- CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Description
### Impact An authenticated user who can create and read scaffolder tasks may be able to observe sensitive values in task logs in deployments with restrictive action permissions and affected templates. Exploitation requires a denied action whose input contains such a value. ### Patches Patched in `@backstage/plugin-scaffolder-backend` version `4.1.0` ### Workarounds - Restrict scaffolder task creation and task-log reading to trusted users. - Avoid placing centrally managed sensitive values in inputs to actions that may be denied until upgrading. ### References - [Backstage threat model](https://backstage.io/docs/overview/threat-model/) - [Backstage permissions overview](https://backstage.io/docs/permissions/overview/)
