Summary

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.

Risk Assessment

Attackers can access, delete, or upload files belonging to other users, leading to breaches of data confidentiality, integrity, and availability.

Recommendation

Update MateCloud to a version later than 5.0.8 if available, or implement access controls on the /api/v1/admin/storage endpoints. Also verify user permissions and audit object storage operations.
