Backstage may expose sensitive information in Scaffolder task failure events
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @backstage/plugin-scaffolder-backend | < 4.1.0 | 4.1.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
