Red Hat
Parameter Value
CVSS 7.7 (HIGH)
Type CWE-200 (Information Exposure)
Vendor Red Hat
Public PoC No

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.
