Name of the Vulnerable Software and Affected Versions RustFS versions prior to 1.0.0-beta.12
Description RustFS handles FTPS MKD within the FtpsDriver::mkd() function in crates/protocols/src/ftps/driver.rs by calling storage.create bucket without performing an authorize operation for S3Action::CreateBucket. This allows authenticated FTPS users who have been denied the s3:CreateBucket permission to create buckets.
Recommendations Update RustFS to version 1.0.0-beta.12.
