CVE-2026-44678Public exploitNetwork attack vector

Cross-tenant preview deletion via unscoped UUID lookup

Published May 14, 2026 · Updated May 14, 2026

Authorization bypass in Tuist Server 1.180.8 and earlier allows remote authenticated users to delete cross-tenant previews by UUID. The delete action resolves preview_id with an unscoped Repo.get_by lookup and never binds the result to the URL-selected project. Any account with at least one project can delete a victim preview and associated build records when its UUID is known; recovery requires database backups.
