CVE-2026-70476 is an improper authorization vulnerability in Flowise versions before 3.1.3. Organization billing operations accept a client-supplied Stripe subscription identifier without validating that the subscription is owned by the authenticated user’s active organization. This permits a tenant to target another organization’s subscription and perform cross-tenant billing changes.
