Summary

@backstage/plugin-scaffolder-backend: Possible exposure of defaultEnvironment secrets using dry-run endpoint

Details

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.
