RHACM multicloud-integrations Authenticated Token Disclosure via GitOpsCluster
CVE-2026-70398 Published on August 12, 2026
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.

Weakness Type
What is a Confused Deputy Vulnerability?
The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.
CVE-2026-70398 has been classified to as a Confused Deputy vulnerability or weakness.
