Authorization Bypass in WP Travel Engine Plugin

Publication date: 2026-08-16

Last updated on: 2026-08-16

Assigner: Wordfence

Description
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.

Executive Summary

This vulnerability is an authorization bypass in the WP Travel Engine plugin for WordPress. It allows unauthenticated attackers to view private booking billing details by exploiting improper user verification. Attackers can bind an arbitrary booking ID to their session and access sensitive customer data like names, email, address, and phone number through checkout form fields.

Detection Guidance

This vulnerability allows unauthenticated attackers to access private booking billing details via authorization bypass. To detect it, inspect WordPress sites running the WP Travel Engine plugin versions up to 6.8.4 for unauthorized access to checkout endpoints or exposed customer data. Check server logs for unusual requests to /wp-json/wte/v1/bookings or similar endpoints.

Impact Analysis

If you use the WP Travel Engine plugin, attackers could steal your customers' personal and billing information. This could lead to identity theft, fraud, or reputational damage for your business. The vulnerability requires no authentication, making it easier for attackers to exploit.

Compliance Impact

This vulnerability likely violates GDPR due to unauthorized access to personal data and potential failure to implement proper data protection measures. It may also conflict with HIPAA if billing details include protected health information. Organizations could face fines or legal consequences for non-compliance.

Mitigation Strategies

Update the WP Travel Engine plugin to the latest version beyond 6.8.4 immediately to patch the authorization bypass vulnerability.
