            "summary": "Improper Control of Generation of Code ('Code Injection')\nBackstage is an open platform for building developer portals. The Backstage scaffolder-backend plugin uses a templating library that requires sandbox, as it by design allows for code injection. The library used for this sandbox so far has been `vm2`, but in light of several past vulnerabilities and existing vulnerabilities that may not have a fix, the plugin has switched to using a different sandbox library. 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. This is vulnerability is fixed in version 1.15.0 of `@backstage/plugin-scaffolder-backend`.",

            "summary": "Template Secret leakage in logs in Scaffolder when using `fetch:template`\nA logging flaw in Backstage Scaffolder’s `fetch:template` action up to `@backstage/plugin-scaffolder-backend` **2.1.0** may write template secrets to logs. The action emitted a duplicate, pre-redaction copy of input parameters, so values provided via the `{{ secrets }}` bag could appear in local/server logs when the action ran. Exploitation requires use of the `secrets` argument and access to Scaffolder/build logs; integrity and availability are unaffected.\n\n*   **Fix:** upgrade to `2.1.1`, which removes the duplicate log path and ensures secrets are redacted.\n*   **Mitigation:** avoid passing `{{ secrets }}` to `fetch:template` if upgrade is not possible.\n\n> Open an issue in the [Backstage repository](https://github.com/backstage/backstage)\n>\n> Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)",
