This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 1.2%, top 34% of all CVEs by exploit prediction. 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 Kubernetes native application for cloud storage. All users on release RELEASE.2021-10-10T16-53-30Z are affected by a vulnerability that involves bypassing policy restrictions on regular users. Normally, checkKeyValid() should return owner true for rootCreds. In the affected version, policy restriction did not work properly for users who did not have service (svc) or security token service (STS) accounts. This issue is fixed in RELEASE.2021-10-13T00-23-17Z. A downgrade back to release RELEASE.2021-10-08T23-58-24Z is available as a workaround.
