Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenChoreo versions before 1.0.2 and from 1.1.0 before 1.1.2 are vulnerable. In multi-cluster deployments, the cluster-gateway's management APIs shared a publicly reachable listener with data-plane agent connections and did not authenticate callers. An attacker who can reach that endpoint could run privileged data-plane operations, such as proxying the Kubernetes API and executing commands in workload pods, without passing OpenChoreo's authorization. Upgrade to 1.0.2, 1.1.2, or 1.2.0. If you cannot upgrade, restrict access to the external gateway endpoint to known data-plane addresses.
