Description
MateCloud through 5.0.8 contains a missing authorization vulnerability that allows any authenticated user to manage object storage by calling the unprotected /api/v1/admin/storage endpoints in StorageController. Low-privilege or self-registered users can supply arbitrary bucket and objectName values to list objects, obtain pre-signed download URLs for other users' files, delete objects, and upload at chosen keys.
