A fix is available — apply it.

A flaw was found in the must-gather component of Red Hat Advanced Cluster Management for Kubernetes. Certain ACM wrapper Custom Resources that embed Secret data are collected without redaction. When an administrator runs must-gather, credentials and tokens are captured in cleartext in the resulting archive, potentially exposing sensitive information to anyone with access to the archive.
