CVSS 3.1
9.6 criticalCVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:HCVE-2026-73843
Critical (9.6). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/openchoreo/openchoreo 1.0.2, 1.1.2.
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.
