MinIO versions before RELEASE.2020-04-23T00-58-49Z have an authentication bypass issue in the MinIO admin API. Given an admin access key, it is possible to perform admin API operations i.e. creating new service accounts for existing access keys - without knowing the admin secret key. This has been fixed and released in version RELEASE.2020-04-23T00-58-49Z.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact total (CVSS ≥ 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
