Starting with RELEASE.2020-12-23T02-24-12Z and prior to RELEASE.2023-03-13T19-46-17Z, a user with consoleAdmin permissions can potentially create a user that matches the root credential accessKey. Once this user is created successfully, the root credential ceases to work appropriately. The issue is patched in RELEASE.2023-03-13T19-46-17Z. There are ways to work around this via adding higher privileges to the disabled root user via mc admin policy set.
