RHACM multicloud-operators-subscription: privilege escalation allows exfil
CVE-2026-73137 Published on August 20, 2026
Multicloud-operators-subscription: multicloud-operators-subscription: cross-namespace secret exfiltration via helmrelease.repo.secretref.namespace
A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). A tenant with HelmRelease create permissions can exploit this vulnerability by manipulating the `secretRef.Namespace` field. This allows the `GetSecret()` function in the HelmRelease controller to fetch sensitive credentials from any namespace, which are then sent to an attacker-controlled Helm repository. This can lead to the exfiltration of credentials from arbitrary namespace Secrets, resulting in information disclosure.
