Overview

CVE-2026-17087 is a high-severity vulnerability. It was published on August 16, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
