This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 2.1% (81st percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. A security issue was found where an non-admin user is able to create service accounts for root or other admin users and then is able to assume their access policies via the generated credentials. This in turn allows the user to escalate privilege to that of the root user. This vulnerability has been resolved in pull request #14729 and is included in RELEASE.2022-04-12T06-55-35Z. Users unable to upgrade may workaround this issue by explicitly adding a admin:CreateServiceAccount deny policy, however, this, in turn, denies the user the ability to create their own service accounts as well.
