Backstage: Incorrect authorization in scaffolder task listing

Impact

An authenticated internal user may be able to view metadata for scaffolder tasks outside the visibility intended by a deployment's permission policy. Stored task secrets are not included in the affected response, and no integrity or availability impact was identified.

Patches

Patched in @backstage/plugin-scaffolder-backend version 4.1.0

Workarounds

• Restrict the scaffolder task-list endpoint at the ingress or authenticating proxy to users who are permitted to view all tasks.
• Avoid placing sensitive values in template input parameters until the patched package is deployed.
