- CustomTemplate create+update mass-assignment

- Assistant create+update mass-assignment allows cross-workspace assistant takeover

- DatasetRow create+update mass-assignment

- Dataset create+update mass-assignment

- Evaluation create+update mass-assignment

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version
    3.1.2, a mass assignment vulnerability exists in the variable update endpoint of FlowiseAI. The endpoint
    allows authenticated users to modify server-controlled properties such as workspaceId, createdDate, and
    updatedDate when updating a variable resource. Due to missing server-side validation and authorization
    checks, an attacker can manipulate the workspaceId field and reassign variables to arbitrary workspaces.
    This behavior may break tenant isolation in multi-workspace environments. This issue has been patched in
    version 3.1.2. (CVE-2026-42861)
