Overview

flowise is a Flowiseai Server

Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes over the /api/v1/chatflows endpoint. A user can gain unauthorized access to and modify sensitive attributes, such as deployment status, visibility, workspace assignment, and metadata, by including additional fields in the request body, such as:

  • deployed

  • isPublic

  • workspaceId

  • createdDate

  • updatedDate

  • category

  • type

This enables cross-workspace resource reassignment and unauthorized changes to deployment and visibility settings.
