Details

Template Secret leakage in logs in Scaffolder when using `fetch:template` ### 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`. ### References If you have any questions or comments about this advisory: Open an issue in the [Backstage repository](https://github.com/backstage/backstage) Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)
