How broadly exploitable is this vulnerability?

Exploitation is possible wherever an attacker can obtain or compromise an identity that is intended to be limited to export-only IAM operations but can still reach the `ImportIam` admin API. It does not automatically grant access to unauthenticated users, but it breaks the separation between export and import permissions.

What level of access does an attacker need?

An attacker must have valid credentials or control over an account that has `ExportIAMAction` (or equivalent) permissions and network/API access to the RustFS admin interface. No additional special system privileges are required beyond that mis-scoped IAM role.

What is the safest general fix pattern?

The safest pattern is to ensure each IAM-related endpoint performs
