DescriptionCVE.org

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 3.28.36. This is due to insufficient authorization checks in the role field update mechanism combined with overly permissive capabilities for the admin_form post type. The admin_form custom post type uses 'capability_type' => 'page', which grants editors the ability to create and edit forms. When an editor creates an edit_user form, they can manipulate the form configuration to include 'administrator' in the role_options array by directly submitting POST data to wp-admin/post.php, bypassing the UI restrictions in feadmin_get_user_roles(). When the form is subsequently submitted, the pre_update_value() function in class-role.php only validates that the submitted role exists in the form's role_options array (lines 107-110), but fails to verify that the current user has permission to assign that specific role. This makes it possible for unauthenticated attackers to first register as editors (via a public new_user form), then create an edit_user form with administrator in the allowed roles, and finally use that form to escalate their own privileges to administrator.

AnalysisAI

Privilege escalation in Frontend Admin by DynamiApps plugin allows authenticated attackers with editor-level access to elevate privileges to administrator. The vulnerability exists due to insufficient authorization checks when configuring user role options in edit_user forms combined with overly permissive capabilities on the admin_form post type. Attackers can bypass UI restrictions by directly manipulating POST data to include 'administrator' in role_options, then use the crafted form to assign themselves administrator privileges. CVSS 8.8 reflects network-accessible, low-complexity exploitation requiring only low privileges (editor account). No public exploit code identified at time of analysis, though the attack chain is straightforward for authenticated users. EPSS data not provided, but the technical barrier is minimal once editor access is obtained.

Technical ContextAI

This vulnerability affects the Frontend Admin by DynamiApps WordPress plugin (CPE: cpe:2.3:a:shabti:frontend_admin_by_dynamiapps), specifically its role assignment mechanism in user management forms. The root cause (CWE-269: Improper Privilege Management) stems from two architectural flaws: (1) The admin_form custom post type uses 'capability_type' => 'page', which grants WordPress editors the edit_pages capability, allowing them to create and modify admin forms. (2) The pre_update_value() function in class-role.php validates only that the submitted role exists in the form's role_options array but fails to verify whether the current user has sufficient privileges to assign that specific role. The plugin's feadmin_get_user_roles() UI function filters available roles, but this client-side restriction is bypassed when attackers directly POST data to wp-admin/post.php. WordPress's built-in role hierarchy (subscriber < contributor < author < editor < administrator) should prevent lower-privileged users from assigning higher roles, but the plugin's custom form handling bypasses these native protections.

RemediationAI

Immediately update Frontend Admin by DynamiApps to version 3.28.37 or later, which addresses the privilege escalation vulnerability per changeset 3519460 documented at https://plugins.trac.wordpress.org/changeset/3519460. The patch implements proper authorization checks in the role assignment mechanism to verify that users have sufficient privileges before allowing role escalation. Until patching is complete, implement these compensating controls: (1) Disable public user registration in WordPress (Settings → General → Membership: uncheck 'Anyone can register') to prevent the unauthenticated attack path-this eliminates the most severe exploitation scenario but does not address risk from existing compromised editor accounts. (2) If registration must remain enabled, configure new_user forms to assign only subscriber or contributor roles, never editor or above-this breaks the initial access requirement in the attack chain. (3) Audit existing user accounts for unexpected privilege escalations by reviewing Users list for recently created administrator accounts and checking admin activity logs if available. (4) Restrict editor access to the admin_form post type by implementing custom capability filters, though this requires code modification and may break legitimate plugin functionality. Note that workarounds (1) and (2) prevent new exploitation but do not remove the underlying vulnerability-patching remains the definitive solution.
