Backstage is an open framework for building developer portals. From 0.3.0 until 0.3.8, the @backstage/plugin-scaffolder-backend-module-sentry package is affected by improper input validation in sentry scaffolder actions. An authenticated internal user who can execute the affected actions may cause the backend to contact unintended destinations and disclose Sentry integration credentials. Subsequent impact depends on network reachability and the privileges granted to the configured token. This issue is fixed in version 0.3.8.

 https://vulnerability.circl.lu/vuln/ghsa-g734-fhp4-7mfp GHSA-g734-fhp4-7mfp — Backstage: Improper input validation in Sentry scaffolder actions 2026-10-07T23:05:47.522910+00:00

Affected: npm: @backstage/plugin-scaffolder-backend-module-sentry

### Impact

An authenticated internal user who can execute the affected actions may cause the backend to contact unintended destinations and disclose Sentry integration credentials. Subsequent impact depends on network reachability and the privileges granted to the configured token.

### Patches

Upgrade `@backstage/plugin-scaffolder-backend-module-sentry` to version `0.3.8` or later. The fixed package is available in [Backstage v1.54.8](https://github.com/backstage/backstage/releases/tag/v1.54.8) and [Backstage v1.55.0](https://github.com/backstage/backstage/releases/tag/v1.55.0).

The update removes custom action-level `apiBaseUrl` values. Move any such value to `scaffolder.sentry.apiBaseUrl` before upgrading.

### Workarounds

- Disable the affected actions until the patched package is deployed. - Restrict `scaffolder.action.execute` permission for the affected Sentry actions to trusted users and templates.
