Alert meAnalysisAIv1 – Sep 15, 2026
Unauthenticated retrieval of Stripe Checkout Session objects in the MarcosCamara01 Ecommerce Template (before commit 91e273c) exposes buyer personally identifiable information to anyone holding a session id. The GET handler at /api/stripe/checkout_sessions calls stripe.checkout.sessions.retrieve() and returns the full object — buyer name, email, phone, billing address, amount paid and internal userId — without ever calling auth.api.getSession() or verifying that the session belongs to the caller, even though sibling endpoints such as POST /api/stripe/payment already enforced authentication. Exploitation is not confirmed in the wild and no public exploit code was identified, but the session_id is written into the buyer's own success_url (/result?session_id={CHECKOUT_SESSION_ID}), so it leaks through Referer headers, analytics, access logs and shared-machine browser history, making the flaw practically reachable rather than purely theoretical.

Lifecycle Timeline
2DescriptionCVE.org
Missing Authentication for Critical Function (CWE-306) in the checkout session lookup handler (src/app/api/stripe/checkout_sessions/route.ts), exposed at GET /api/stripe/checkout_sessions, in MarcosCamara01 Ecommerce Template before commit 91e273c allows a remote, unauthenticated attacker holding a valid Stripe Checkout Session id (cs_...) to retrieve the full session object, including the buyer's name, email, phone, billing address, amount paid and internal userId, because the GET handler calls stripe.checkout.sessions.retrieve() and returns the result without checking for an authenticated session or session ownership. Sibling endpoints such as POST /api/stripe/payment already enforced authentication via auth.api.getSession(); this endpoint had no access control whatsoever. The session_id is exposed in the buyer's own browser URL after payment (success_url = /result?session_id={CHECKOUT_SESSION_ID}), so it leaks through Referer headers, analytics tools, server access logs and shared-machine browser history, resulting in disclosure of the buyer's personal data to an unauthenticated actor.
