Summary
In RustFS prior to 1.0.0-beta.12, FTPS MKD handling in FtpsDriver::mkd calls storage.create_bucket without authorize_operation for S3Action::CreateBucket, allowing authenticated FTPS users denied s3:CreateBucket to create buckets.
Risk Assessment
Risk of unauthorized resource creation, which could lead to uncontrolled data growth, costs, or security policy violations.
Recommendation
Update RustFS to version 1.0.0-beta.12 or later, which includes the fix. Ensure that FTPS operations are properly authorized.
