Argo CD is a declarative continuous deployment for Kubernetes. Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored inkubectl.kubernetes.io/last-applied-configuration
annotation. pull request #7139 introduced the ability to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the kubectl.kubernetes.io/last-applied-configuration
annotation which includes full secret body. In order to view the cluster annotations via the Argo CD API, the user must have clusters, get
RBAC access. Note: In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as in bearer-token auth, the contents might be very sensitive. The bug has been patched in versions 2.8.3, 2.7.14, and 2.6.15. Users are advised to upgrade. Users unable to upgrade should update/deploy cluster secret with server-side-apply
flag which does not use or rely on kubectl.kubernetes.io/last-applied-configuration
annotation. Note: annotation for existing secrets will require manual removal.
