Critical [CVE-2026-70398] GitOpsCluster.spec.argoServer.argoNamespace writes spoke bearer tokens to attacker-chosen namespace
CVE-2026-70398Source published Source updated
A flaw was found in multicloud-integrations, a component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows an authenticated user, referred to as a tenant, to manipulate the GitOpsCluster controller. By exploiting this, a tenant can redirect sensitive spoke cluster bearer tokens from secure locations to a namespace they control. This unauthorized access to tokens can lead to the disclosure of critical information and bypass security policies within ArgoCD AppProjects. This is due to the GitOpsCluster controller writing secrets to an attacker-chosen namespace, bypassing existing security guards, leading to privilege escalation and circumvention of ArgoCD AppProject constraints. Red Hat severity: Important — CVSS 9.6 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N).…
