Prior to RELEASE.2023-03-20T20-16-18Z, an attacker can use crafted requests to bypass metadata bucket name checking and put an object into any bucket while processing `PostPolicyBucket`. To carry out this attack, the attacker requires credentials with `arn:aws:s3:::*` permission, as well as enabled Console API access. This issue has been patched in RELEASE.2023-03-20T20-16-18Z. As a workaround, enable browser API access and turn off `MINIO_BROWSER=off`.","state":0,"publishedAt":"2023-03-22T20:44:04.216+00:00","modifiedAt":"2025-10-21T23:15:22.302+00:00","affected":[{"ecosystem":"Vendor product","name":"minio","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"minio\",\n                    \"product\": \"minio\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< RELEASE.2023-03-20T20-16-18Z\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/minio/minio/security/advisories/GHSA-2pxw-r47w-4p8c","https://github.com/minio/minio/pull/16849","https://github.com/minio/minio/commit/67f4ba154a27a1b06e48bfabda38355a010dfca5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-28434","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-28434","identifiers":["CVE-2023-28434"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
