| Package | Affected versions | Patched versions |
|---|---|---|
| backstage/plugin-scaffolder-backend | ≥ 3.1.0, < 3.1.5 | 3.1.5 |

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.
This is patched in @backstage/plugin-scaffolder-backend version 3.1.5
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.
