CVE-2026-73137 is a vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11 affecting the multicloud-operators-subscription component. A tenant with HelmRelease create permissions can manipulate the secretRef.Namespace field to cause the HelmRelease controller's GetSecret() function to retrieve sensitive credentials from any namespace. These credentials are then sent to an attacker-controlled Helm repository, leading to information disclosure. The vulnerability has a CVSS 3.1 base score of 7.7 (high severity).

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.
