CVE-2025-49902 identifies a missing authorization vulnerability in the WordPress plugin 'Login Page Customizer – Customizer Login Page, Admin Page, Custom Design' developed by A WP Life. This plugin allows administrators to customize the WordPress login page and admin page designs. The vulnerability arises from improperly configured access control mechanisms that fail to verify whether a user is authorized to perform certain actions within the plugin's customization features. Specifically, unauthenticated attackers can exploit this flaw to manipulate or alter login page customizations without proper permissions. The CVSS 3.1 base score is 6.5 (medium severity), reflecting a network attack vector with low attack complexity, no privileges required, but requiring user interaction. The impact is primarily on integrity, as unauthorized changes to login pages can facilitate phishing attacks or mislead users, potentially leading to credential theft or further compromise. There is no direct impact on confidentiality or availability. The affected versions are all versions up to 2.1.1, with no patches currently linked. No known exploits have been reported in the wild, but the vulnerability's nature makes it a candidate for exploitation if left unmitigated. The issue was reserved in June 2025 and published in December 2025. Organizations using this plugin should monitor for official patches and consider temporary mitigations to restrict access to the plugin's customization interfaces.

For European organizations, the primary impact of CVE-2025-49902 lies in the potential for unauthorized modification of WordPress login pages, which can undermine user trust and facilitate phishing or social engineering attacks. This can lead to credential compromise, unauthorized access to internal systems, and subsequent data breaches. While the vulnerability does not directly expose sensitive data or disrupt service availability, the integrity compromise can have cascading effects on security posture. Organizations relying on WordPress sites for customer or employee portals are at risk of reputational damage and regulatory scrutiny under GDPR if user credentials or personal data are compromised as a result. The ease of exploitation (no privileges required) increases the risk, especially for public-facing sites. The lack of known exploits currently provides a window for proactive mitigation. However, failure to address this vulnerability could lead to targeted attacks against European entities, especially those in sectors with high reliance on WordPress for authentication interfaces.

1. Immediately audit and restrict access permissions to the Login Page Customizer plugin settings and customization interfaces, ensuring only trusted administrators have access. 2. Monitor web server logs for unusual requests targeting the plugin’s endpoints that could indicate exploitation attempts. 3. Implement Web Application Firewall (WAF) rules to block suspicious requests or patterns associated with unauthorized access attempts to the plugin. 4. Temporarily disable or uninstall the plugin if it is not critical to operations until a security patch is released. 5. Keep WordPress core and all plugins updated; apply the official patch from A WP Life as soon as it becomes available. 6. Educate site administrators about the risks of unauthorized login page modifications and encourage regular reviews of login page content. 7. Consider deploying multi-factor authentication (MFA) on WordPress logins to mitigate risks from credential theft stemming from phishing facilitated by this vulnerability. 8. Conduct regular security assessments of WordPress environments to detect and remediate similar access control issues.
