CVE-2026-17087: Missing authorization vulnerability
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.
