The potential impact includes exposure of sensitive task information if certain criteria are met, including knowledge of task secrets and structure. Organizations using Backstage should prioritize upgrading to version 4.1.0 to mitigate this risk.

Original NVD Description

Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.
