Doc Text:	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.	Story Points:	---

Description OSIDB Bzimport 2026-08-11 17:38:49 UTC

A flaw was found in the multicloud-integrations component of Red Hat Advanced Cluster Management (RHACM). The GitOpsCluster controller uses the tenant-controlled spec.argoServer.argoNamespace field to determine where spoke cluster bearer token Secrets are written. The controller copies ManagedServiceAccount tokens from privileged managed-cluster hub namespaces into the attacker-specified namespace. The only guard (VerifyArgocdNamespace) is bypassed by a tenant-settable annotation on the same CR. A tenant can exfiltrate spoke bearer tokens and bypass ArgoCD AppProject constraints.
