QID 980261: Nodejs (npm) Security Update for @backstage/plugin-scaffolder-backend (GHSA-pvv8-8fx9-h673)

Security update has been released for @backstage/plugin-scaffolder-backend to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

A malicious actor could read sensitive files from the environment where Scaffolder tasks are run. The attack is executed by crafting a custom Scaffolder template with a `publish:github:pull-request` action using a particular source path. When the template is executed the sensitive files would be included in the published pull request.

This vulnerability is mitigated by the fact that an attacker would need access to create and register templates in the Backstage catalog, and that the attack is very visible given that the exfiltration happens via a pull request.

  • CVSS V3 rated as Medium - 4.9 severity.
  • CVSS V2 rated as Medium - 4 severity.
    • Solution
    The vulnerability is patched in the `0.15.9` release of `@backstage/plugin-scaffolder-backend`.
