{"id":"AZL-91463","summary":"CVE-2026-13218 affecting package kubevirt 1.7.1-8","details":"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 file path, causing virt-handler to follow it and overwrite an arbitrary host file with JSON content and change its ownership.","modified":"2026-08-30T05:26:50Z","published":"2026-06-26T00:16:51Z","upstream":["CVE-2026-13218"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13218"}],"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-91463.json"}}],"schema_version":"1.9.0"}
