CVE-2019-10175 — Kubevirt Containerized-Data-Importer security vulnerability

Medium CVSS 6.5

A flaw was found in the containerized-data-importer in virt-cdi-cloner, version 1.4, where the host-assisted cloning feature does not determine whether the requesting user has permission to access the Persistent Volume Claim (PVC) in the source namespace. This could allow users to clone any PVC in the cluster into their own namespace, effectively allowing access to other user's data.

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
