Résumé
Backstage has improper authorization in GitLab organizational user ingestion
Détails de l’avis
Impact
Deployments that enable GitLab organization event ingestion and rely on scoped catalog users as an access boundary may admit an unintended catalog identity. Depending on sign-in and permission configuration, this may allow unauthorized access with the permissions of a standard authenticated user.
Patches
- Upgrade
@backstage/plugin-catalog-backend-module-gitlabto version0.8.7.
Workarounds
- Disable event-driven GitLab organization ingestion and rely on scheduled discovery until upgrading.
- Enforce organization membership independently at the authenticating proxy or sign-in resolver.
