CVE-2026-111352 Details
Description
ThinkCMF through 8.0.1 contains an incorrect authorization vulnerability in RestAdminBaseController that allows restricted backend administrators to call every admin REST API endpoint because Auth::check() fails open when no admin_api rule exists. Attackers with a valid admin-type API token can list member emails and mobile numbers, disable members, and call PUT admin/roles/{id}/authorize to grant themselves full administrator rights.
A vulnerability allowing incorrect authorization has been identified in ThinkCMF versions through 8.0.1. This issue resides within the RestAdminBaseController, where the authorization check fails open for backend administrators. The flaw allows restricted admins to access all admin REST API endpoints because the authorization function, Auth::check(), does not properly validate permissions when no admin_api rule is assigned. As a result, attackers with a valid admin API token can exploit this to access sensitive member information, disable accounts, and manipulate role authorizations to gain full administrative rights.
Users are advised to manually insert 'admin_api:' rule names into the 'auth_rule' table or to update to a patched version of ThinkCMF that addresses this authorization flaw.
