This is due to the add_user_in_waiting_list() function registered on the wp_ajax_yith_wcwtl_add_user action being missing both a capability check and a nonce verification, and using parse_str() + extract() to import attacker-controlled variables from $_POST['params'] that are then passed to wp_create_user() and $user->set_role(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator by creating a new user account and assigning it the administrator role.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
