CVE-2026-73842

Data-plane takeover via unauthenticated gateway APIs

Published Aug 13, 2026 · Updated Aug 13, 2026

Authentication bypass in OpenChoreo before 1.0.3, 1.1.0 through 1.1.2, and 1.2.0-rc.1 allows remote attackers to access data planes. The internal/cluster-gateway/server.go listener routes /api/proxy/, /api/exec/, and /api/wirelogs/ without verifying a client certificate or token and permits Secret reads and mutating Kubernetes methods. Access requires network reachability to the internal listener; exploitation exposes tenant Secrets and permits workload creation, modification, deletion, and pod command execution across connected data planes.
