Red Hat Advanced Cluster Management may expose cluster tokens

CVE-2026-70398 · published 2 months ago
Summary

In Red Hat Advanced Cluster Management, an authenticated tenant can trick the GitOpsCluster controller into moving bearer tokens that grant access to managed clusters into a namespace they control. This could let the tenant view or use those tokens, bypassing normal security rules. Apply the latest updates from Red Hat and review tenant permissions to prevent this behavior.

Original advisory text
Multicloud-integrations: multicloud-integrations: gitopscluster.spec.argoserver.argonamespace writes spoke bearer tokens to attacker-chosen namespace
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.
