This is due to a flawed permission check in the `paidy_webhook_permission_check` function that unconditionally returns `true` when the webhook signature header is omitted. This makes it possible for unauthenticated attackers to bypass payment verification and fraudulently mark orders as \"Processing\" or \"Completed\" without actual payment via a crafted POST request to the Paidy webhook endpoint."
