CVE-2025-14736 is a critical vulnerability identified in the Frontend Admin by DynamiApps plugin for WordPress, affecting all versions up to and including 3.28.25. The root cause is improper privilege management (CWE-269) due to insufficient validation of user-supplied role values within the 'validate_value', 'pre_update_value', and 'get_fields_display' functions. This flaw allows an unauthenticated attacker to exploit a user registration form that includes a Role field to assign themselves the administrator role during registration. Because the vulnerability requires no authentication or user interaction, it enables a direct privilege escalation to full administrative control over the WordPress site. The CVSS v3.1 score of 9.8 reflects the vulnerability's critical nature, with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the ease of exploitation and potential impact make this a severe threat. The vulnerability compromises the core security model of WordPress sites using this plugin, potentially leading to site defacement, data theft, malware deployment, or complete site takeover.

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress sites with the Frontend Admin by DynamiApps plugin installed and user registration enabled. Attackers can gain full administrative privileges without authentication, leading to complete site compromise. This can result in data breaches involving sensitive customer or business data, disruption of services through defacement or denial of service, and use of compromised sites as platforms for further attacks such as phishing or malware distribution. Organizations in sectors with high regulatory requirements, such as finance, healthcare, and government, face additional compliance and reputational risks. The public-facing nature of many WordPress sites in Europe increases exposure, particularly if registration forms are accessible and not restricted. The lack of current known exploits provides a window for proactive mitigation, but the critical severity demands urgent attention.

Immediate mitigation steps include disabling or restricting access to user registration forms that allow role assignment until a patch is available. Administrators should audit their WordPress installations to identify the presence of the Frontend Admin by DynamiApps plugin and verify if user registration with role selection is enabled. Implementing Web Application Firewall (WAF) rules to block suspicious registration attempts or requests containing role parameters can reduce risk. Monitoring logs for unusual registration activity or privilege escalations is essential. Once the vendor releases a patch, prompt application is critical. Additionally, organizations should enforce the principle of least privilege by limiting the roles available for assignment during registration and consider alternative user management workflows that do not expose role parameters to unauthenticated users. Regular backups and incident response plans should be updated to address potential exploitation scenarios.
