| CVE-2026-13622 | Hig | 0.57 | 8.8 | 0.00 | Aug 12, 2026 | A symlink following vulnerability was found in KubeVirt's virt-handler migration proxy. During live migration, virt-handler dials Unix sockets inside the target virt-launcher pod via /proc//root/ paths using net.Dial() without symlink protection. These socket paths reside… | ||
| 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.

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-2026-13318 | 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. The server reads guest requests using textproto.Reader.ReadLine(), which buffers input indefinitely until a newline character is received, with no length limit or read deadline. A user with access to a VM… | ||
| CVE-2025-64434 | Med | 0.24 | 4.7 | 0.00 | Nov 7, 2025 | KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, due to the peer verification logic in virt-handler (via verifyPeerCert), an attacker who compromises a virt-handler instance, could exploit these shared credentials to impersonate virt-api… |
