CVE-2018-19249: Stripe API

High severity, CVSS 7.5. EPSS: 1.4% chance of exploitation in the next 30 days.

The Stripe API v1 allows remote attackers to bypass intended access restrictions by replaying api.stripe.com /v1/tokens XMLHttpRequest data, parsing the response under the object card{}, and reading the cvc_check information if the creation is successful without charging the actual card used in the transaction.
