Vulnerability Title
OpenChoreo: cluster-gateway internal proxy performs no caller authentication and is not read-only — data-plane Secret disclosure and arbitrary Kubernetes mutation
Source: CVE Program / CVE List V5
Vulnerability Description
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.
