Summary

Unexpected visibility of environment variable configurations in @backstage/plugin-app-backend

Details

Impact

Configuration supplied through APP_CONFIG_* environment variables, for example APP_CONFIG_backend_listen_port=7007, where unexpectedly ignoring the visibility defined in configuration schema. This occurred even if the configuration schema specified that they should have backend or secret visibility. This was an intended feature of the APP_CONFIG_* way of supplying configuration, but now clearly goes against the expected behavior of the configuration system. This behavior leads to a risk of potentially exposing sensitive configuration details intended to remain private or restricted to backend processes.

Patches

The issue has been resolved in version 0.3.75 of the @backstage/plugin-app-backend package. Users are encouraged to upgrade to this version to mitigate the vulnerability.

Workarounds

As a temporary measure, avoid supplying secrets using the APP_CONFIG_ configuration pattern. Consider alternative methods for setting secrets, such as the environment substitution available for Backstage configuration.
