Overview
flowise is a Flowiseai Server
Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the Object.assign function. An attacker can manipulate internal entity fields such as id, createdDate, and chatId by including them in the request body to the /api/v1/leads endpoint, thereby bypassing server-side auto-generation and validation. This allows unauthorized users to control sensitive attributes, potentially leading to data integrity violations, audit trail manipulation, and business logic bypasses by sending crafted requests to the public API endpoint.
