CVE-2026-9804

Kubevirt: kubevirt: vmexport directory symlink escape enables exporter pod file read

Published May 28, 2026 CVSS 3.1 · 7.7 High EPSS < 1% KEV · Not listed
Description
A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root, the attacker can read arbitrary files from the exporter pod's filesystem. This leads to information disclosure, potentially exposing sensitive data.
