@backstage/plugin-scaffolder-backend: Possible exposure of defaultEnvironment secrets using dry-run endpoint
3.1.0 - 3.1.4
3.1.0 - 3.1.4

Summary

@backstage/plugin-scaffolder-backend: Possible exposure of defaultEnvironment secrets using dry-run endpoint

Details

Impact

Authenticated users with permission to execute scaffolder dry-runs can gain access to server-configured environment secrets through the dry-run API response. Secrets are properly redacted in log output but not in all parts of the response payload.

Deployments that have configured scaffolder.defaultEnvironment.secrets are affected.

Patches

This is patched in @backstage/plugin-scaffolder-backend version 3.1.5

Workarounds

Remove or empty the scaffolder.defaultEnvironment.secrets configuration from app-config.yaml. Alternatively, restrict access to the scaffolder dry-run functionality via the permissions framework.
