Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26484 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kubevirt.io/kubevirt (Go): affected all versions up to 0.59.0; no fix listed\n- kubevirt.io/kubevirt (Go): affected all versions up to 0.59.0; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-26484/ (Markdown: https://insights.sbomify.com/CVE-2023-26484/index.md)","id":"CVE-2023-26484","markdown":"https://insights.sbomify.com/CVE-2023-26484/index.md","name":"CVE-2023-26484","record":{"aliases":["AZL-25673","AZL-34902","GHSA-cp96-jpmq-xrr2","SUSE-SU-2023:1967-1","openSUSE-SU-2024:12792-1"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"workaround","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"KubeVirt virtualization","requires_auth":"low_privilege","summary":"A compromised KubeVirt node allows attackers to modify node specs via the virt-handler service account, escalating privileges to access cluster secrets and other nodes.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kubevirt","vendor":"kubevirt"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"KubeVirt is a virtual machine management add-on for Kubernetes. In versions 0.59.0 and prior, if a malicious user has taken over a Kubernetes node where virt-handler (the KubeVirt node-daemon) is running, the virt-handler service account can be used to modify all node specs. This can be misused to lure-in system-level-privileged components which can, for instance, read all secrets on the cluster, or can exec into pods on other nodes. This way, a compromised node can be used to elevate privileges beyond the node until potentially having full privileged access to the whole cluster. The simplest way to exploit this, once a user could compromise a specific node, is to set with the virt-handler service account all other nodes to unschedulable and simply wait until system-critical components with high privileges appear on its node. No patches are available as of time of publication. As a workaround, gatekeeper users can add a webhook which will block the `virt-handler` service account to modify the spec of a node.","ecosystems":["Go","SUSE:Linux Enterprise Micro 5.3","SUSE:Linux Enterprise Micro 5.4","SUSE:Linux Enterprise Module for Containers 15 SP4","openSUSE:Leap 15.4","openSUSE:Leap Micro 5.3","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"On a compromised KubeVirt node, the virt-handler service account can be used to modify all node specs","id":"CVE-2023-26484","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"privilege_escalation","year":"2023"},"n_packages":8,"n_references":2,"next":{"headline":"Quadratic complexity may lead to a denial of service in cmark-gfm","id":"CVE-2023-26485"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.59.0"],"package":"kubevirt.io/kubevirt","purl":null,"source":"GHSA-cp96-jpmq-xrr2"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.59.0"],"package":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","source":"GHSA-cp96-jpmq-xrr2"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.3","fixed":["0.54.0-150400.3.13.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/suse/kubevirt\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.3","source":"SUSE-SU-2023:1967-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.4","fixed":["0.54.0-150400.3.13.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/suse/kubevirt\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.4","source":"SUSE-SU-2023:1967-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Containers 15 SP4","fixed":["0.54.0-150400.3.13.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/suse/kubevirt\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Containers%2015%20SP4","source":"SUSE-SU-2023:1967-1"},{"ecosystem":"openSUSE:Leap 15.4","fixed":["0.54.0-150400.3.13.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/opensuse/kubevirt\u0026distro=openSUSE%20Leap%2015.4","source":"SUSE-SU-2023:1967-1"},{"ecosystem":"openSUSE:Leap Micro 5.3","fixed":["0.54.0-150400.3.13.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/opensuse/kubevirt\u0026distro=openSUSE%20Leap%20Micro%205.3","source":"SUSE-SU-2023:1967-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.59.0-2.1"],"introduced":["0"],"last_affected":[],"package":"kubevirt","purl":"pkg:rpm/opensuse/kubevirt\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:12792-1"}],"prev":{"headline":"gosaml2 vulnerable to Denial of Service via deflate decompression bomb","id":"CVE-2023-26483"},"products":["kubevirt"],"published":"2023-03-15","related":[{"cvss_score":9.9,"headline":"Privilege Escalation in kubevirt","id":"CVE-2020-14316","kev_date_added":null,"published":"2020-07-29"},{"cvss_score":8.7,"headline":"Path Traversal vulnerability in Kubevirt","id":"CVE-2022-1798","kev_date_added":null,"published":"2022-09-15"},{"cvss_score":8.5,"headline":"KubeVirt Vulnerable to Arbitrary Host File Read and Write","id":"CVE-2025-64324","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":7.3,"headline":"Path traversal in Red Hat Container Native Virtualization 4.12","id":"CVE-2026-13201","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":6.9,"headline":"KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes","id":"CVE-2025-64436","kev_date_added":null,"published":"2025-11-07"},{"cvss_score":6.5,"headline":"Auth bypass in Red Hat OpenShift Virtualization 4","id":"CVE-2026-13208","kev_date_added":null,"published":"2026-06-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-25","vendors":["kubevirt"]},"summary":"A compromised KubeVirt node allows attackers to modify node specs via the virt-handler service account, escalating privileges to access cluster secrets and other nodes.","url":"https://insights.sbomify.com/CVE-2023-26484/"}
