The gateway exposed internal management endpoints, including arbitrary Kubernetes proxying and execution interfaces, on an unauthenticated port. An adjacent attacker within the control-plane network can bypass RBAC controls entirely and gain administrative control over all connected data planes.\n\n## TL;DR\nOpenChoreo cluster-gateway exposed administrative routes on port 8444 without requiring authentication, enabling network-adjacent attackers to execute arbitrary commands and retrieve secrets across connected Kubernetes clusters.\n\n## Technical Details\n\n- **CWE ID**: CWE-306\n- **Attack Vector**: Adjacent\n- **CVSS v3.1 Score**: 9.0\n- **EPSS Score**: 0.0018 (0.18%)\n- **Exploit Status**: none\n- **CISA KEV**: No\n\n## Affected Systems\n\n- OpenChoreo cluster-gateway control-plane component\n- **OpenChoreo**: < 1.0.3 (Fixed in: `1.0.3`)\n- **OpenChoreo**: >= 1.1.0, < 1.1.3 (Fixed in: `1.1.3`)\n- **OpenChoreo**: >= 1.2.0-rc.1, < 1.2.0-rc.2 (Fixed in: `1.2.0-rc.2`)\n\n## Mitigation\n\n- Enforce Mutual TLS (mTLS) on port 8444 with a cryptographically isolated Certificate Authority.\n- Deploy Kubernetes NetworkPolicies to restrict ingress on port 8444 to authorized control-plane components only.\n- Implement continuous log auditing to scan for unauthenticated requests directed at internal /api/ endpoints.\n\n**Remediation Steps:**\n1. Upgrade OpenChoreo deployment to version 1.0.3, 1.1.3, or 1.2.0-rc.2.\n2. Verify that the Helm parameter clusterGateway.internalMtls.enabled is explicitly set to true.\n3. Deploy network isolation policy to restrict adjacent network communications targeting the gateway pod.\n\n## References\n\n- [GitHub Security Advisory GHSA-rh53-xvx2-j327](https://github.com/openchoreo/openchoreo/security/advisories/GHSA-rh53-xvx2-j327)\n- [OpenChoreo Pull Request 4256](https://github.com/openchoreo/openchoreo/pull/4256)\n- [OpenChoreo Pull Request 4258](https://github.com/openchoreo/openchoreo/pull/4258)\n- [OpenChoreo Pull Request 4259](https://github.com/openchoreo/openchoreo/pull/4259)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-73842) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-05T00:01:05.845549Z"} 2026-09-05T00:01:05.845549+00:00 https://vulnerability.circl.lu/sighting/798f04a1-82cc-4d79-bc83-26c9b2376b26/export 2026-09-13T15:10:11.027025+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "798f04a1-82cc-4d79-bc83-26c9b2376b26", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "GHSA-rh53-xvx2-j327", "type": "seen", "source": "https://gist.github.com/alon710/e3fcd961ce3e45afd531f9a1d48bb4cf", "content": "# CVE-2026-73842: CVE-2026-73842: Missing Authentication and Authorization on Internal Management Listener in OpenChoreo cluster-gateway\n\n> **CVSS Score:** 9.0\n> **Published:** 2026-09-04\n> **Full Report:** https://cvereports.com/reports/CVE-2026-73842\n\n## Summary\nA critical-severity missing authentication and privilege management vulnerability was identified in the OpenChoreo cluster-gateway component.
