CVE-2026-90896Network attack vectorHinoki check available

Unauthenticated buyer data disclosure via session lookup

Published Sep 14, 2026 · Updated Sep 14, 2026

Missing authentication in the checkout session endpoint in MarcosCamara01 Ecommerce Template before 91e273c allows remote attackers to read buyer data. The GET handler passes an attacker-supplied session_id to stripe.checkout.sessions.retrieve() and returns the full session without verifying an application session or ownership. Possession of a valid Stripe Checkout Session identifier is required, exposing buyer contact and billing details, payment amount, and the internal user identifier.
