WP Travel Engine Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the WP Travel Engine WordPress plugin, affecting versions prior to 5.3.1. The issue arises because the plugin does not properly escape the Description field in Trip Destination, Activities, Trip Type, and Pricing Category pages. This flaw allows users with editor roles to inject malicious scripts, even when the unfiltered_html capability is restricted.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the affected page.

Reproduction

To reproduce this vulnerability, an editor or admin can add or edit a Trip Destination, Activity, Type, or Pricing Category. While in the Description field, insert a payload such as an image tag with an 'onerror' attribute. The injected script will be executed when the category or trip is viewed.

Remediation

Users are advised to update the WP Travel Engine plugin to version 5.3.1 or later.
