OpenChoreo is a developer platform for Kubernetes. Prior to 1.0.4, 1.1.4, and 1.2.1, the OpenChoreo Backstage backend hardcoded backend.auth.dangerouslyDisableDefaultAuthPolicy and auth.providers.guest.dangerouslyAllowOutsideDevelopment to true, exposing /api/* without authentication and allowing unauthenticated catalog reads, scaffolder log reads, and catalog location creation or deletion. This issue is fixed in versions 1.0.4, 1.1.4, and 1.2.1.
