Backstage may expose sensitive information in Scaffolder task failure events
### Impact Under specific template and failure conditions, an authenticated user may be able to retrieve sensitive values from Scaffolder task events. This can expose backend-managed credentials used during task execution. ### Patches Patched in `@backstage/plugin-scaffolder-backend` version `4.1.0` ### Workarounds - Restrict Scaffolder template execution and task-event access to trusted users until the patched version is deployed.
