{"id":"CVE-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":["BIT-seaweedfs-2026-55873","GHSA-hgpf-8634-g44c","GO-2026-6329"],"modified":"2026-09-10T18:26:46.070106723Z","published":"2026-07-08T14:48:37Z","related":["openSUSE-SU-2026:21812-1"],"database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55873.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/seaweedfs/seaweedfs/releases/tag/4.34"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55873.json"},{"type":"ADVISORY","url":"https://github.com/seaweedfs/seaweedfs/security/advisories/GHSA-hgpf-8634-g44c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55873"},{"type":"FIX","url":"https://github.com/seaweedfs/seaweedfs/commit/b13463880c1fa62e255c058a9228b63cc95b4b36"},{"type":"FIX","url":"https://github.com/seaweedfs/seaweedfs/pull/9961"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/seaweedfs/seaweedfs","events":[{"introduced":"330bd92ddce763649d07e078d550cb03eda6a593"},{"fixed":"c6cf5a5bd7c87694c8d71ab41571f1412170ab2a"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"4.08"},{"fixed":"4.34"}]}}],"versions":["4.33","4.32","4.31","4.30","4.29","4.28","4.27","4.26","4.25","4.24","4.23","4.22","4.21","4.20","4.19","4.18","4.17","4.16","4.15","4.13","4.12","4.09","4.08"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55873.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
