The Booking Package plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.29 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve personally identifiable information for every booked customer stored in the booking_package_booked_customers table, including names, email addresses, phone numbers, physical addresses, and cancellation tokens. The nonce nominally protecting the endpoint is a public CSRF token emitted in the localized booking_package JavaScript object on any page rendering the [booking_package] shortcode or widget, making it trivially harvestable by unauthenticated visitors and providing no effective authentication barrier.
