CVE-2026-100686

Budibase versions before 3.45.0 fail to validate per-app authorization in the POST /api/global/groups/:groupId/apps endpoint, allowing builders to assign application roles across workspace boundaries. A builder of a single workspace can exploit missing per-app authorization checks to grant themselves admin roles in other workspaces by modifying user group role mappings.
