CVE-2026-90650

Estado: AplazadaAlta (7.2)—

The MotoPress Hotel Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Stripe Webhook event object 'id' in all versions up to, and including, 6.2.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Leer descripción completaMostrar menos

The premium Stripe webhook listener only verifies the webhook signature when an optional Stripe signing secret has been configured; because that secret is empty by default, a forged webhook is accepted without cryptographic verification, and the attacker-controlled event object 'id' (e.g. a forged 'refund.created' refund id) is written unescaped into the payment log and later echoed unsanitized when an administrator views the payment. An attacker must know a valid Stripe PaymentIntent ID for an existing payment to route the forged webhook to a payment record. Note: The vulnerable webhook handler (webhook-listener.php) is part of the premium Stripe gateway integration and is not present in the lite plugin directory.
