AI Analysis
Technical Summary
FlowiseAI Flowise, a drag-and-drop interface for building customized large language model flows, contains an access control flaw in organization billing endpoints prior to version 3.1.3. Specifically, endpoints in packages/server/src/enterprise/routes/organization.route.ts and packages/server/src/enterprise/controllers/organization.controller.ts accept attacker-controlled Stripe subscriptionId values without verifying ownership by the authenticated user's organization. This allows an authenticated attacker to perform unauthorized Stripe subscription operations on other tenants, including modifying subscription plans and seat quantities. The vulnerability is tracked as CVE-2026-70476 and is fixed in version 3.1.3.
Potential Impact
An authenticated attacker can perform unauthorized operations on Stripe subscriptions belonging to other tenants, potentially altering subscription plans or seat quantities. This can result in financial loss and disruption of service for affected organizations.
Mitigation Recommendations
Upgrade Flowise to version 3.1.3 or later, where this access control vulnerability has been fixed. No other mitigation steps are indicated by the vendor advisory.
