{"id":"CVE-2025-64436","state":"PUBLISHED","title":"KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes","description":"KubeVirt is a virtual machine management add-on for Kubernetes. 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.","publishedAt":"2025-11-07T22:59:47.228Z","updatedAt":"2025-11-10T18:53:09.436Z","severity":{"score":6.9,"label":"Medium","version":"4.0","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","source":"GitHub_M"},"assigner":"GitHub_M","products":["kubevirt kubevirt"],"affected":[{"vendor":"kubevirt","product":"kubevirt","versions":[{"version":"<= 1.5.0","status":"affected"}]}],"references":["https://github.com/kubevirt/kubevirt/security/advisories/GHSA-7xgm-5prm-v5gc"],"weaknesses":["CWE-269","CWE-276"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/64xxx/CVE-2025-64436.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-64436","state":"PUBLISHED","datePublished":"2025-11-07T22:59:47.228Z","dateUpdated":"2025-11-10T18:53:09.436Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-11-03T22:12:51.365Z"},"containers":{"cna":{"title":"KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes","descriptions":[{"lang":"en","value":"KubeVirt is a virtual machine management add-on for Kubernetes.
