CVE-2026-19130
Full vulnerability record from the local CVENow database.
Description
A flaw was found in the provider-credential-controller component of multicluster-engine (MCE). An attacker with specific permissions on the hub cluster, and knowledge of a prior credential value, could exploit an authorization bypass vulnerability. By manipulating `copiedFrom` labels, the attacker could intercept newly rotated provider credentials, leading to unauthorized information disclosure. This allows access to sensitive credentials that should otherwise be protected.

"value": "Se encontró una falla en el componente provider-credential-controller de multicluster-engine (MCE). Un atacante con permisos específicos en el clúster central, y conocimiento de un valor de credencial anterior, podría explotar una vulnerabilidad de omisión de autorización. Al manipular las etiquetas ’copiedFrom’, el atacante podría interceptar credenciales de proveedor recién rotadas, lo que lleva a una revelación de información no autorizada. Esto permite el acceso a credenciales sensibles que de otro modo deberían estar protegidas."
