The WP Maps Pro plugin for WordPress is vulnerable to Privilege Escalation via Administrator Account Creation in all versions up to, and including, 6.1.0. This is due to the wpgmp_temp_access_ajax AJAX action being registered with wp_ajax_nopriv_ and protected only by a nonce check using the fc-call-nonce nonce, which is publicly embedded into every frontend page via wp_localize_script as the nonce field of the wpgmp_local JavaScript object, rendering the check ineffective as an access control mechanism. This makes it possible for unauthenticated attackers to invoke the wpgmp_temp_access_support handler with check_temp=false, which unconditionally creates a new WordPress user with the hardcoded role of administrator via wp_insert_user() and returns a magic login URL that, when visited, calls wp_set_auth_cookie() to fully authenticate the attacker as the newly created administrator, resulting in complete site takeover.
