MinIO fails to filter the `\\` character, which allows for arbitrary object placement across buckets. As a result, a user with low privileges, such as an access key, service account, or STS credential, which only has permission to `PutObject` in a specific bucket, can create an admin user. This issue is patched in RELEASE.2023-03-20T20-16-18Z. There are no known workarounds.","state":0,"publishedAt":"2023-03-22T21:15:18.34+00:00","modifiedAt":"2026-06-17T05:47:42.33+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/8d6558b23649f613414c8527b58973fbdfa4d1b8","https://github.com/minio/minio/commit/b3c54ec81e0a06392abfb3a1ffcdc80c6fbf6ebc","https://github.com/minio/minio/releases/tag/RELEASE.2023-03-20T20-16-18Z","https://github.com/minio/minio/security/advisories/GHSA-w23q-4hw3-2pp6"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2023-28433","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-668","NVD-CWE-noinfo"],"productCriteria":["cpe:2.3:a:minio:minio:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2023-03-22T21:15:18.340","lastModified":"2026-06-17T05:47:42.330"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
