{"cve":"CVE-2025-64324","nvd":{"published":"2025-11-18T23:15:55.293","modified":"2026-10-19T13:10:00.110","status":"Analyzed","description":"KubeVirt is a virtual machine management add-on for Kubernetes. The `hostDisk` feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, prior to version 1.6.1 and 1.7.0, the implementation of this feature and more specifically the `DiskOrCreate` option (which creates a file if it doesn't exist) has a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users on the host system. Versions 1.6.1 and 1.7.0 fix the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.7},"cwes":["CWE-200","CWE-732"],"references":["https://github.com/kubevirt/kubevirt/commit/00d03e43e3bf03e563136695a4732b65ed42d764","https://github.com/kubevirt/kubevirt/commit/ff3b69b08b6b9c8d08d23735ca8d82455f790a69","https://github.com/kubevirt/kubevirt/pull/15037","https://github.com/kubevirt/kubevirt/security/advisories/GHSA-46xp-26xh-hpqh"],"products":["kubevirt:kubevirt"],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-64324","score":0.00239,"percentile":0.14867,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-46xp-26xh-hpqh","url":"https://osv.dev/vulnerability/GHSA-46xp-26xh-hpqh","summary":"KubeVirt Vulnerable to Arbitrary Host File Read and Write","modified":"2026-09-10T03:50:30.423983182Z","packages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":["<1.6.1"],"fixed":["1.6.1"]},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":[">=1.7.0-alpha.0 <1.7.0-rc.0"],"fixed":["1.7.0-rc.0"]}]},{"id":"GO-2025-4110","url":"https://osv.dev/vulnerability/GO-2025-4110","summary":"KubeVirt Vulnerable to Arbitrary Host File Read and Write in kubevirt.io/kubevirt","modified":"2026-03-25T20:40:12.748914Z","packages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":["<1.6.1",">=1.6.2 <1.7.0-rc.0"],"fixed":["1.6.1","1.7.0-rc.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
