Seaweedfs · Seaweedfs · CVE-2026-55873
**Name of the Vulnerable Software and Affected Versions**
SeaweedFS versions 4.08 through 4.33
**Description**
Requests signed with the SigV4 service `s3tables` are routed to the S3Tables management API. In this process, authorization collapses account-less S3 identities into a shared admin account and fails open. This allows an authenticated low-privileged S3 user to enumerate Amazon Resource Names (ARNs) and table bucket names owned by the administrator.
**Recommendations**
Update SeaweedFS to version 4.34.
