| 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. |

Workarounds
CNA: Limit network access to the Argo CD repo-server gRPC endpoint to trusted internal components using Kubernetes NetworkPolicy or equivalent network access controls. Do not expose the repo-server outside the cluster or to untrusted networks. Restrict access to the associated Redis service and update to a fixed version once one becomes available.
There are currently no legacy QID mappings associated with this CVE.
