CVE-2026-73137
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se encontró una falla en el componente multicloud-operators-subscription de Red Hat Advanced Cluster Management (RHACM). Un inquilino con permisos de creación de HelmRelease puede explotar esta vulnerabilidad manipulando el campo ’secretRef.Namespace’. Esto permite que la función ’GetSecret()’ en el controlador de HelmRelease recupere credenciales sensibles de cualquier espacio de nombres, las cuales luego se envían a un repositorio Helm controlado por el atacante. Esto puede conducir a la exfiltración de credenciales de Secrets de espacios de nombres arbitrarios, lo que resulta en revelación de información."
