In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-269","CWE-276"],"references":["https://github.com/kubevirt/kubevirt/security/advisories/GHSA-7xgm-5prm-v5gc"],"products":["kubevirt:kubevirt"],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-64436","score":0.00279,"percentile":0.20382,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7xgm-5prm-v5gc","url":"https://osv.dev/vulnerability/GHSA-7xgm-5prm-v5gc","summary":"KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes","modified":"2026-09-10T03:50:30.685229168Z","packages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":["<1.7.0"],"fixed":["1.7.0"]}]},{"id":"GO-2025-4104","url":"https://osv.dev/vulnerability/GO-2025-4104","summary":"KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes in github.com/kubevirt/kubevirt","modified":"2026-06-20T00:59:19.010406356Z","packages":[{"ecosystem":"Go","name":"github.com/kubevirt/kubevirt","purl":"pkg:golang/github.com/kubevirt/kubevirt","ranges":["all versions"],"fixed":[]}]}],"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).
