Summary
BoxyHQ Enterprise SaaS Starter Kit through 1.6.0 contains a missing authorization flaw (CWE-862) because its payment routes skip the team_payments permission check. Authenticated MEMBER or ADMIN users can call create-portal-link, create-checkout-session, and products to open Stripe billing portals, view invoices, change payment methods, or alter subscriptions. Non-owner team members can therefore manage billing.
