Vulnerability Title
Improper KubeConfig handling allows arbitrary code execution
Source: CVE Program / CVE List V5
Vulnerability Description
The GitOps Tools Extension for VSCode relies on kubeconfigs in order to communicate with Kubernetes clusters. A specially crafted kubeconfig leads to arbitrary code execution on behalf of the user running VSCode. Users relying on kubeconfigs that are generated or altered by other processes or users are affected by this issue. Please note that the vulnerability is specific to this extension, and the same kubeconfig would not result in arbitrary code execution when used with kubectl. Using only trust-worthy kubeconfigs is a safe mitigation. However, updating to the latest version of the extension is still highly recommended.
