Authentication Bypass in OpenChoreo Kubernetes Platform

Publication date: 2026-08-13

Last updated on: 2026-08-13

Assigner: GitHub, Inc.

Description

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.

Attack-Flow Graph

Executive Summary

OpenChoreo is a developer platform for Kubernetes. Prior to versions 1.0.2 and 1.1.2, it had a flaw where internal management APIs were exposed on an externally reachable listener without authentication. This allowed attackers to access /api/proxy/ and /api/exec/ endpoints, proxy the Kubernetes API, and execute commands in workload pods across clusters.

Detection Guidance

Check if your OpenChoreo deployment is running versions prior to 1.0.2 or 1.1.2. Inspect network traffic for unauthorized access to /api/proxy/ or /api/exec/ endpoints. Verify if internal management APIs are exposed externally without authentication.

Impact Analysis

Attackers could gain unauthorized access to your Kubernetes clusters, steal sensitive data, manipulate workloads, or execute arbitrary commands in your pods. This could lead to data breaches, service disruption, or full cluster compromise, especially in multi-cluster deployments.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or health data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations may face fines, legal penalties, and reputational damage due to non-compliance.

Mitigation Strategies

Upgrade OpenChoreo to version 1.0.2 or 1.1.2 or later immediately. Ensure management APIs are not exposed externally without authentication. Restrict network access to internal listeners if possible.
