Technical Analysis

CVE-2025-46485 is a Missing Authorization vulnerability (CWE-862) found in the WordPress plugin 'WP Customize Login Page' developed by Carlo La Pera. This vulnerability affects versions up to 1.6.5 of the plugin. The core issue is that certain functionality within the plugin is accessible without proper access control checks, meaning that unauthorized users can invoke functions or access features that should be restricted. This lack of authorization enforcement can allow attackers to perform actions or retrieve information that should be limited to authenticated or privileged users. The vulnerability does not require user interaction or authentication to be exploited, increasing its risk profile. Although no known exploits have been reported in the wild as of the publication date (April 24, 2025), the nature of the vulnerability suggests that exploitation could lead to unauthorized changes to login page customization or potentially other sensitive configurations managed by the plugin. Since the plugin customizes the WordPress login page, unauthorized access could also facilitate further attacks such as phishing or credential harvesting by altering login UI elements. The absence of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps by administrators using this plugin. The vulnerability is classified as medium severity, reflecting moderate impact balanced against the ease of exploitation and scope of affected systems.

Potential Impact

For European organizations using WordPress sites with the 'WP Customize Login Page' plugin, this vulnerability poses a risk of unauthorized modification of login page appearance and behavior. This can undermine user trust and potentially facilitate credential theft or social engineering attacks. Organizations in sectors with high reliance on web presence, such as e-commerce, media, education, and government services, may face reputational damage and operational disruptions. The unauthorized access could also be leveraged as a foothold for further attacks within the network, especially if the compromised WordPress instance integrates with internal systems or user databases. Given the widespread use of WordPress across Europe, even a medium severity vulnerability can have significant cumulative impact if exploited at scale. Additionally, regulatory frameworks such as GDPR impose strict requirements on protecting user data and system integrity, so exploitation leading to data breaches or unauthorized access could result in legal and financial penalties.

Mitigation Recommendations

1. Immediate removal or deactivation of the 'WP Customize Login Page' plugin until a security patch is released. 2. Monitor WordPress logs and web server access logs for unusual or unauthorized access attempts targeting the plugin's endpoints or functions. 3. Restrict access to WordPress admin interfaces via IP whitelisting or VPN to limit exposure. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests attempting to exploit missing authorization in the plugin. 5. Regularly audit installed plugins and themes for vulnerabilities and maintain an inventory to quickly respond to emerging threats. 6. Educate site administrators about the risks of unauthorized plugin functionality and encourage prompt updates once patches are available. 7. Consider alternative, well-maintained plugins for login page customization with verified security track records. 8. Employ multi-factor authentication (MFA) on WordPress admin accounts to reduce the risk of unauthorized access even if login page modifications occur. 9. Conduct penetration testing focused on plugin access controls to identify any other potential authorization weaknesses.
