CVE-2026-111352
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
