What the vulnerability does

01Description

The WP Travel Engine – Tour Booking Plugin – Tour Operator Software plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.8.4. 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 view private booking billing details — including the victim customer's first name, last name, email address, street address, city, and phone number — rendered as default values in checkout form fields by binding an arbitrary booking ID to the attacker's session. The only access control on the endpoint is a frontend nonce that is publicly emitted to all visitors via the wteL10n global on trip pages, meaning it provides CSRF protection only and does not restrict unauthenticated access.

Explanation of Vulnerability in Simple Terms

02Summary

WP Travel Engine versions 6.8.4 and earlier lack proper authorization checks, allowing unauthenticated attackers to read sensitive data. An attacker can access information without logging in or requiring any special privileges. Site administrators should update immediately to a version newer than 6.8.4 to prevent unauthorized data exposure.
