approvals could lead to unauthorized access or privilege escalation, potentially compromising the system's integrity and availability. No patches or known exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is commonly used in WordPress environments to manage user registrations, making it a target for attackers seeking to bypass user approval workflows.

For European organizations, especially those relying on WordPress and the New User Approve plugin to manage user registrations, this vulnerability poses a significant risk. Unauthorized approval of new users can lead to unauthorized access, privilege escalation, and potential lateral movement within networks. This can compromise sensitive data confidentiality and system integrity, and may disrupt availability if malicious users perform destructive actions. Organizations in sectors with strict compliance requirements, such as finance, healthcare, and government, face increased risks of regulatory penalties and reputational damage. The vulnerability's ease of exploitation via social engineering or malicious websites increases the attack surface. Additionally, the cross-site nature of the attack can affect users across different domains, complicating detection and response. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the public disclosure increases the risk of future exploitation attempts.

Organizations should immediately assess their use of the New User Approve plugin and upgrade to a patched version once available. In the absence of an official patch, implement anti-CSRF tokens in the approval workflow to validate legitimate requests. Restrict user roles and permissions to minimize the number of users with approval capabilities. Employ web application firewalls (WAFs) with rules to detect and block suspicious CSRF attempts. Educate administrators and users about the risks of clicking on untrusted links while authenticated. Monitor logs for unusual approval activities and implement anomaly detection to identify unauthorized user approvals. Consider temporarily disabling the plugin or the approval feature if immediate patching is not feasible. Regularly review and update security policies related to user management and web application security. Finally, coordinate with plugin developers and security communities for updates and best practices.
