@backstage/plugin-scaffolder-backend: Possible exposure of defaultEnvironment secrets using dry-run endpoint
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @backstage/plugin-scaffolder-backend | >= 3.1.0, < 3.1.5 | 3.1.5 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Authenticated users with permission to execute scaffolder dry-runs can gain access to server-configured environment secrets through the dry-run API response. Secrets are properly
redacted in log output but not in all parts of the response payload.
Deployments that have configured `scaffolder.defaultEnvironment.secrets` are affected.
### Patches
This is patched in `@backstage/plugin-scaffolder-backend` version 3.1.5
### Workarounds
Remove or empty the `scaffolder.defaultEnvironment.secrets` configuration from `app-config.yaml`. Alternatively, restrict access to the scaffolder dry-run functionality via the
permissions framework.
