CVE-2026-73843
SUMMARY

OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.2 and 1.1.2, internal/cluster-gateway/server.go served caller-facing management APIs on the externally reachable agent listener without authentication, allowing network-reachable attackers to invoke /api/proxy/ and /api/exec/ operations, proxy the data-plane Kubernetes API, and execute commands in workload pods in multi-cluster deployments. This issue is fixed in versions 1.0.2 and 1.1.2.

CVE-2026-73842
SUMMARY

OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.3, 1.1.3, and 1.2.0-rc.2, internal/cluster-gateway/server.go exposed /api/proxy/, /api/exec/, and /api/wirelogs/ on an internal listener without requiring a client certificate or token, allowing any network-reachable caller to read tenant Kubernetes Secrets, mutate workloads, and execute commands across connected data planes. This issue is fixed in versions 1.0.3, 1.1.3, and 1.2.0-rc.2.

CVE-2026-73841
SUMMARY

OpenChoreo is a complete, open-source developer platform for Kubernetes. From 1.2.0-rc.1 until 1.2.0, internal/openchoreo-api/api/handlers/exec.go and internal/openchoreo-api/api/handlers/wirelogs.go authorize component:exec and wirelogs:view using the caller-supplied project query parameter instead of comp.Spec.Owner.ProjectName, allowing a user with a project-scoped grant to execute commands in and read wirelogs from components owned by other projects in the same namespace. This vulnerability is fixed in 1.2.0.
