Until a fix is available, restrict issuance and use of admin-type API tokens and monitor for unusual administrative API activity.
Description
ThinkCMF versions up to 8.0.1 have an incorrect authorization vulnerability in the RestAdminBaseController. This flaw allows backend administrators with restricted privileges to bypass authorization checks because Auth::check() fails open when no admin_api rule is defined. Attackers possessing a valid admin-type API token can exploit this to access all admin REST API endpoints, including listing member emails and mobile numbers, disabling members, and elevating their privileges to full administrator rights.
