Vulnerability Overview

The WP Travel – Ultimate Travel Booking System, Tour Management Engine plugin for WordPress is vulnerable to Payment Bypass in all versions up to 11.8.1 (exclusive). This makes it possible for unauthenticated attackers to bypass payments by manipulating order statuses.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in WP Travel < 11.8.1 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For WP Travel the fix is 11.8.1: builds < 11.8.1 are affected, anything from 11.8.1 onward is not.

Remediation

Update to version 11.8.1, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: WP Travel 11.8.1 closes this, and updating the plugin is the step that ends it.
