| CVE-2020-14316 | Cri | 0.64 | 9.9 | 0.02 | Jul 29, 2020 | A flaw was found in kubevirt 0.29 and earlier. Virtual Machine Instances (VMIs) can be used to gain access to the host's filesystem. Successful exploitation allows an attacker to assume the privileges of the VM process on the host system. In worst-case scenarios an attacker can… | ||
| CVE-2026-7374 | Cri | 0.57 | 9.9 | 0.01 | May 26, 2026 | 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… | ||
| CVE-2022-1798 | Hig | 0.57 | 8.7 | 0.00 | Sep 15, 2022 | A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable or which are readable for UID 107 or GID 107. /proc/self/<> is not… | ||
| CVE-2023-26484 | Hig | 0.53 | 8.2 | 0.01 | Mar 15, 2023 | 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.… | ||
| CVE-2019-3841 | Hig | 0.48 | 7.4 | 0.01 | Mar 25, 2019 | Kubevirt/virt-cdi-importer, versions 1.4.0 to 1.5.3 inclusive, were reported to disable TLS certificate validation when importing data into PVCs from container registries. This could enable man-in-the-middle attacks between a container registry and the virt-cdi-component,… | ||
| CVE-2026-13201 | Hig | 0.47 | 7.3 | 0.00 | Jun 24, 2026 | A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses O_PATH|O_NOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a… | ||
| CVE-2026-9804 | Hig | 0.43 | 7.7 | 0.01 | May 28, 2026 | A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim… | ||
| CVE-2025-64324 | Hig | 0.43 | 7.7 | 0.00 | Nov 18, 2025 | 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… | ||
| CVE-2026-102623 | Med | 0.42 | 6.5 | — | Sep 29, 2026 | A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate… | ||
| CVE-2026-13318 | Med | 0.42 | 6.4 | 0.00 | Jun 26, 2026 | A server-side request forgery (SSRF) flaw was found in KubeVirt's virt-api port-forward handler. When processing a port-forward request to a VirtualMachineInstance (VMI), virt-api reads the target IP from vmi.Status.Interfaces[0].IP and passes it directly to net.Dial() without… | ||
| CVE-2026-13208 | Med | 0.42 | 6.5 | 0.00 | Jun 24, 2026 | A flaw was found in KubeVirt's virt-handler domain notify server. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI identity (namespace/name) solely from the request body without validating it against the connection's origin. Each virt-launcher pod… | ||
| CVE-2024-33394 | Med | 0.38 | 5.9 | 0.00 | May 2, 2024 | An issue in kubevirt kubevirt v1.2.0 and before allows a local attacker to execute arbitrary code via a crafted command to get the token component. | ||
| CVE-2025-64433 | Med | 0.35 | 6.5 | 0.00 | Nov 7, 2025 | KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, a vulnerability was discovered that allows a VM to read arbitrary files from the virt-launcher pod's file system. This issue stems from improper symlink handling when mounting PVC disks… | ||
| CVE-2020-1701 | Med | 0.35 | 6.5 | 0.01 | May 27, 2021 | A flaw was found in the KubeVirt main virt-handler versions before 0.26.0 regarding the access permissions of virt-handler. An attacker with access to create VMs could attach any secret within their namespace, allowing them to read the contents of that secret. | ||
| CVE-2025-64436 | Med | 0.34 | 5.3 | 0.00 | Nov 7, 2025 | 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… | ||
| CVE-2026-13434 | Med | 0.32 | 4.9 | 0.00 | Jun 26, 2026 | A flaw was found in KubeVirt's network annotation generator. When a tenant creates a VirtualMachineInstance with a Multus network configuration, the supplied networkName value is written verbatim into the launcher pod's v1.multus-cni.io/default-network annotation without format… | ||
| CVE-2026-13218 | Med | 0.27 | 4.2 | 0.00 | Jun 26, 2026 | A flaw was found in KubeVirt's virt-handler network cache handling. The WriteToCachedFile function writes data to a launcher-rooted path using os.WriteFile and os.Chown without symlink protection. A user with access to the virt-launcher container can plant a symlink at the cache… | ||
| CVE-2025-64435 | Med | 0.27 | 5.3 | 0.00 | Nov 7, 2025 | KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.7.0-beta.0, a logic flaw in the virt-controller allows an attacker to disrupt the control over a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod associated with the… | ||
| CVE-2025-64437 | Med | 0.26 | 5.0 | 0.00 | Nov 7, 2025 | KubeVirt is a virtual machine management add-on for Kubernetes. In versions before 1.5.3 and 1.6.1, the virt-handler does not verify whether the launcher-sock is a symlink or a regular file. This oversight can be exploited, for example, to change the ownership of arbitrary files… | ||
| CVE-2026-13322 | Low | 0.25 | 3.8 | 0.00 | Jun 26, 2026 | A flaw was found in KubeVirt's downward metrics virtio-serial server.
