CVE-2026-72508 (GCVE-0-2026-72508)

Vulnerability from cvelistv5 – Published: 2026-08-12 19:41 – Updated: 2026-09-05 14:24

Title

Multicloud-operators-subscription: multicloud-operators-subscription: hub and spoke serviceaccounts bound to wildcard rbac (*/*/*)

Summary

A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows a namespace-admin tenant to perform a confused-deputy attack by creating Subscription Custom Resources (CRs) that leverage a highly privileged ServiceAccount (SA). This enables the tenant to deploy arbitrary cluster-scoped resources, leading to privilege escalation and potential arbitrary code execution across the cluster.

This vulnerability allows a namespace-admin tenant to perform a confused-deputy attack by creating Subscription Custom Resources (CRs) that leverage a highly privileged ServiceAccount (SA). This enables the tenant to deploy arbitrary cluster-scoped resources, leading to privilege escalation and potential arbitrary code execution across the cluster.",
