Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key through the createDocumentStore, updateDocumentStore, and upsertDocStore paths in documentstore/index.ts and documentstore/index.ts.

This lets an authenticated user hijack document-store ownership and alter or replace another workspace’s stored documents and configuration.
