NVD Description

Note: Versions mentioned in the description apply only to the upstream seaweedfs-cosi-driver package and not the seaweedfs-cosi-driver package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

SeaweedFS is a distributed storage system. In versions 4.08 through 4.33, requests signed with SigV4 service s3tables are routed to the S3Tables management API where authorization collapses account-less S3 identities into the shared admin account and fails open, allowing an authenticated low-privileged S3 user to enumerate administrator-owned table bucket names and ARNs. This issue is fixed in version 4.34.
