Last modified
CVE-2019-11255 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 1.75% chance of exploitation in the next 30 days.
