CVE-2025-14975 is a vulnerability classified under CWE-269 (Improper Privilege Management) found in the Custom Login Page Customizer WordPress plugin, specifically in versions prior to 2.5.4. The flaw arises from an insecure password reset process that does not properly authenticate or validate requests. An attacker who knows a valid username can send a limited number of unauthenticated requests to reset the password of that user, including administrator accounts. This allows the attacker to gain full access to the compromised account, leading to potential site takeover. The vulnerability has a CVSS v3.1 base score of 8.1, indicating high severity, with the vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, meaning it is remotely exploitable over the network but requires high attack complexity, no privileges, and no user interaction, and impacts confidentiality, integrity, and availability. No public exploits have been reported yet, but the risk remains significant due to the critical nature of the affected accounts. The vulnerability affects WordPress sites using the Custom Login Page Customizer plugin version 2.1.1 and earlier. The plugin is commonly used to customize login pages, making it popular among WordPress administrators seeking enhanced branding or user experience. The improper privilege management flaw could allow attackers to bypass intended security controls and reset passwords without proper authorization. This could lead to unauthorized administrative access, data theft, defacement, or further malware installation.

For European organizations, this vulnerability poses a significant risk to the security of WordPress-based websites, which are widely used across public, private, and governmental sectors. Successful exploitation could lead to unauthorized access to sensitive data, disruption of services, and reputational damage. Organizations relying on WordPress for e-commerce, customer portals, or internal applications could face financial losses and regulatory penalties under GDPR if personal data is compromised. The ability to reset passwords without authentication undermines trust in the affected systems and could facilitate further attacks such as privilege escalation, data exfiltration, or ransomware deployment. Given the plugin’s role in customizing login pages, attackers might also use the access to deploy phishing pages or malicious content. The high CVSS score reflects the broad impact on confidentiality, integrity, and availability, emphasizing the critical need for remediation. Although no known exploits are currently active, the vulnerability’s characteristics make it a likely target for attackers once publicized.

1. Immediately update the Custom Login Page Customizer plugin to version 2.5.4 or later, where the vulnerability is patched. 2. If immediate update is not possible, disable or remove the plugin temporarily to prevent exploitation. 3. Implement multi-factor authentication (MFA) on WordPress administrator accounts to add an additional security layer beyond passwords. 4. Monitor WordPress logs for unusual password reset requests or multiple failed login attempts, especially those targeting administrator accounts. 5. Restrict access to the WordPress admin and login pages using IP whitelisting or web application firewalls (WAF) to limit exposure. 6. Conduct regular security audits and vulnerability scans on WordPress installations to detect outdated plugins or suspicious activity. 7. Educate site administrators about the risks of using outdated plugins and the importance of timely patching. 8. Consider deploying intrusion detection/prevention systems (IDS/IPS) that can detect anomalous password reset patterns. 9. Backup WordPress sites regularly to enable quick recovery in case of compromise. 10. Review user accounts for unauthorized changes post-incident and reset passwords if suspicious activity is detected.
