MinIO is a High Performance Object Storage. When someone creates an access key, it inherits the permissions of the parent key. Not only for

admin rights are denied, access keys will be able to simply override their own
s3 permissions to something more permissive. The vulnerability is fixed in RELEASE.2024-01-31T20-20-33Z.
