CVE-2025-49902 is a vulnerability classified as missing authorization in the WordPress plugin 'Login Page Customizer – Customizer Login Page, Admin Page, Custom Design' developed by A WP Life. The issue arises from improperly configured access control mechanisms within the plugin, allowing unauthorized users to access administrative customization features of the login page without proper authentication or authorization checks. This vulnerability affects all versions up to and including 2.1.1. The plugin is designed to allow administrators to customize the WordPress login page, including design and administrative settings. Due to the missing authorization, attackers can potentially manipulate these settings, which could lead to defacement, phishing, or further privilege escalation attacks if combined with other vulnerabilities. Although no known exploits have been reported in the wild, the risk remains significant because the vulnerability allows bypassing security controls that should restrict access to administrative functions. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity, but the nature of the flaw suggests a high risk. The vulnerability was reserved in June 2025 and published in December 2025, indicating recent discovery. The absence of patch links suggests that a fix may not yet be available, emphasizing the need for interim mitigations.

For European organizations, this vulnerability poses a significant risk especially for those relying on WordPress sites with the affected plugin installed. Unauthorized access to login page customization can lead to website defacement, phishing attacks by altering login interfaces, and potential privilege escalation if attackers leverage this access to inject malicious code or backdoors. This can compromise the confidentiality and integrity of user credentials and organizational data. The availability of the website could also be impacted if attackers disrupt login functionality. Given the widespread use of WordPress across Europe, organizations in sectors such as e-commerce, government, education, and media are particularly at risk. The impact is amplified in organizations that do not have strict access controls or monitoring on their WordPress administrative interfaces. Additionally, the absence of known exploits currently provides a window for proactive defense, but also means attackers may develop exploits soon after public disclosure.

European organizations should immediately audit their WordPress installations to identify if the 'Login Page Customizer – Customizer Login Page, Admin Page, Custom Design' plugin is installed and determine its version. If the plugin is present and version 2.1.1 or earlier is in use, organizations should consider disabling or uninstalling the plugin until a patch is released. Restrict access to WordPress administrative areas using IP whitelisting, multi-factor authentication, and strong password policies. Implement web application firewalls (WAFs) to detect and block unauthorized attempts to access plugin administrative endpoints. Monitor logs for unusual access patterns or changes to login page configurations. Stay informed about patch releases from the vendor and apply updates promptly once available. Additionally, consider isolating WordPress administrative interfaces behind VPNs or internal networks to reduce exposure. Conduct regular security assessments and penetration tests focusing on WordPress plugins and access controls.
