**Description**
MinIO is a Multi-Cloud Object Storage framework. 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. This impacts all users of distributed deployments. Reports indicate this issue has been exploited in the wild, including a breach at Straumann Group, where sensitive data was exposed through an unsecured MinIO instance. The vulnerability allows attackers to potentially gain access to sensitive credentials. A POST request to the `/minio/bootstrap/v1/verify` endpoint can reveal these secrets. Approximately 105,895 systems are potentially exposed according to ZoomEye data.
