WP Human Resource Management 2.0.0 - 2.2.17 - Missing Authorization to Authenticated (Employee+) Privilege Escalation via wp_ajax_hrm_insert_employee AJAX Action

The WP Human Resource Management plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization in the ajax_insert_employee() and update_empoyee() functions in versions 2.0.0 through 2.2.17. The AJAX handler reads the client-supplied $_POST['role'] and, after basic cleaning via hrm_clean(), passes it directly to wp_insert_user() and later to $user->set_role() without verifying that the current user is allowed to assign that role. This makes it possible for authenticated attackers, with Employee-level access and above, to elevate their privileges to administrator.

WP Human Resource Management 2.0.0 - 2.2.17 - Missing Authorization to Authenticated (Employee+) Arbitrary User Deletion via ajax_delete_employee Function

The WP Human Resource Management plugin for WordPress is vulnerable to Arbitrary User Deletion due to a missing authorization within the ajax_delete_employee() function in versions 2.0.0 through 2.2.17. The plugin’s deletion handler reads the client-supplied $_POST['delete'] array and passes each ID directly to wp_delete_user() without verifying that the caller has the delete_users capability or limiting which user IDs may be removed. This makes it possible for authenticated attackers, with Employee-level access and above, to delete arbitrary accounts, including administrators.

The WP Human Resource Management plugin before 2.2.6 for WordPress does not ensure that a leave modification occurs in the context of the Administrator or HR Manager role.
