Summary
Flowise prior to version 3.1.2 has a mass assignment vulnerability in the assistant update endpoint. An authenticated user can modify server-controlled properties such as workspaceId, createdDate, and updatedDate. Due to missing server-side validation and authorization checks, an attacker can manipulate the workspaceId field and reassign assistants to arbitrary workspaces.
Risk Assessment
In multi-workspace environments, this breaks tenant isolation, potentially leading to unauthorized access to other users' data.
Recommendation
Update Flowise to version 3.1.2 or later.
Original NVD description (English source)
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 assistant update endpoint of FlowiseAI. The endpoint allows authenticated users to modify server-controlled properties such as workspaceId, createdDate, and updatedDate when updating an assistant resource. Due to missing server-side validation and authorization checks, an attacker can manipulate the workspaceId field and reassign assistants to arbitrary workspaces. This breaks tenant isolation in multi-workspace environments. This issue has been patched in version 3.1.2.
