GHSA-mq4r-h2gh-qv7x: Flowise Allows Mass Assignment in `/api/v1/leads` Endpoint

A mass assignment vulnerability (a type of attack where an attacker controls internal fields by sending them in a request) exists in Flowise's `/api/v1/leads` endpoint, allowing unauthenticated users to override auto-generated fields like `id`, `createdDate`, and `chatId` by including them in the request body. The vulnerability occurs because the code uses `Object.assign()` to copy all properties from user input directly into the database entity without filtering, bypassing the intended auto-generation of these fields.
