CVE-2026-70476 Details
Description
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, several organization billing 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 that the identifier belongs to the authenticated user's organization. An authenticated attacker can perform unauthorized Stripe subscription operations on other tenants, including changing subscription plans or modifying seat quantities, resulting in financial impact and service disruption. This issue is fixed in 3.1.3.
A broken access control vulnerability has been identified in Flowise, specifically in the organization billing endpoints of the server's enterprise package, prior to version 3.1.3. These endpoints accept Stripe subscription IDs provided by users without verifying if they belong to the authenticated user's organization. This flaw enables an authenticated attacker to perform unauthorized operations on the Stripe subscriptions of other organizations, such as changing subscription plans or modifying the number of seats, which could lead to financial repercussions and service disruptions.
Users can update to Flowise version 3.1.3 or later, where this vulnerability has been patched.
