CVE-2025-14736 is a critical vulnerability classified under CWE-269 (Improper Privilege Management) found in the Frontend Admin by DynamiApps plugin for WordPress. The vulnerability affects all versions up to and including 3.28.25. It stems from insufficient validation of user-supplied role values within the plugin's 'validate_value', 'pre_update_value', and 'get_fields_display' functions. These functions fail to properly verify the legitimacy of role assignments during user registration or profile updates. Consequently, an unauthenticated attacker who can access a user registration form containing a Role field can manipulate the role parameter to assign themselves administrator privileges. This bypasses normal access controls and authentication mechanisms, granting full administrative control over the WordPress site. The vulnerability is remotely exploitable over the network without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact includes complete compromise of confidentiality, integrity, and availability of the affected site. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make this a high-risk vulnerability. The plugin is widely used in WordPress environments, increasing the potential attack surface. The lack of available patches at the time of publication necessitates immediate defensive actions by administrators.

For European organizations, this vulnerability poses a severe threat due to the widespread use of WordPress as a content management system across government, education, healthcare, and private sectors. Successful exploitation leads to full site compromise, allowing attackers to steal sensitive data, deface websites, deploy malware, or pivot to internal networks. The ability to escalate privileges without authentication increases the risk of automated mass exploitation campaigns. Organizations relying on the Frontend Admin by DynamiApps plugin for user management or frontend customization are particularly vulnerable. The impact extends to reputational damage, regulatory non-compliance (e.g., GDPR breaches due to data exposure), and operational disruption. Given the criticality, European entities with public-facing WordPress sites must prioritize remediation to prevent potential large-scale attacks targeting critical infrastructure and services.

1. Immediately restrict or disable access to any user registration forms that include a Role field until the vulnerability is patched. 2. Remove or deactivate the Frontend Admin by DynamiApps plugin if it is not essential. 3. Monitor WordPress user accounts for unauthorized administrator account creation and unusual role changes. 4. Implement web application firewalls (WAFs) with custom rules to block requests attempting to manipulate role parameters in registration forms. 5. Apply principle of least privilege by limiting plugin usage and administrative access to trusted personnel only. 6. Stay alert for official patches or updates from DynamiApps and apply them promptly once available. 7. Conduct thorough security audits of WordPress installations to identify and remediate similar privilege escalation risks. 8. Educate site administrators on the risks of exposing role assignment fields in frontend forms. 9. Employ multi-factor authentication for all administrator accounts to reduce impact of compromised credentials. 10. Regularly back up website data and configurations to enable rapid recovery in case of compromise.
