Published### Impact An authenticated Backstage user who can read another user's Scaffolder task may receive internal execution data. In deployments where that data contains credentials for an external service, this may permit disclosure and unauthorized changes in that external service. ### Patches Patched in `@backstage/plugin-scaffolder-backend` version `4.1.0` ### Workarounds - Configure `scaffolder.task.read` with the `isTaskOwner` condition so users can only read tasks they created. - Restrict affected integrations and workflows to trusted operators until an upgrade is available.
