Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Backstage is an open framework for building developer portals. Prior to 1.54.6, scaffolder source-control
 actions may not consistently enforce intended credential boundaries. An authenticated user could cause an
 affected action to fall back to broader integration credentials and perform operations with more access
 than intended. This issue is fixed in 1.54.6 when operators also enable
 scaffolder.requireScmUserCredentials after upgrading. (CVE-2026-106462)

Solution

Update the @backstage/plugin-scaffolder-backend-module-gitlab library and its related packages to version 0.11.10 or later.
