Upgrade flowise to version 3.1.2 or higher.
Overview
flowise is a Flowiseai Server
Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes in the Object.assign process. An attacker can gain unauthorized access to and control over data across different workspaces by supplying JSON bodies that overwrite ownership fields such as workspaceId or id during create or update operations. This allows the attacker to move dataset rows between workspaces they do not belong to, exposing sensitive data to unintended parties and breaking workspace isolation. This is only exploitable if the attacker is an authenticated user with edit permissions for the target dataset row and can enumerate or guess valid workspace UUIDs.
