+  "details": "### Impact\n\nThe `stripe/charge` payment method did not check Stripe's `Idempotent-Replayed` response header when creating PaymentIntents. An attacker could replay a valid credential containing the same `spt` token against a new challenge, and the server would accept the replayed Stripe PaymentIntent as a new successful payment without actually charging the customer again. This allowed an attacker to pay once and consume unlimited resources by replaying the credential.\n\n### Patches\n\nFixed in 0.4.11. The server now checks the `Idempotent-Replayed` header and rejects replayed PaymentIntents.\n\n### Workarounds\n\nThere are no workarounds available for this vulnerability.",
