High [CVE-2026-73137] cross-namespace Secret exfiltration via HelmRelease.repo.secretRef.namespace
CVE-2026-73137Source published Source updated
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. This allows for unauthorized access to sensitive data across the cluster. Red Hat severity: Important — CVSS 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N). Weakness: CWE-200. Affected Red Hat products: Red Hat Advanced Cluster Management for…
