Summary
Template Secret leakage in logs in Scaffolder when using `fetch:template`
Details

Impact

Duplicate logging of the input values in the fetch:template action in the Scaffolder meant that some of the secrets were not properly redacted. If you're not passing through ${{ secrets.x }} to fetch:template there is no impact.

Patches

This issue has been resolved in 2.1.1 of the scaffolder-backend plugin.

Workarounds

Template Authors can remove the use of ${{ secrets }} being used as an argument to fetch:template.
