Affected versions of this package are vulnerable to Access Control Bypass through the exemption mechanism for raw S3 buckets in the hardening policy check. An attacker can deploy an unhardened S3 bucket without required security controls by pairing it with decoy sibling resources that reference a different bucket, causing the compliance check to pass incorrectly.
