Technical details
Flowise suffers from an Insecure Direct Object Reference (IDOR) / Broken Access Control vulnerability in the `update-additional-seats` and `update-subscription-plan` routes within `organization.route.ts`. The server accepts a `subscriptionId` directly from the request body and processes billing changes via the Stripe integration without verifying if the subscription belongs to the authenticated user's organization. An attacker can obtain a victim's `subscriptionId` through other API endpoints and then issue POST requests to modify seat quantities or change subscription plans. This issue is fixed in version 3.1.3.
