6.5 mediumCVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:NCVE-2019-11255
Medium (6.5). EPSS 2.0% chance of exploitation in the next 30 days. Fixed in github.com/kubernetes-csi/external-provisioner 0.4.3, 1.0.2, 1.2.2.
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.
