Title

Must-gather: must-gather: embedded secret data in acm wrapper crs collected without redaction

Summary

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.

Severity
