Next Saas Stripe Starter CVE-2026-4548

Immediately upgrade next-saas-stripe-starter to a patched version if the maintainer has released one, or apply a manual security patch to actions/update-user-role.ts that enforces proper authorization checks before role modifications (verify the authenticated user is an administrator and has explicit permission to modify the target user's role). As a compensating control pending patch availability, implement server-side middleware that restricts the updateUserRole action to users with administrative roles via middleware enforcement in your Next.js configuration, and audit all recent role modification logs for unauthorized changes. Review and restrict API endpoint access to the role update function through network controls and request signing mechanisms if operating in a critical environment. Monitor the official next-saas-stripe-starter GitHub repository (https://github.com/mickasmt/next-saas-stripe-starter/releases) for security updates and consider contributing a fix upstream if you identify the precise authorization logic flaw.
