CVE-2026-70398
Multicloud-integrations: multicloud-integrations: gitopscluster.spec.argoserver.argonamespace writes spoke bearer tokens to attacker-chosen namespace
Description
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.
