First published: Thu Oct 03 2024(Updated: )

### 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](https://backstage.io/docs/conf/writing#environment-variable-substitution) available for Backstage configuration. ### References If you have any questions or comments about this advisory: Open an issue in the [Backstage repository](https://github.com/backstage/backstage) Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)
