There is no available exploit. It is recommended to upgrade the affected component. Detailsinfo A vulnerability classified as critical was found in kata-containers Kata Containers up to 3.28.x. Affected by this vulnerability is some unknown processing of the component CopyFile Handler. The manipulation with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is: Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. From v3.4.0 to v3.28.0, an oversight in the CopyFile policy (and perhaps the CopyFile handler) allows untrusted hosts to write to arbitrary locations inside the guest workload image. This can be used to overwrite binaries inside the guest and exfiltrate data from containers; even those running inside CVMs. This vulnerability is fixed in v3.29.0. The advisory is shared at github.com. This vulnerability is known as CVE-2026-41326 since 04/20/2026. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. Upgrading to version 3.29.0 eliminates this vulnerability.
