CVE-2026-46478 [HIGH] CWE-915 FlowiseAI: DatasetRow create+update mass-assignment allows cross-workspace row takeover
FlowiseAI: DatasetRow create+update mass-assignment allows cross-workspace row takeover
## Summary
**Type:** Mass assignment via `Object.assign(entity, body)` -> client-controlled `workspaceId` (and on create, `id`) overwritten on the DatasetRow entity -> cross-workspace data takeover and IDOR.
**File:** `packages/server/src/services/dataset/index.ts`
**Root cause:** The DatasetRow controller/service constructs a `new DatasetRow()` and copies the request body into it via `Object.assign(...)` without an explicit field allowlist. The request body therefore can include `workspaceId`, `id`, `createdDate`, `updatedDate`. The server only rebinds *some* of these after the assign (e.g. on create, it overwrites `workspaceId` but not `id`; on update, it overwrites `id` but not `workspaceId`). The
