CVE-2026-73834
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.
Does this matter?
Lower severity and a low EPSS score (0.08%). Track it; it rarely justifies an emergency change on its own.
Description
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.
