CVE-2025-64249 identifies a missing authorization vulnerability in the Protect WP Admin plugin developed by WP-EXPERTS.IN, which is designed to protect WordPress administrative interfaces. The vulnerability arises from incorrectly configured access control security levels, allowing attackers to bypass authorization checks that should restrict access to sensitive admin functionalities. This flaw affects all versions up to and including 4.1. Without proper authorization enforcement, an attacker could potentially perform unauthorized administrative actions such as modifying site settings, installing malicious plugins, or accessing sensitive data. The vulnerability was reserved in late October 2025 and published in mid-December 2025, with no current public exploits reported. The lack of a CVSS score necessitates an independent severity assessment. Given that the vulnerability compromises access control—a critical security boundary—and does not require user interaction or authentication to exploit, it poses a significant risk to the confidentiality and integrity of affected WordPress sites. The scope is limited to sites using the vulnerable plugin, but given WordPress's widespread use, the potential impact is broad. The vulnerability is particularly concerning for organizations relying on Protect WP Admin for securing their WordPress admin areas, as it undermines the plugin’s core protective function.

For European organizations, the impact of CVE-2025-64249 could be substantial, especially for those with WordPress-based websites using the Protect WP Admin plugin. Unauthorized access to WordPress admin panels can lead to site defacement, data breaches, insertion of malware or ransomware, and disruption of business operations. This can damage brand reputation, lead to regulatory non-compliance (e.g., GDPR violations due to data exposure), and cause financial losses. Organizations in sectors such as e-commerce, government, finance, and media are particularly vulnerable due to the sensitive nature of their web content and data. The vulnerability could also be leveraged as a foothold for lateral movement within corporate networks if the WordPress server is integrated with internal systems. Given the plugin’s role in protecting admin access, its compromise effectively nullifies a critical security control, increasing the attack surface significantly.

1. Immediately audit all WordPress installations to identify the use of Protect WP Admin plugin versions up to 4.1. 2. If possible, update the plugin to a patched version once available; if no patch exists, consider disabling or uninstalling the plugin temporarily. 3. Implement IP whitelisting to restrict access to WordPress admin URLs only to trusted IP addresses. 4. Deploy multi-factor authentication (MFA) for all WordPress admin accounts to add an additional security layer. 5. Use web application firewalls (WAFs) to detect and block unauthorized access attempts targeting admin endpoints. 6. Monitor server and application logs for unusual access patterns or failed authorization attempts. 7. Harden WordPress installations by limiting plugin usage to trusted and actively maintained plugins. 8. Educate administrators about the risks and signs of compromise related to admin panel access. 9. Consider network segmentation to isolate web servers from critical internal systems to limit lateral movement if compromised.
