Flowise - PII Disclosure on Unauthenticated Forgot Password Endpoint

Medium

Synopsis

The /api/v1/account/forgot-password endpoint returns the full user object including PII (id, name, email, status, timestamps) in the response body instead of a generic success message. This exposes sensitive user information to unauthenticated attackers who only need to know a valid email address.

Solution

Upgrade to Flowise version 3.0.13 or later
