Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, evaluation create and update mass-assignment allows cross-workspace evaluation takeover. This issue has been patched in version 3.1.2.

GHSA-mq53-pc65-wjc4 — FlowiseAI: Evaluation create+update mass-assignment allows cross-workspace evaluation takeover

Affected: npm: flowise

## Summary

**Type:** Mass assignment via `Object.assign(entity, body)` -> client-controlled `workspaceId` (and on create, `id`) overwritten on the Evaluation entity -> cross-workspace data takeover and IDOR. **File:** `packages/server/src/services/evaluations/index.ts` **Root cause:** The Evaluation controller/service constructs a `new Evaluation()` 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 remaining client-controlled values land directly on the persisted row, breaking workspace isolation. Same root pattern as the evaluation entity's sibling controllers and as `DocumentStore` before it was patched in commit 840d2ae.

## Affected Code

**File:** `packages/server/src/services/evaluations/index.ts`

```ts // at line 69 Object.assign(newEvaluation, body) // <-- BUG: body.id, body.workspaceId, body.createdDate, body.updatedDate accepted ```

**Why it's wrong:** `Object.assign(target, source)` copies every own enumerable property of `source` onto `target`. The TypeORM/SQL persistence layer below it does not strip ownership-bearing columns, so `workspaceId` set in the request body lands as the new `workspaceId` of the persisted row. The DocumentStore patch (comm…
