Summary
Backstage Scaffolder plugin vulnerable to Server-Side Request Forgery
Details

Impact

A vulnerability is identified in Backstage Scaffolder template functionality where Server-Side Template Injection (SSTI) can be exploited to perform Git config injection. The vulnerability allows an attacker to capture privileged git tokens used by the Backstage Scaffolder plugin. With these tokens, unauthorized access to sensitive resources in git can be achieved. The impact is considered medium severity as the Backstage Threat Model recommends restricting access to adding and editing templates in the Backstage Catalog plugin.

Patches

The issue has been resolved in versions v0.4.12, v0.5.1 and v0.6.1 of the @backstage/plugin-scaffolder-node package. Users are encouraged to upgrade to this version to mitigate the vulnerability.

Workarounds

Users can ensure that templates do not change git config.
