RustFS: FTPS MKD bypasses IAM CreateBucket authorization

Published Aug 12, 2026 · Updated Aug 13, 2026 · Assigned by GitHub_M

Description

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, RustFS handles FTPS MKD in FtpsDriver::mkd in crates/protocols/src/ftps/driver.rs by calling storage.create_bucket without authorize_operation for S3Action::CreateBucket, allowing authenticated FTPS users denied s3:CreateBucket to create buckets. This issue is fixed in version 1.0.0-beta.12.
