CVE-2026-14251 Red Hat CVE debrief
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. This HIGH severity vulnerability has a CVSS score of 7.7 and can be mitigated by applying the vendor's patch or update to the latest version of OpenShift GitOps operator.
