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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2804-1 advisory.

    - CVE-2026-9804: Symlink escape in the VMExport dir       handler let an attacker controlling an exported PVC read sensitive       files (TLS keys, tokens, service-account creds) from the exporter       pod. (bsc#1266733)
    - CVE-2025-14525: A VM reporting many guest-internal       interfaces via the guest agent could flood VMI status and fill etcd       (denial of service). Caps reported interfaces at 10. (bsc#1256434)
    - CVE-2026-35469: resource-exhaustion       in the SPDY/3 protocol implementation of       github.com/moby/spdystream. (GHSA-pc3f-x583-g7j2,bsc#1262265)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
