{"id":"BIT-seaweedfs-2026-55873","summary":"SeaweedFS: Improper authorization in the S3Tables / Iceberg REST management API lets a low-privileged S3 user enumerate administrator-owned table buckets","details":"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.","aliases":["CVE-2026-55873","GHSA-hgpf-8634-g44c","GO-2026-6329"],"modified":"2026-09-02T19:56:01.622890232Z","published":"2026-07-14T08:55:19.859Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:seaweedfs:seaweedfs:*:*:*:*:*:go:*:*"]},"references":[{"type":"WEB","url":"https://github.com/seaweedfs/seaweedfs/commit/b13463880c1fa62e255c058a9228b63cc95b4b36"},{"type":"WEB","url":"https://github.com/seaweedfs/seaweedfs/pull/9961"},{"type":"WEB","url":"https://github.com/seaweedfs/seaweedfs/releases/tag/4.34"},{"type":"WEB","url":"https://github.com/seaweedfs/seaweedfs/security/advisories/GHSA-hgpf-8634-g44c"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55873"}],"affected":[{"package":{"name":"seaweedfs","ecosystem":"Bitnami","purl":"pkg:bitnami/seaweedfs"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.34.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/seaweedfs/BIT-seaweedfs-2026-55873.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.5"}
