{"id":"AZL-91457","summary":"CVE-2026-13318 affecting package kubevirt 1.7.1-8","details":"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 validation. For VMIs using non-masquerade network bindings (bridge or secondary-only), this IP is reported by the QEMU guest agent running inside the VM and is fully controllable by the VM owner. An attacker with kubevirt.io:edit permissions can create a VM with a modified guest agent that reports an arbitrary IP address, then request port-forward to establish a bidirectional TCP tunnel from virt-api's cluster-internal network position to any routable destination, bypassing NetworkPolicy isolation.","modified":"2026-08-30T05:26:50Z","published":"2026-06-26T00:16:51Z","upstream":["CVE-2026-13318"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13318"}],"affected":[{"package":{"name":"kubevirt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kubevirt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.7.1-8"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91457.json"}}],"schema_version":"1.9.0"}
