Overview

github.com/minio/minio/cmd is an open source object storage server compatible with Amazon S3 APIs.

Affected versions of this package are vulnerable to Insecure Permissions. MinIO is an open-source high performance object storage service and it is API compatible with Amazon S3 cloud storage service. In MinIO before version RELEASE.2021-03-04T00-53-13Z it is possible to bypass a readOnly policy by creating a temporary 'mc share upload' URL. Everyone is impacted who uses MinIO multi-users. This is fixed in version RELEASE.2021-03-04T00-53-13Z. As a workaround, one can disable uploads with Content-Type: multipart/form-data as mentioned in the S3 API RESTObjectPOST docs by using a proxy in front of MinIO.

Note: This vulnerability resolved since version RELEASE.2021-03-04T00-53-13Z.
