{"cve":"CVE-2026-7374","nvd":{"published":"2026-05-26T14:16:40.717","modified":"2026-09-10T13:20:31.720","status":"Awaiting Analysis","description":"A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-59"],"references":["https://access.redhat.com/errata/RHSA-2026:20720","https://access.redhat.com/errata/RHSA-2026:20736","https://access.redhat.com/errata/RHSA-2026:20763","https://access.redhat.com/errata/RHSA-2026:20767","https://access.redhat.com/errata/RHSA-2026:20782"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-7374","score":0.00742,"percentile":0.54697,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7jcp-v9w4-wjmg","url":"https://osv.dev/vulnerability/GHSA-7jcp-v9w4-wjmg","summary":"KubeVirt has a Link Following vulnerability","modified":"2026-09-10T03:50:46.239164927Z","packages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":[">=1.8.0-alpha.0 <1.8.3"],"fixed":["1.8.3"]},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":[">=1.7.0-alpha.0 <1.7.4"],"fixed":["1.7.4"]},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":["<1.6.6"],"fixed":["1.6.6"]}]},{"id":"GO-2026-5848","url":"https://osv.dev/vulnerability/GO-2026-5848","summary":"KubeVirt has a Link Following vulnerability in kubevirt.io/kubevirt","modified":"2026-07-07T16:01:34.756255829Z","packages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","purl":"pkg:golang/kubevirt.io/kubevirt","ranges":["<1.6.6",">=1.7.0-alpha.0 <1.7.4",">=1.8.0-alpha.0 <1.8.3"],"fixed":["1.6.6","1.7.4","1.8.3"]}]}],"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).
