CVE-2026-73667Network attack vector

Authenticated command execution via interpolated workflow parameters

Published Aug 13, 2026 · Updated Aug 13, 2026

OS command injection in OpenChoreo before 1.0.4, 1.1.0 through 1.1.3, and 1.2.0-rc.1 allows remote authenticated users to execute commands. Workflow Plane templates substitute developer-controlled Argo parameters directly into sh -c script text, so shell metacharacters change the executed program. Access to configure and trigger an affected workflow is required; commands run inside its pod, and privileged Podman templates without user-namespace isolation can expose host resources.
