CVE-2025-59358: Chaos Mesh's Chaos Controller Manager is Missing Authentication for Critical Function

The Chaos Controller Manager in Chaos Mesh exposes a GraphQL debugging server without authentication to the entire Kubernetes cluster, which provides an API to kill arbitrary processes in any Kubernetes pod, leading to cluster-wide denial of service.

Root Cause Analysis

The vulnerability lies in the Chaos Controller Manager of Chaos Mesh, which exposes a GraphQL server for debugging purposes without authentication. This server provides an API to kill arbitrary processes in any pod within the Kubernetes cluster, leading to a potential denial of service. The analysis of the provided information, including the commit that patches the vulnerability, reveals that the main.Run function in cmd/chaos-controller-manager/main.go is responsible for starting this server. The patch mitigates the vulnerability by disabling the server by default through a configuration change in the Helm chart (enableCtrlServer: false). The vulnerable function is main.Run because it contains the logic that initiates the unauthenticated server. An attacker could exploit this by sending a crafted GraphQL request to the exposed endpoint to terminate critical processes, disrupting the entire cluster.
