Overview
@backstage/plugin-scaffolder-backend-module-github is a The github module for @backstage/plugin-scaffolder-backend
Affected versions of this package are vulnerable to Incorrect Authorization via SCM scaffolder actions in bitbucketServer.ts and related action files, where the actions fall back to server-side integration credentials when no user-supplied token is provided. An authenticated attacker can trigger SCM operations (repository creation, pull request creation, and similar actions) that execute under the server's privileged integration credentials rather than the user's own credentials, allowing privilege escalation across SCM resources. This affects all SCM provider modules in the scaffolder backend, including Bitbucket Server, Bitbucket Cloud, Azure DevOps, and GitHub.
