CVE-2026-13218

CVE-2026-13218 : In KubeVirt, the virt-handler network cache handling allows a symlink attack via WriteToCachedFile, which writes to a launcher-rooted path with os.WriteFile and os.Chown. A user inside the virt-launcher container can place a symlink at the cache path, causing virt-handler to foll...

CVE-2026-13218

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, causin...

CVE-2026-13208

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 connects through a per-VMI...

CVE-2026-13201

A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses OPATH|ONOFOLLOW 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 symlink, the kernel...

CVE-2026-13208

CVE-2026-13208 describes a flaw in KubeVirt where virt-handler’s domain notify server trusts VMI identity from the unvalidated request body. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI (namespace/name) solely from the request payload, with no identity validation agai...
