A flaw was found in the must-gather component of Red Hat Advanced Cluster Management for Kubernetes. The cluster Proxy object is dumped in raw form, bypassing the oc inspect redaction that would normally sanitize sensitive fields. This exposes proxy basic-auth credentials in the must-gather archive, potentially disclosing sensitive authentication information to anyone with access to the archive.
To mitigate the risk of credential exposure, restrict access to must-gather archives to authorized personnel only. Before sharing must-gather archives, especially with external entities, manually inspect and redact any sensitive information, including proxy basic-auth credentials, from the cluster Proxy object within the archive.
