Title
Gitops-operator: gitops-operator: missing allowednamespace check in reconcilerhook for clusterrole/role cases enables potential privilege escalation and dos
Summary
A flaw was found in the OpenShift GitOps operator. The ClusterRole reconciler does not validate resource ownership when reconciling ClusterRole objects. A namespace-scoped Argo CD instance can trigger deletion of a ClusterRole owned by a cluster-scoped Argo CD instance by crafting a name collision, resulting in a denial of service.
