Description
A flaw was identified in Argo CD, the GitOps engine used by Red Hat OpenShift GitOps, that could allow an unauthenticated attacker with network access to the Argo CD repo-server to achieve remote code execution. Under certain conditions, the attacker may then manipulate cached data to deploy malicious Kubernetes resources to managed clusters, potentially resulting in complete cluster compromise.
