A logging flaw in Backstage Scaffolder’s `fetch:template` action up to `@backstage/plugin-scaffolder-backend` **2.1.0** may write template secrets to logs. The action emitted a duplicate, pre-redaction copy of input parameters, so values provided via the `{{ secrets }}` bag could appear in local/server logs when the action ran. Exploitation requires use of the `secrets` argument and access to Scaffolder/build logs; integrity and availability are unaffected.

* **Fix:** upgrade to `2.1.1`, which removes the duplicate log path and ensures secrets are redacted. * **Mitigation:** avoid passing `{{ secrets }}` to `fetch:template` if upgrade is not possible.
