CVE-2026-103423 Details
Description
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.
A vulnerability exists in the Booking Package plugin for WordPress, in all versions through 1.7.29, allowing authorization bypass. The plugin fails to properly verify user authorization for certain actions, enabling unauthenticated attackers to access personally identifiable information of customers from the booking_package_booked_customers table. This information includes names, email addresses, phone numbers, physical addresses, and cancellation tokens. The vulnerability arises because the nonce intended to protect the endpoint is a public CSRF token available in the localized booking_package JavaScript object on pages with the [booking_package] shortcode or widget. This token can be easily collected by unauthenticated users, creating an ineffective authentication barrier.
Users are advised to update the Booking Package plugin to version 1.7.30 or a newer patched version.
