RustFS is a distributed object storage system built in Rust. RustFS authorizes explicit versionId reads in GetObject, CopyObject sources, and UploadPartCopy sources with s3:GetObject instead of s3:GetObjectVersion, allowing principals without historical-version permission to disclose known historical object content. This issue is fixed in version 1.0.0-beta.11.
