Technical details

The vulnerability is a Stored XSS flaw in the premium Stripe webhook handler (webhook-listener.php) caused by insufficient input sanitization and output escaping of the Stripe webhook event object 'id' field. The webhook endpoint only verifies the webhook signature when a Stripe signing secret is configured; since this secret is empty by default, attackers can send forged webhooks without cryptographic verification. The attacker-controlled 'id' field is written unescaped into the payment log and later echoed unsanitized when an administrator views the payment record in the WordPress admin panel. Successful exploitation requires knowledge of a valid Stripe PaymentIntent ID for an existing payment to route the forged webhook to the correct payment record. The vulnerability affects all versions up to and including 6.2.4.
