MinIO Information Disclosure Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 12 May 2023). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

In a cluster deployment starting with RELEASE.2019-12-17T23-16-33Z and prior to RELEASE.2023-03-20T20-16-18Z, MinIO returns all environment variables, including `MINIO_SECRET_KEY` and `MINIO_ROOT_PASSWORD`, resulting in information disclosure.
