The flaw occurs due to server-side string interpolation of workflow parameters into inline shell scripts and insecure shell parameter expansion. This allows low-privileged attackers to execute arbitrary shell commands inside privileged containers, leading to potential host privilege escalation.\n\n## TL;DR\nAuthenticated OS command injection in OpenChoreo workflow templates allows execution of arbitrary commands with container root privileges.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-78\n- **Attack Vector**: Network (AV:N)\n- **CVSS Base Score**: 8.8\n- **Privileges Required**: Low (PR:L)\n- **Exploit Status**: Proof of Concept (PoC)\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- OpenChoreo Workflow Plane\n- OpenChoreo Argo Workflows Integration\n- **OpenChoreo**: < 1.0.4 (Fixed in: `1.0.4`)\n- **OpenChoreo**: >= 1.1.0, < 1.1.4 (Fixed in: `1.1.4`)\n- **OpenChoreo**: >= 1.2.0-rc.1, < 1.2.0-rc.2 (Fixed in: `1.2.0-rc.2`)\n\n## Mitigation\n\n- Map workflow parameters to container environment variables instead of using raw string interpolation in inline shell scripts.\n- Utilize double-quoted variable expansion inside shell scripts to prevent token splitting and injection.\n- Enforce host-user namespace isolation ('hostUsers: false') for privileged workflow pods.\n- Employ base64-encoding to safely pass complex parameter vectors to inner loop parsing structures.\n\n**Remediation Steps:**\n1. Upgrade OpenChoreo deployments to version 1.0.4, 1.1.4, 1.2.0-rc.2, or higher.\n2. Audit custom workflow templates in use to ensure no legacy server-side interpolation placeholders exist inside inline command scripts.\n3. Enable Kubernetes Pod Security Standards or Gatekeeper policies to enforce 'hostUsers: false' on privileged workloads.\n\n## References\n\n- [GHSA-2mw5-23gm-pccq Advisory](https://github.com/openchoreo/openchoreo/security/advisories/GHSA-2mw5-23gm-pccq)\n- [NVD - CVE-2026-73667](https://nvd.nist.gov/vuln/detail/CVE-2026-73667)\n- [CVE.org Record](https://www.cve.org/CVERecord?id=CVE-2026-73667)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-73667) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-03T00:32:06.611331Z"} 2026-09-03T00:32:06.611331+00:00 https://vulnerability.circl.lu/sighting/9045f4a8-cb6b-4eb0-ab2d-a3550ce82cf8/export 2026-09-15T18:45:28.621415+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "9045f4a8-cb6b-4eb0-ab2d-a3550ce82cf8", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-73667", "type": "seen", "source": "https://bsky.app/profile/termsofsurrender.bsky.social/post/3msywtior6n25", "content": "OpenChoreo Bleeds Out While Everyone Pretends This Was a Strategy\nPANIC 78% | Lag 0.0h | CVE-2026-73667 is a high-severity vulnerability in OpenChoreo, a Kubernetes developer platform, affe\n#AfterShockIndex\nREAD MORE", "creation_timestamp": "2026-08-14T00:49:55.259417Z"} 2026-08-14T00:49:55.259417+00:00 https://vulnerability.circl.lu/sighting/37a330a0-ccc5-42ac-80f7-a5ab658a2a8b/export 2026-09-15T18:45:28.621576+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "37a330a0-ccc5-42ac-80f7-a5ab658a2a8b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-73667", "type": "seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3msyu3a5ow32z", "content": "\ud83d\udfe0 CVE-2026-73667 - High (8.8)\n\nOpenChoreo is a complete, open-source developer platform for Kubernetes.
