CVE-2025-3064

Description: The WPFront User Role Editor plugin, versions up to and including 4.2.1, is vulnerable to Cross-Site Request Forgery (CSRF) in the whitelist_options() function due to missing or insufficient nonce validation.
Severity: High (CVSS Score: 8.8)
Exploit: An unauthenticated attacker can craft a malicious request that, when triggered by a logged-in administrator (specifically on a WordPress multisite instance), updates the default user role option. This can lead to privilege escalation, potentially allowing the attacker to create new administrator accounts or modify site settings. This requires tricking an administrator into performing an action like clicking a malicious link.

Immediate Update: Upgrade the WPFront User Role Editor plugin to the latest available version (greater than 4.2.1) as soon as possible. The update should include proper nonce validation to prevent CSRF attacks.
User Awareness Training: Educate administrators about the risks of CSRF attacks and the importance of avoiding suspicious links or requests. Emphasize the need to verify the authenticity of requests before taking any action.
Monitor User Roles: Regularly review user roles and permissions, particularly after applying updates or making changes to user management plugins. Look for unexpected or unauthorized role assignments.
Web Application Firewall (WAF) Rules: If using a Web Application Firewall (WAF), consider implementing custom rules to detect and block potentially malicious requests targeting the whitelist_options() function or similar user role management functionalities. This serves as an additional layer of defense.
Nonce Validation Review (For Developers): If developing or maintaining WordPress plugins, carefully review and ensure proper implementation of nonce validation for all administrative actions. Use WordPress’s built-in nonce functions (wp_nonce_field, wp_verify_nonce) correctly.
