CVE-2026-112293

Description

BoxyHQ Enterprise SaaS Starter Kit through 1.6.0 contains a missing authorization vulnerability that allows non-owner team members to manage billing because 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.
