GHSA-2g8g-63j4-9w3r
RCE vulnerability affecting v1beta3 templates in @backstage/plugin-scaffolder-backend
Quick fix
GHSA-2g8g-63j4-9w3r — @backstage/plugin-scaffolder-backend: upgrade to the fixed version with the command below.
npm install @backstage/plugin-scaffolder-backend@0.15.14Details
The templating library used by the scaffolder backend assumes that templates are trusted which is an undesired property of the scaffolder-backend. This has now been mitigated by sandboxing the template code execution.
### Impact A malicious actor with write access to a registered scaffolder template could manipulate the template in a way that allows for remote code execution on the scaffolder-backend instance. This was only exploitable in the template yaml definition itself and not by user input data.
### Patches This is vulnerability is patched in version `0.15.14` of `@backstage/plugin-scaffolder-backend`.
