CVE-2021-43858
Date: December 27, 2021
MinIO is a Kubernetes native application for cloud storage. Prior to version "RELEASE.2021-12-27T07-23-18Z", a malicious client can hand-craft an HTTP API call that allows for updating policy for a user and gaining higher privileges. The patch in version "RELEASE.2021-12-27T07-23-18Z" changes the accepted request body type and removes the ability to apply policy changes through this API. There is a workaround for this vulnerability: Changing passwords can be disabled by adding an explicit "Deny" rule to disable the API for users.
