Descriptions

Improper input validation in Kubernetes CSI sidecar containers for external-provisioner (<v0.4.3, <v1.0.2, v1.1, <v1.2.2, <v1.3.1), external-snapshotter (<v0.4.2, <v1.0.2, v1.1, <1.2.2), and external-resizer (v0.1, v0.2) could result in unauthorized PersistentVolume data access or volume mutation during snapshot, restore from snapshot, cloning and resizing operations.

Una comprobación de entrada inapropiada en contenedores sidecar de Kubernetes CSI para external-provisioner (versiones anteriores a v0.4.3, versiones anteriores a v1.0.2, v1.1, versiones anteriores a v1.2.2, versiones anteriores a v1.3.1), external-snapshotter (versiones anteriores a v0.4.2, versiones anteriores a v1. 0.2, v1.1, versiones anteriores a 1.2.2) y external-resizer (versiones v0.1, v0.2), podrían resultar en el acceso no autorizado a los datos PersistentVolume o la mutación del volumen durante una imagen instantánea, una restauración desde una imagen instantánea, la clonación y el cambio de tamaño.
