Summary

KubeVela before versions 1.9.14, 1.10.9, and 1.11.0-alpha.4 has a vulnerability in the Terraform remote configuration loader. A user with permission to create or update ComponentDefinition can point terraform.path to /dev/zero, causing an unbounded read and memory exhaustion.

Risk Assessment

An attacker can cause memory exhaustion, kill the vela-core controller, and cause repeated Pod restarts, leading to platform unavailability.

Recommendation

Update KubeVela to version 1.9.14, 1.10.9, or 1.11.0-alpha.4 which contain the fixes.

Original NVD description (English source)

KubeVela is an open source application delivery platform. Prior to 1.9.14, from 1.10.0-alpha.1 until 1.10.9, and from 1.11.0-alpha.1 until 1.11.0-alpha.4, the Terraform remote configuration loader in pkg/controller/utils/capability.go, GetTerraformConfigurationFromRemote, clones a repository supplied through a core.oam.dev/v1beta1 ComponentDefinition and follows repository-controlled variables.tf or main.tf symlinks. A user with permission to create or update ComponentDefinition objects can point variables.tf to /dev/zero through terraform.path, after which os.Stat and os.ReadFile follow the link and read an unbounded stream before ParseTerraformVariables or HCL parsing can reject the content. The read can exhaust memory, OOM-kill the cluster-wide vela-core controller, cause repeated Pod restarts, and pressure node memory when no effective container limit is configured. This issue is fixed in versions 1.9.14, 1.10.9, and 1.11.0-alpha.4.
