Executive Summary

The VikBooking Hotel Booking Engine & PMS plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'email' parameter in all versions up to and including 1.8.8.

This vulnerability exists because the plugin does not properly sanitize input or escape output, allowing attackers to inject malicious web scripts.

These injected scripts are stored and executed whenever a user accesses the affected page, potentially compromising user security.

Impact Analysis

This vulnerability allows unauthenticated attackers to inject and execute arbitrary scripts on pages viewed by users.

Such script execution can lead to theft of user credentials, session hijacking, or other malicious actions performed in the context of the affected website.

Because the vulnerability has a CVSS v3.1 base score of 7.2 with network attack vector and no privileges required, it is relatively easy for attackers to exploit remotely.
