What the vulnerability does
01Description
The WP Hotel Booking plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.2.7. This is due to the plugin exposing the 'hotel_booking_fetch_customer_info' AJAX action to unauthenticated users without proper capability checks, relying only on a nonce for protection. This makes it possible for unauthenticated attackers to retrieve sensitive customer information including full names, addresses, phone numbers, and email addresses by providing a valid email address and a publicly accessible nonce.
Explanation of Vulnerability in Simple Terms
02Summary
WP Hotel Booking versions 2.2.7 and earlier expose sensitive information that can be accessed over the network without authentication. An attacker can retrieve partial data from the plugin without needing to log in or interact with a user. Site administrators should update to a version newer than 2.2.7 to prevent unauthorized information disclosure.
