CVE-2025-59358
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
