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":"2023-03-22T21:15:18.427+00:00","modifiedAt":"2026-06-17T05:47:43.61+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","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/commit/67f4ba154a27a1b06e48bfabda38355a010dfca5","https://github.com/minio/minio/pull/16849","https://github.com/minio/minio/security/advisories/GHSA-2pxw-r47w-4p8c","https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2023-28434"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2023-28434","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-269","NVD-CWE-noinfo"],"productCriteria":["cpe:2.3:a:minio:minio:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2023-03-22T21:15:18.427","lastModified":"2026-06-17T05:47:43.610"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
